0252 D5 Injectors, Starting Problem What volvo contribution?

[sail&fish]

Only 5 months a Volvo owner (02/52 V70 D5 82,000 miles) and I have started having winter starting problems. Reading this forum I guessed it may be injectors but took it to a local specialist just in case. He put it on the diagnostic (no fault found) and cleaned the injectors. The problem is still there and it requires a lot of cranking to start- this morning 7 degrees centigrade.

I have contacted the local Volvo dealer and booked it in for next week. He said they have had some problems with 2002 cars and that if it was injectors he would contact Volco UK for a contribution. He also pointed out that the car has not been volvo serviced for the last 2 years; it has been serviced in a volvo specialist.

So my question is what sort of contributuon should I be looking for from Volvo and what sort of noises should I make to them?

thanks in advance

Hello and welcome to the forums.

This might be of interest.

At that age and mileage I doubt there will be any contribution at all, but its worth pressing the point you never know.

Thanks for help.

Well today the dealer diagnosed the need for 5 injectors. He had spoken to Volvo UK who said they could not assist as the car had not been fully main dealer serviced, though injectors are not a service item.

I then spoke to Volvo Customer Relations (08457 564636). They could not express an opinion:


about the length of time injectors should last.
whether it was primarily a 2002 model problem.
whether dealer servicing would have extended the life of the injectors.
if 2 pence a mile as the running costs for injectors seemed a lot.


They did say that the last 3 independent volvo specialist services did not constitute a volvo service history and therefore they could not show goodwill in this case.

So £1500 it is and I'll never recommend a D5 to anybody if they are worried about running costs.

[John_C]

That's a pity, if not unexpected :(

You might want to investigate other sources for the injectors, when all's said and done they are just another part (made by Bosch I believe or some other large automotive component company if not) and I suspect you will pay a LOT of money for the "Volvo" stamp on the side of the box.

A good diesel specialist should be able to help you if someone can recommend one in your area?

Cheers,

Hi,

Given that the volvo independent is an ex volvo mechanic and the garage used volvo recommended service components (filters oil etc) then that service is as good as a volvo dealers service - especially for warranty claims - the tie between volvo dealer servicing and car warranties has been broken by trading standards/competition/whatever..

For Volvo to say that it is not good enough would be say that any independent serving is no good - including for warranty claims.

You would be best off advising VCUK of this fact and tell them to look forward o their day in court..
Given that a number of people have had issues with D5 injectors, you are not the only one..

Get your papers from your local county court and see your local CAB and speak to your trading standards people..

Des. . .;)

Well its now fixed; £219.50 for each injector and £178 for diagnosis and fitting. All up a shade under £1500 with the VAT including door to door service. Though unpalatable, I think the garage did right by me. My local independent said he could do it cheaper but that there can be problems getting them out and if that was the case his price would rise; he advised the main dealer route with the fixed price.

I had a look at the OFT ruling on dealer servicing. This only covers manufacturers warranty; it appears that after market warranty are allowed to specify servicing. I did challenge Volvo again that my car had an independent volvo service in line with the OFT ruling and asked they reconsider. There response was:
"Regards to your query concerning a goodwill gesture towards the replacement of injectors in your vehicle. Volvo Customer Relations are unable to assist in terms of offering a goodwill gesture due to the poor servicing history on your vehicle. Volvo Car UK Ltd cannot guarantee the life expectancy of any component. This is why we provide warranties for our vehicles new and used, to assist our customers in the unlikely event that a part for a newly built vehicle should fail or malfunction. After this point, Volvo may consider a goodwill gesture towards the cost of a repair, depending on such factors as age, mileage, service history and customer loyalty"
So for those considering buying a used car, or opting out of main dealer servicing it may be worth considering what the main dealer thinks of independent specialist servicing.

I tried to google a cheaper place to buy injectors but any search with injectors, D5 and volvo in just brings up complaints about early failure - nuff said.

Its extremely unlikely that you needed 5 injectors ... When the problem first arose volvo changed all 5 BUT they later brought out single kits to change just the faulty ones .
It is very quick and easy to determine which injector is faulty it has been described by me and others elsewhere here .

I have never seen more than two faulty injectors on one car ...

At least you will be ok for many years to come now .. and this doesnt happen to ALL 2002 D5's by any means just the odd one here and there out of the 100's of 1000's sold ..

[v8disco]

So hows the starting now. Mine has the same problem but fired this morning at an indicated -7 degrees after no more cranking than usual

I think that's a pretty poor response considering how criminally poor Volvo's main dealer's own standard of servicing has been as far as I'm concerned, While the independants I've used have all been superb.

