Loss of power and will not rev over 3000

[Dave tonks]

Hello to everyone out there in volvo land I wonder if there's anyone out there who can help me with my problem. I have a Volvo S80 D5 2002 with 124000 miles on the clock and what a wonderful car but recently i've experienced a loss of power not all the time and it will come on at various times but mainly under hard acceleration. then it appears to go into a like limp home mode and will not rev past 3000 rpm but will still maintain speed if i accelerate gentle, i'm not sure if this has any bearing on the problem but it is due its service and the sevice indicator lights up when you first start the car and stays on for a couple of minutes. this is an imtermitante problem and appears to reset itself once i,ve turned off the car and allowed it to cool down. I am at a Loss and as yet haven't taken it to the garage because I know volvo will want to empty my bank for me and that you fine people my have the answer for me

My 03 V70 D5 had similar problem at around same miles starting over a year ago , went on until January this year and even today still dont really know what caused it , loads of people have had similar problem but I couldnt say they were all the same cause . Things you can check yourself are : maf plug connection , on mine I unplugged it and had a short test drive then plugged it back in after a few miles and have not had a repeat of the problem since . You could also check the turbo inlet rubber pipe for split ( see hobbyhorse post for a guide and set of photos ) . Checking for fault codes on mine did not give anything which I suppose could be due to the intermittant nature of it but I still dont understand why no fault codes were stored as the problem went on for a long period and got the message ' engine sytem service urgent ' on the dim a large number of times . A split or soft rubber inlet hose maybe would only collapse at a certain vacuum when accelerating hard so this could be intermittant . Less likely but possible would be intercooler or other rubber hoses which after the turbo have pressure in them when the turbo is boosting so will bulge outwards , again loads of posts on how to check these on the forum . In addition you could have the beginnings of a failing electric fuel pump , these do fail intermittantly and I had this problem on mine , this eventually caused the car to break down unable to start until it was replaced and me thinking that had cured the power loss problem but not so . If it does turn out to be one of these problems you can fix it yourself at very little cost .

I've had exactly the same problem appear in the last week or so. I took it to my local 'fixer' and he's found that the intercooler has a crack in it so now I'm on the lookout for a replacement - anybody have one for sale?!!

[ads001]

I've just had similar symptoms. My C70 D5 went for the third year service the other week, shortly afterwards the engine service light started to come on, I put it down to coincidence and took the car back to have it reset. They did this but it has happened again, it's due to go back next week.
Whether this is related to the service light I don't know but occasionaly when say doing 50 or 60 I floor the accelerator nothing happens no increase in rpm or speed, if I leave it a few seconds and try to accelerate again it seems fine.
I will ask the dealer to take a look when it goes in on Wednesday but if anyone has any suggestions I can check before then or ask the dealer to check it would be appreciated.

My V50 E4 2.0D exhibits almost the same symptom with the exception of service light coming on.

It occasionally will not rev beyond 2800rpm, with normal feel and acceleration to about 2000 revs, but sluggish with only very slow acceleration beyond.

Turning off and then restarting engine after a minute or so will normally cure and car will drive perfectly normal after.

With my car this has been diagnosed as DPF differential sensor in the past, with sensor being replaced and car being fine afterwards.

More recently, problem has come back intermitttantly and may not show for weeks or months.

NOw I know that 2 ltr ford engines (used in V50) are significantly different than true Volvo D5, with regards particulate filter design, but I wonder if there has to be some kind of regeneration taking pace on the D5, without the aid of fuel additive as used on the V50 engine.

If so, maybe the sensing device, or regeneration control system may be at fault, albeit intermittantly.

I certainly think that a trip to the local dealer will perhaps be worthwhile, even if it's only to get the codes read - unless you can do this yourself of course. I'd at least ask the question of how the system keeps itself clean. ie does any form of DPF regeneration has to occurr on the D5, even though no additive is used.

Remember that V50 engine has a replaceable DPF that has to use additive to increase temperature so that under regeneration, all the soot is burnt off. With the D5, I assume that this soot still has to be got rid of but without the aid of additive to increase temp.

Let us know how you get on.

First thing I'd check would be turbo inlet pipe for split or softness mine was well knackered and I never knew but can cause symptoms like all have stated good luck

[Taf63]

Yep no joy - garage replaced the intercooler, tested the car and couldn't find a problem. Predictably accelarating hard on the way home caused the 'Engine Service Required' warning to come on. In addition to this I started the car the following day and was had a warning to stop the engine because the coolant level was low. I hate coincidences and was thinking maybe the garage had done something to the radiator.

Took it back to the garage, they run the car for a while to warm it up and apparently no leaks. They then 'thrashed' the car and no fault message. You've guessed it - drive it home (hard) and the'Engine Service Required' warning reappears........aaargh!

