Crying Shame !!
 

My V70 T5 is still available for sale @ £500. Please read my other posts concerning this t5...explains everthing i have done to try and solve the problem and codes that have come up...

My reckoning is that it will need a New Gearbox, unless you can suss out what the problem is.
Limp home mode is coming on more frequently than before.

The t5 has no other issues.

If you are coming from miles away then i would suggest a Trailer.
I have changed the PNP Switch, I have tried an ATF flush, and i have fitted a new Radiator as the old one was leaking and i thought Water may have gotton into the Gearbox......
Nothing i have done has solved the problem. Still a Flashing Red Arrow,and then limp mode.
Now as is stands i am stuck with a T5 that i cant really be driving around anymore incase i completly Knacker the car.

I do not have space or time to break this t5, I just want it gone, its doing my head by the day..

Am i asking to much money ??? Whats it worth in this state??

where about in london are u

Finchley Mate, North London just off the A406.

Cheers.

it the gear box module i would have tried reseting it cant get as it is cost for me to buy and collect

Already changed the PNP switch if thats what you mean?

Not sure if this helps but on the offchance I did a search to see if the gearbox itself has an ECU and from this it looks like it does

Have a look in your ecu box and see if you have enything like this mate, it might be your problem rather than gearbox itself.

BIG THANKS mate! Definatly take a look today...I want to keep the T5 but Ran out of ££ notes to keep feeding it !!

:thumbs_up:

Just Spoken to the guy selling the Gearbox ECU.....He could'nt tell me if i would need to download anything once i replaced it..

Any Ideas ?:thumbs_up:

Taken a look at my ECU. The one for sale on Fleabay has 5.3 on it with lots of other smaller numbers with barcodes..

Mine has 42.3 with lots of smaller numbers with barcodes that dont match the one for sale.

Does the ECU have to match up exactly the same?

Any speedy response will be much appreciated!!:thumbs_up:

Just checked my own and it is a 30.3 my one in V70 T5 CD

I would suggest you put this question in the general questions section Paddy where somebody with a bit more knowledge might be able to advise. I think there is a good chance that your ecu might be knackered.

Paddy I have found it, in Margate £20

if the engine management light is coming on, the ruff running of the engine can cause the arrow light to come on the gearbox.

so your problem might not be the gearbox or ecu, at all.

the engine has to be running right if it isnt, it will affect the auto box and it will go into limp home mode.

Have had the codes read on the car a few weeks back mate, came back with the one code saying 3rd gear out of Ratio !

Spoken to a Volvo Mechanic just, and he says the same, Defo not the ECU!
Could be Gear Selector Faulty, Speed Sensor in Gearbox, or Box completly Shagged !!

Management light was turned off a few weeks back when i had a new PNP switch put on. Two days later it came back on ?

Is your engine running ok?.....Management light is emissions!....as Les says the engine must be spot on to not effect the auto box, as it changes gear depending where the torque has moved to because of an ill-tuned engine.

If you go for the ECU at Margate his name is Gordon and i deal with him now and again and his service is bang on.

The codes will say that as it is in Limp Home Mode!!!

Just Taken th Missus to work with no Arrow Flashing...The car ran as sweet as a nut there and back (4miles) i even booted it on way back and car just took off like a T5 should..changed gear perfectly...??!!??!!

I am not a mechanic but because this fault is so clearly sporadic I would gravitate towards electrical rather than any form of mechanical fault, totally knackered gearboxes don't usually rectify themselves every so often. For the sake of a score I would try the ECU, if mine were the same code you could happily try my one but it isn't. I second what is said about Gordon he is very efficient I have bought off him and it is there next day. I too have had mechanics saying "Oh no could not be that or it is so and so" and be wrong. I threatened to sue Triangle Volvo about 20 years ago, £1300 on bits and labour for my sisters car only for it to turn out to be a broken wire in the heated seat element causing the fault!! They never had a clue and just launched into a change everything till it's cured routine. They paid up.

I hear what your saying Jim, may as well try it i suppose.

Anyways, just flew down to my mechanic to get the Management light turned off. The reader came back with just the one code..3rd Gear out of ratio once again !

Dont suppose you have a number for the guy from Margate ?

Thanks.

Just spoken to Gordon, ECU in the post !

Fingers, Legs, Everything Crossed !!

Thanks everyone for all your help.:thumbs_up:

paddy....i can bet when the engine management comes on...the arrow light will come on soon before or soon after.

it sounds to me the problem is in the engine, regardless of what the codes say for the gearbox.

if it is driving now fine, then the gearbox is fine.

it will say out of sink the code when there is a fault on the engine management side.

cos, when the eingine is "out of tune" the gearox will not change gear when it should, thus throwing up arrow limp home mode.

your engine has to be running fine.

if the codes were reset, the chances are the engine management light will come on again after a few miles. maybe 70 or 200 miles.

sound to me you need to focus on getting the engine management system right before anyting else.

also, from my experience, id maye say it is the baramoeter sensor under the bonnet, behind the headlight, on drivers side.