Yep ! Injector problem diagnose on my XC90 D5 (53 reg) too and 1 faulty injector only changed today at a cost of £335. Fortunately the car was purchase less than a year ago from a volvo dealer so it was cover by the volvo care plan warranty !

I too have a 2002 V70 D5 with 77,000 miles on the clock which has just required all the fuel injectors to be replaced. Would not start intermittently, and after 3 AA men misdiagnosing it as a)camshaft sensor b) fuel rail, and c) new fuel pump (back one by fuel tank) in 2 rotten weeks, we finally ascertained the real problem, and all in the lead up to Christmas. Nice Christmas present of a bill for £1350.

This is obviously a design fault judging by the number of posts on the matter, and the reports of various vehicles (yes even diesels) catching on fire abroad. Yet Volvo UK are refusing me any compensation at the moment. They recalled all D5 S60s for problems with fuel leaks (SAME ENGINE) yet didn't bother with the V70 D5s. When I asked them why they skirted around the issue by saying that they responded to the complaints they had from dealerships about each specific model, but it begs the question, if it was deemed to be a problem in the S60 D5s, why was it also not deemed a problem in the same engine V70???

We bought the car in 2006 with full Volvo dealership history from a Volvo specialist garage - the car has been serviced just once by them, and they use full Volvo parts. I feel so strongly about this that I'm going to take it to court if necessary to get my money back, so the more ammunition I have the better.

Anyone else who's experienced similar problems/ had money back from Volvo for it please get in touch.

Hello all, first time poster here.
I've had my S60 D5 for just over a year now, it's done 119k miles so it's no spring chicken but I've got the starting problems described in previous posts. Funnily enough only when it's cold! I changed the glow plugs and sure enough one was defective but the problem is still there. When it starts it runs beautifully and it starts with easy start first time...can it still be the injectors? I'm not so sure.
I must add that after all these years driving all sorts it's the best car I've ever had...lovely and smooth and that engine is practically silent and 50mpg on the motorway just magic!

[D5Pilot]

Yes sure enough...two injectors faulty, 4 days of testing, re-newing and £799.02p later the car seems to be running fine. I hope that's the end of it.

[sjfinnerty]

Can anyone recommend where you can purchase the injectors other than Volvo i.e. Bosch distributor?

I have the same problem on my D5 S60 and have been quoted by Volvo €2000.00 to replace all the injectors. I'm sure that if you were to source the injectors and then find a mechanic to replace it should be a lot cheaper? I was told however that Volvo have a special tool to remove the injector, does anyone know if this is the case?

Thanks

The injectors are about £220 each and take 1.8 hours to change 5 which i work out at about £1600 inc VAT and labour at £80 an hour

You wont need all 5 injectors , one or two at the most i would say .. Volvo DO sell them singly complete with injector pipe and mounting bracket which MUST be changed with the injector ... Why are they changing all 5 ?

Volvo injectors are graded 1 2 and 3 stamped in a circle on top of your injector and they must be replaced by the same grade unless all 5 are changed then the cars ECU must be adjusted if the grade is changed . Using general BOSCH ungraded ones will cause you grief it has been talked about many times here before .

There are TWO special tools for removing the injectors but only if they are stuck which isnt likely unless the original mounting kit or copper seal washer have been re-used !

[v8disco]

I recently posted that I have changed just one injector for an ungraded Bosch aftermarket injector and it worked fine.

Based on info gleaned from this forum I suspected it would give me some problems and fully expected to have to take the Bosch one out and fit a Volvo grade 2 injector - however, it went in fine, worked perfectly and the starting problem has dissapeared.

I understand all the technical reasons why you "should" stick the with the correct graded Volvo injectors, but I wanted to find out for myself and at the time had a source of Bosch injectors at Bosch dealer prices. Maybe I was just lucky, or maybe the grading isn't quite as critical as we are led to believe.

[Clan]

good for trying , how much are they from BOSCH ?

52 plate V70 D5 auto - 99500 miles..cold start problem this AM for the first time. After about 3 mins of cranking, it started. Outside air temp around 7'C after a chilly night. Heater coil light worked as normal.

Volvo dealer quoted £250/injector plus labour.

So, taken the car to a local Volvo specialist. No fault codes showing, mechanics reckon it's an injector problem. They have quoted me £30/injector to have them checked + 1 hour labour (£52 +vat) to get them out and in. They can get any faulty injectors refurbished for £125 each with 1 yr guarantee. That sounds cheaper than Volvo!