So now I'm keeping an eye on coolant and am wary of overtaking anything until I can get it back in the garage. Thanks to Jiffy176 for answering on another thread - I'll get them to check the turbo inlet pipe to see if it's got a hole or needs replacing.

[ads001]

Mines ok now, the Garage had the car and initially said it might be a pressure switch but in the end all they did was a software upgrade.

[dipstickone]

had this a couple of times on v50 d5 - put down to "sensor" problem.

[robdavis7906]

i have this same problem obd code p0244 exhaust wastegate solenoid a range performance anyone know where this solenoid is on an 2004 s60

many thanks

[gazmcgaz]

hi all a newbie here.
i have a 2002 s60 d5 with 130000 miles on the clock and this has happened to me a couple of times.
turn the key off and it seems ok again.
on my car i have a problem with black soot from the exhaust so i disconected the maf wire at the air filter box to see if it cleared it only to find it would not rev above 3000 rpm.
so you might have the maf sensor playing up.
hope this helps,gaz.

[Chris Parish]

My S80 D5 2002 did similar to this. It was the turbo inlet pipe gone soft or split, I'm not sure. It ran perfectly until you put your foot down and then above about 3000rpm it faultered badly.

[flying.man]

Have you tried disconnecting the MAF sensor?
On another make of car i had if you did this and it revved ok, then didn't when connected this would indicate a fault on this part! But with egr valve sometimes clog up if the engine has not been worked hard enough! (ie driven too gently)
Best of luck

[tykey]

Mine did the same a few times, no fault message but corrected itself if I restarted.

can't be sure if this actually fixed it, but I fitted a new fuel filter and it hasn't happened for a few months.

[Djole]

Depressingly I have had the same problem and today my local Volvo Garage tells me that the EGR valve is faulty and needs replacing together with a cooler valve and electric motor. Price quoted is an eye watering £999.00 !!! I live in Sheffield and my car is a V70D5 2006 Model!! How common is this problem? Is it worth getting second hand parts to reduce this price and get my local independent to fit?

[thebigyin]

Hi, my 03 plate V70 D5 was experiencing the same symptoms and going into limp home mode. An independent Volvo specialist diagnosed the problem as the air mass meter. It has been replaced, and so far (fingers crossed) the problem has not recurred. Total cost inc. VAT - £290. Well chuffed.

[BillB]

Get the codes read. Assuming the i/c pipe is intact my money is on the MAF sensor - when this is on the way out you'll experience significant loss of performance, especially when climbing. The service light is irrelevant - it is reminding you a service is due because 10000 miles have elapsed (or so many engine hours). Regards.

[mmax]

In S60, S80 and V70 is fitted engine mount witch vacuum suport. If is any problem with the vacuum (split pipe or mount etc... ) that cause the loss of power without fault codes.

worth to check

Please found the local garage with volvo knowledge, no cowboys !!!

I drove through a flood water went into air intake system and soaked the air filter preventing the car from even starting. so I removed air filter same problem wouldn't start dried out best i could put back in, car started but wouldn't rev above 3000rpm this is a safety mode that will reset itself once fault no longer detected replaced my air filter with new one took out still wet muddy old one and hey presto runs fine so to me the obdvious fault with yours is something to do with the intake system a break in pipe blocked inlet hope this helps

[Papa Lazarous]

This is the Particulate Filter which usually causes this issue. Designed to lowere emissions, however if blocked then will cause the Volvo (like my V50- 08 deisel) to rev just shy of 3000 revs and not beyond. REstart of the engine normally clears this, however regular long dirving on motorways is recomended. I just got mine back from service having experienced this issue and was advised that there is a resevoir within the vehicle that needs topping up, and mine had not been done for some time! I will now see if the issue returns.....also worth noting i never had a warning light etc.

2006 V50 D5 124K AUTO -

Thought id bring this thread to the fore again as my car has very similar issues. Recently purchase which im relatively pleased with.

Had a volvo free health check done and was happy to find that i was advised to change front/rear pads & disc along with the brake fluid.

However whilst driving along between 1-2 revs i find the engine quite hoarse and loud.
If i wanted to try an overtaking procedure, and floor the gas pedal i would have to forget it as the revs go up fast enough but doesn't ever go past 3k.

Up to this point if im driving along at say between 60-80 the engine decibels are very low.

Unfortunately restarting the car and going through the same process makes no difference to the revs.

The rev issue prompted me to get 2 diagnostic checks, and both readings come up with air flow sensor and egr valve sensor.

Which one of these should i look to replace first or should i try to clean the air flow sensor/egr valve first?

If it is the particulate filter causing this would it not get picked up in the diagnostic check?

The car has had full volvo service history up to 90k then bmw specialist servicing up to the existing mileage.

So it looks likely that the issues could be one of

1, DPF - possibly clogged up
2, Air flow sensor
3, Egr valve - however this was removed and cleaned last year ( have a bill)

Which one should i get checked out first?

Many thanks