Will take a look mate. Whats the procedure for replacing this Sensor ?

And are they expensive to buy?

Thanks again.

If it helps, i had an M reg 850 T5 some 7 yrs ago and when i was buying it the salesman told me not to keep touching the E S W button. Have you tried cleaning yours?

unplug it, and its hlp in by one torx head screw,,,job done.
itll take appprox 2 minutes maybe less.

but to buy a new one approx £100, if you know someone with the same sensor from a car which hasnt got problems, borrow theirs for a while when the engine management light goes on. then change it.. dont bother having the engine management light reste, just drive the car and it should go out itself then you know what the problem is.

Gonna run out and clean it Now....!

Thanks.:thumbs_up:

I agree Les, that sensor is in my list of things done for a service as the ECU does not only use the actual Engine Temp Sensor under the thermostat but does also use this one you mention for ambient temps.,the info centre reading, and it makes the motor run rich if up the creek.

The thing with the engine having to be in good tune is also correct as my 960 was not changing gear very well and was quite jerky, it was due for the engine service which i thoroughly did and it sounded spot on afterwards and to my amazement when driven all the downshifting jerks had gone and the changes were back to smoothness. The gear changes also shifted position according to revs. Yes, i know it all sounds crap but when your in the seat driving and you know what your car does day in day out then anychange you notice straight away. That`s why i will always rather service the engine than change the ATF!

it seems no on is taking notice though. i told paddy ages ago

Lmason, i appreciate your help here mate, but having so many Theorys thrown in my direction does get a bit confusing for a non Mechanical minded bloke like myself.
Seen the Sensor you mentioned, and will be Trying to get my hands on one soon...First i will try the ECU, Just been out to clean underneath the handbrake where i managed to give the S E W buttons a good clean.

Was picturing your Mutt Carrier as i was cleaning away...Caked in Dog hairs and dog Flob from where the old girl i bought it from carried her Doggies all over the country !!!!!!

Only messing mate......!

Thanks again for your help, will get a Sensor and see if your Theory is correct.


:ani-red-dog: !!

re ecu.

your wasiting your money getting an ecu.

also, if you get the sensor, dont bother with a second hand one.

its best to get a new one.
also best to get genuine volvo one from rufe, rather than a pattern one.

ive had a non genuine one before and it didnt fix the problem

Whats the Sensor for Lmason?

What is its function on the car?

Thanks.

read the first few lines it tells you here

maybe do your plugs, clean dizzy cap and rotor arm as well.

the engine drives the gearbox, if the engine is not smooth, the gearbox will take the knock on effect of not changing gear when it should thus tripping the limp home mode setting.

its not a theory...ive learned this

also to get your car right, change turbo hoses replace with silicone ones, 4mm. and if the pcv box and system hasnt been done, a vacuum pipe which rund under the manifold fro the pvc box breaks with heat causing leak into manifold this making engine run ruff.

this can also cause the limp home mode on the gearbox.

you need to get to the root cause, at the moment you are just grasping at straws chaing the ecu, and guesswork.

If it were my car I'd spend £70 [Based on an hours labour here in Norwich from Holden Volvo main agents] and get the issue diagnosed by either a Volvo agent or a Volvo Specialist that way you will know if its a £100 or a £30 problem.

If this ECU doesn't sort it out and the engine management light comes back on let me know and I will loan you my barometric sensor to see if that does cure it. I will pm you my telephone number

i think your best bet is borrowing the little part , cos the dealers will charge more than the cars worth and more than likely still not fix the problem, and they wont give you money back.

having the codes read can be misleading, so in my opinion, i wouldnt bother with codes read, theres an offer on here if you could borrow that part for a couple of weeks.

forgot to mention, if the engine management light comes on before you get the chance to borrow the sensor, disconnect the battery overnight for the engine management light to go out.

but once you have fitted the borrowed sensor, do not faff about disconnectiong batteries or anything else.

otherwise youll not get rectification confirmation.

PM sent Mate.

Battery Disconected Lmason, cheers again for your help mate.:thumbs_up:

Ok, Just fitted Gearbox ECU and Barometric Sensor.

Last couple of weeks i have fitted a New PNP Switch, and Given T5 a good Manual ATF flush..

So far after doing a Razz around local area T5 is again running as it should, Changing Gear smooth, and No Flashing Poxy Red Arrow.......

I just want to say a HUGE Thanks all that have helped me out with their thoughts and comments..

If the Arrow starts Flashing again, and :snail: Mode kicks in, its off to the Knakers Yard with it !!

Got Know more money to spend.

what the status with the engine management light?

cos when they are reset, they can sometimes come on again between 100 and 200 miles.

Management light off, and so far staying off, but then again i have only covered 20 miles, so it may come back on.

Taken a look at the ATF again and still not happy with the colour, very dark.
So going to give it another Flush asap.

Off To The Knakers Yard it Goes......Give me a sensible offer its yours...........