Car is at the garage now. Should know more in the next few days. Will keep you posted.

If this works, I will give people the garage details for those that are interested. They have done work for me before and are very good. Garage is in Norfolk.

[Laney760]

Have only just read this thread

Thames Valley Electro Diesel, diesel specialists, in Reading, Berks have recently told me that they charge about a tenner each to recon the injectors in older diesels and about a hundred quid each to recon the injectors in the modern common rail engines (D5). If anyone needs their injectors looking at and is local to them it might be worth giving them a call, they can be found on the net when googled

Ok...here's a quick update. The garage phoned me today and said they confirmed the "bad starting" the next morning. So, out came all 5 injectors and off to their local "specialist" for testing. Anyway, out of the 5, he has found two unserviceable. So, had a chat with the garage and they have agreed with me for ALL 5 to be refurbished, as it's likely the others will go wrong soon too. As I am having all 5 done, I have managed to negotiate a small discount which is a help as this is not a cheap job. However, the final negotiated price is half Volvo's price and I am getting a 1 year warranty on the job too.

As mentioned before, if anyone wants the Norfolk garage details, please contact me. All work done by them so far has been to a high standard. They also provide a courtesy car for £10/day if you have to travel to get there.

I will update again when I get my car back in a couple of days time.

Hi all,

I have a 53 plate V70 and have had exactly the same problems with my engine. The starting became progressively worse during the summer (we had it checked by Volvo dealer and nothing apparently wrong, but they found things to do for which they charged us £200!) until the day we were to drive to the airport (typically) and the car wouldn't start at all. We dropped the keys in at the garage on the way through and told them to collect it, fix it and deliver it back (we were a little annoyed!).
Got a call a few days later to say that the injectors had gone and to replace with Volvo parts would be £1500 and with others £1300. I asked if Volvo would contribute and they said no.
Naturally I paid up and contacted Volvo myself who replied as follows:

Here at Volvo Customer Relations we take into different factors such as age and mileage when making a goodwill contribution on this occasion the age and mileage will effect our decision. We do put a 3 years/60,000 miles warranty in place in case any of our components should fail prematurely however once this has expired, we will look at a goodwill gesture.

However on this occasion we will be offering 0% towards the cost of this repair.

I am sorry I can be of no further assistance on this occasion.

Slightly unimpressed as you might imagine.....

Very concerned about buying another D5 (which we love...) - my question is whether there have been any reports of newer D5 engines doing the same thing? WE would be looking at a 06 plate probably as a replacement...

Any help or advice very welcome.

Hi SuffolkV70

You are just down the road from us. The Volvo specialist I take my car to is in Attleborough and are extermely helpful. If you give them a call and ask to speak to Mark, I am sure he will answer your questions ref later models, etc. By the way, I have no connections to the garage other than as a customer.

I think it's mainly 02/03 cars that seem to be "injector" affected. But once the job is done, the car should be good (injector wise) for a blinkin long time. As you say, they are a superb car and it would be a shame to change just cos a few doubts. I have done over 35,000 miles during the last year, so expect a few problems. Luckily they have been done under warranty (intercooler radiator, headlight wiper motor) but unfortunately, the injectors have gone Kaput 3 months too late. However, my cost is half what Volvo wanted, so not too disappointed.

I have recently fitted a Garmin 760 Sat Nav too with the Volvo mount. Now have my phone hands free through the car audio system plus it plays MP3 music via the car system too! On top of that I have also fitted a iO Play hands free kit, which means I can now integrate TWO mobile phones into the cars sytem PLUS my iPod via Bluetooth. All without any wires showing! Very pleased with the result. So will be keeping the car for the foreseeable future.

Touch wood!

Most comfortable car ever! Also getting around 42mpg from my automatic (and I don't hang around), which for the class of car is pretty impressive.

[palwing]

Hi..all done and dusted. Picked my car up yesterday afternoon and paid the bill. Car feels a lot smoother and seems to accelerate more quickly. However, this could be due to a "placebo" effect as I was loaned a 1.8 S40 for the time my V70 was off the road. Reasonable car, but not in the same class.

My "new" car started first turn this AM with overnight temps sub 10'C. Hot starts are as good as always.

I will now monitor fuel consumption and see if anything has changed. Will follow up with thoughts in a few weeks time.

Suffolk, I asked about later model V70's and D5 injectors. The guy reckons that they are not affected and should not be a problem as Volvo had sorted it all by then. So, looks like 02/03 models only.

Hope this helps someone in the future. My overall thoughts are that if I knew when I bought the car what I know now, I still would have bought it as it was the right price at the time. Also, it's a bloody good car with a superb engine. Now have only 150 miles to the big 100,000! I reckon with TLC it should be good for another 100k. Damn..that's tempting fate, huh?

Next car, a nice post 02/03 XC90 D5 auto?

[palwing]

Car is running sweet since the injector (x5) refurbishment and starts 1st turn even at sub zero temps. However, before the Injector problem, the computer was showing over 42mpg, but now it's showing 37.5mpg. Same sort of journeys.

Recently, I reset the computer before a long motorway run from Cornwall to Norfolk and filled the tank up to the brim. The computer showed 43.3mpg on arrival in Norfolk and I was cruising at err..cough...motorway speeds all the way. Exeter to Norwich via M5/M4/M25/M11/A11 in under 5 hrs..and I mean well under. The fuel guage was at 1/2 tank after 340 miles and the light came on after 540 miles.

However, since then the MPG shows 37.5mpg now with mixed Norfolk driving.

The car has just been serviced and they can't find any probs on the diagnostics but have replaced the fuel filter and checked the brakes, etc. New tyres have just been fitted and running at 36psi (225/45/17) Feels a little hard but I have a full boot area most of the time.

I am putting the increased fuel consumption down to the near freezing temps at the moment.

HI !

I have next problem.... On one injector i have casing worn out and they cause loud click noise other parts of this injector is in good shape :)

I buy over ebay new injector but they have different grade (Nr:1) than my original injector (Nr:2).

Now I have question: If I transfer everything whats inside of injector from original (nr2) to new one (nr1) and then install into the engine. Will they work without reprograming ecu ?

[Bernard333]

I believe it wont work even if the internal dimensions look ok the old needle will have some wear which wont match the new case and everything you read about injectors says the internal tolerances are very critical so I would discourage you from doing it but if you do decide to go ahead I would be very interested in the outcome so please tell us what happens , have you already taken one of these apart ? If you have could you post some close up photos of the parts .

[Clan]

once you dismantle an injector it will loose any grading it had and it will never go back the same, there are tiny parts in the top which can spring out and get lost resulting in a new injector needed ... If you fit the Grade 1 one you have and it works ok i would leave it like that !

<deleted by moderator> I dismount grade 2 and clean it and measurement and then mount back and work great.

[Bernard333]

Its great when someone else trys something that shouldnt work and finds it does work especially when its not me paying for the experiment , when the injectors time has come I will now have no hesitation in pulling them apart and trying to get them back together knowing that someone else did it first , ultrasonic cleaning get away , I will use a Brillo pad .

[chf]

Yep ! Injector problem diagnose on my XC90 D5 (53 reg) too and 1 faulty injector only changed today at a cost of £335. Fortunately the car was purchase less than a year ago from a volvo dealer so it was cover by the volvo care plan warranty !

Well .... a year later and the same injector #1 replaced by Volvo under warranty need replacing !!!

What is the likely of ths happening ???

Does anyone knows if Volvo fits recon injectors under their own warranty scheme ? I suspect they do as the my local indie that has no replaced the injector was told by Volvo he needed to return the faulty one otherwise the charge will be higher !!!

Sound like a rip off to me at £230+vat for an injector AND faulty pone to be returned to volvo

[Bernard333]

I agree I also think its very unlikely but garages get away with this because most normal motorists like myself dont know enough about the component to question them , I have been repairing all kinds of things that are supposed to be unrepairable without professional help and expensive equipment and once you have discovered what it is that caused the problem and worked out a way to fix it it for next to nothing there is a great deal of personal satisfaction to be had in doing it . I would be very interested to hear again from freshlo who took his injectors apart earlier in this thread now that some time has passed to see if he is still motoring with the same injectors as I am not brave enough to do this myself due to all the warnings you read about it but if someone else has got away with it then I will be willing to give the needles a polish with a brillo pad . Has anyone done a step by step guide on injector cleaning in photos something similar to the one on turbo refurb would be great ? I think that the official refurb procedure is maybe do a test on them and then replace springs and seal and do the ultrasonic clean on them and at £234 each that sounds a bit steep to me ?

[vilda hilda]

hi there, the volvo problem is not unique to the D5. I've got a 51 reg D5 that has now done 163,000 and yes starting problems. interestingly I read on the forum that one member was pouring hot water on the injectors to get it to start. A gentle warming with a heatgun resulted in that the car started easily - not very practical when out and about. The problem with common rail diesels is that the injectors are very very delicate and sensitive to the quality of the fuel.

I took the car to a bosch specialist and did a leak test (£40) which showed that one injector was leaking badly. As the car is getting on a bit I didn't fancy the relatively huge bill and working with fuel and chemicals I fancied trying a very strong fuel injector cleaner and from not starting without heating the injectors with the heatgun it now starts. I'm now down to 5 seconds when it has been standing for a couple of days and temperatures around 5 degrees C. Since first adding the fuel injector cleaner concentrate I've done 2000 miles and it is getting easier and eaiser to start.

so consensus is that it is not a mechanical failure - it is a build up of varnish which can be avoided if fuel injector cleaners are used regularely. I'm going to try another mix shortly and let you know if the progress is still positive.

when you buy your normal fuel injector cleaner they only contain 2% of active fuel injector additive (the rest is typically karosene). these normal fuel injector cleaners will not be able to clean a failing injector. the ones that I'm testing are 100% concentrate.

the car goes also much better since starting the cleaning procedure and much cheaper than changing injectors.

That woudl certainly explain why Volvo wants to have the injector back ... a bit of cleaning and then pronto a recon injector that can be re-used in any volvo that is still under manufacturer warranty !!! Nice profit for Volvo byt rather expensive for the end user !!!

What make of injector would you recommend and what sort of dilution ?

I am still not convince that I would return the faulty injector to Volvo as at £220 for a replacement, I think I earned to right to keep the faulty one ....

Anybody with experience of buying spare against returning the faulty part ?

[vilda hilda]

sorry been working too much since last posting. I'm trying a new product that is highly concentrated and now after 3000 miles the car starts fine and runs really sweet. on motorway journeys at constant 78 mph on the clock it returns 54 mpg easily. I did an injector leak test when I started this trial and will do another one in a couple of months to see what the diffference is. the problem is to find a high concentration injector cleaner on the market. If you are interested I can send you one to try (I got this from an american company to try so more tests would be excellent).

[Gouldy]

hi hilda

ive had the starting problem on my D5 S60 after just one month of ownership. I wouldnt mind trying to get my hands on some strong injector cleaner, are there any good brands in the UK?

however a friend of mine put some in his audi and apparently it destroyed the fuel filter, resulting in bits of filter entering the pump and messing up 2 injectors in the process,

I did an injector leak test when I started this trial and will do another one in a couple of months to see what the diffference is. the problem is to find a high concentration injector cleaner on the market. If you are interested I can send you one to try (I got this from an american company to try so more tests would be excellent).


can you please tell people what this magic cleaner is that you are using? you keep referring to it yet never tell anyone what it is :(

just tell us all the name and we will source it ourselves

It may be worth knowing that Volvo forbid any oil or fuel additives and any warranty claim involving engine or oil or fuel system will be rejected if they find traces of additives ..
This is for warranty of course , but i'm sure they have a very good reason for this ...

yes they do, its another way to get out of handing out money for dodgey parts (injectors) lol

Can we please have an update on your tests, as well as where this 100% concentrate can be obtained from.

Also, have any testers reported that the concentrate has damaged their cars?

He hasn't been on the forum for nearly 3 years......
It's probably Diesel Purge he's talking about and it's excellent but I've not heard of it turning a badly leaking injector into a fully functioning one.

About half of all bad injectors are just suffering from gum deposits and can be restored using a direct feed injection system cleaner. There are very few companies that I trust in terms of both producing a product that both works and does not produce long term side effects. Liqui Moly are definitely one of those companies and they make very good engine oil and fuel additives designed for dealing with specific issues. Lubriguard and B&G are also good additive companies.

I use diesel purge every time I change fuel filters, as it's easy to just top up the fuel filter housing with it (Not as efficient as using a loop to can method). I don't bother to use any other type of fuel additive as the diesel sold in Germany has enough Bio content to provide good lubricity (Effects the life of the high pressure fuel pump) and keep the fuel system clean.

Even with good quality diesel you can still get very long term gum deposits if you do a lot of short tripping, although if your car does not have to suffer such abuse there is probably no reason to use a fuel additive at all. Some additives that are added to a fuel tank will prevent gum deposits, BUT they are a lot less effective at removing them than a direct feed cleaner.
Poor quality fuel filters can easily damage a fuel injector and no fuel additive can fix that type of damage.
