Hi all

I have a 52 Passat Diesel done 180,000 miles that went in to the garage with running on three cylinders and noisy. Now that is fixed and was due to the cam shaft worn.

The problem that exists now is, it runs okay and sound good, but has very poor acceleration, and judders at 2000 revs. It will drive okay when cruising at 80 mph.

Now the garage is stumped it has NO fault codes and had 2 types if compter checking, it has had a service as well new glow plugs, new fuel pipes the fuel filters all ok. new fuel pump, duel mass flywheel changed and it still has no acceleration. It drives like and old type diesel.

This car should have 130 bhp, the borrowed nissan micro accelerates faster.

Please help it been 5 weeks now and my friends want their car back.

Hi Debbie!

Welcome to TSN

Blimey! That's not good.

The garage you've tried it with - is it a VW dealer or VAG Specialist?

Sounds more like a sensor has gone. Which one? Crank Sensor? dunno.

What fuel do you use? Have you tried injector cleaner too - as now you have one clean one and 3 dirty old jobs. Get some Millers in the tank.

Maybe Shark could help suggest a few bits?

Hi Cruiser

thank you for helping.

The Car is at a good VW garage, no it is not a VW dealer or VAG specialist, he is an independant and a good one. this is causing him some grief!!

He sent it to a VAG garage and they said to change the duel mass flywheel, which he has done with no change to the performance of the car.

I think he may send it back VAG for more investigation.

I will tell him any help that this site will give as i think he wants the car out of his garage as much as i want it back to drive.

Many thanks

Desperate Debbie!!!!!!!

hi debbie if i was you i would tell the garage to check out the turbo eg the boost and all the vac lines for leaks or not connected also make sure that the actuator on the turbo is not sticking as the vanes my be stuck and putting the car into limp mode

hope this helps

Thanks for your help steve. I have spoken again to the garage again. He is going to do a compression test, then if that has no results then he is going to do a injector test.

Everything that he has done has just not resolved the poor performance. :ffs:

If a sensor has gone wouldn't it show up on the computers he has plug the car into. I'm told that he has the newest diagnosic laptop that shows what the car should do and what the car is doing. He has even had a independant fault finder/ trouble shooter spend half a day driving it about, with not solution. This is why I'm here, hoping for a miracle:).

Maybe I got one of those car you park on the drive and polish but just don't drive it!!!

hi, have you tried an EGR valve, if the car is recurculating to much exhaust gas it will accelerate poorly but cruise ok..

hope this helps

hi debbie snowdonc could be right and the egr valve could be faulty they could try blanking it off and see if the car preforms better still think that the lack of power could be down to a turbo problem although the garage should see some boost fault logged in the memory

are they using vagcom? may be better if you let a vw dealer look at it with their software

could also be something silly like a blocked up cat or exhaust box

Hi snowdon and vwsteve

I know he took the exhaust off completely and ran it without with no change in the performance. He will try this after he completes the compression test, which will hopefully get done tommorow.

Fingers crossed and pray!!!!!!!!

As to the VW dealer I would hope that they would of done that when it went in, for diagnostics a few weeks ago, they had the car for two days!! It came back with dual mass flywheel problem and which was incorrect. Unfortunatly I have lost faith in VW dealers over the years.

More news on friday late afternoon, lets hope its good!!

+VAT 72.02 +113.93 +294.32

total cost £3274.24

the car went in misfire running on 3 cylinders and a service

the camshaft was the first problem as the head was sent away for reconditioning and it was all put back together and was running like an old diesel.

trouble shotter came and drove the car around plugged into pc totry and find fault on luck. sent to vag in kings lynn spent a few days there came back its the fly wheel and mec. didn't believe this so had the head off a second time and replace the cam. No luck so i okayed the flywheel believing it would sovle the problem NO LUCK.

Mec. compression tests the car comes back to be poor on all cylinders,

so i pay the bill and say no more money.

he said will fix compression prob only charge me the parts so no more than £100.

Now i am told that thew injectors are faulty and only working slightly, well enough to runn the car.

but its going to cost me another £800

I will not pay anymore and asked to have the car back will faulty injectors.

question

on the bill has injector kit and the recon head does this mean that it should work with all that work done on it?:confused::confused:

Feck!

So the fault is still there and you have paid out a lot of money?

I'd go to them and say you want a refund, as they have not fixed the fault. You should not pay for the bits they replaced that did not work/fix the fault ie the 'new' injectors.

Also, ask them if they have replaced the injecotr pump..... my friends PD Golf had a judder only when cold. Turned out injecotr 2 and the pump where knackered. But she puts in any old diesel fuel - I only use Sainsbury's/Shell/BP, as you know the quality is good.

Did you get the Millers Diesel plus injector cleaner stuff too?

Have they actually cleaned the EGR? What does/did the VAG-Com/VW computer report back when plugging it in?

Also, is the car at a VAG 'specialist' or the VW dealer?

Is the car manual or auto?

hi debbie sorry to hear that your cars not fixed sounds to me like the garage where you have taken it hasn`t got a clue you could have had a good secondhand engine fitted for half what you are expected to pay i wouldn`t pay and tell the garage that you will take them to small claims court if they insist on all the money

going back to your probs if the compresions are low then its either a bore or pistons problem or cylinder head/valve problem any good mechanic should know this

hope you get things sorted let us all know how you get on

Thank you :):)for your comments the garage is an independant.

The car went to a VAG dealer for a few days at the start of all this, but they came back with the flywheel problem.

I should of demanded to know what the bill was before the flywheel was fitted.

I haven't seen the report from the VAG dealer and don't even know if they plugged it in to a computer.

I have told the garage no more money and i will take the car back as is, so p****** off with whole saga. He has now promised to fix the car at his cost, he doesn't want me to drive the car as it is.

I just want my car back and the whole situation to end. :(:(:(

This has all been guess work i think now.

The bottom part of the engine has now been over hauled as well as the top. but it still not working.

Now It is believed to be the injectors. :ffs: Which is what the first thought was but the computer was telling them that it was all running okay and that was the new VAG/Audi laptop.

I think too much reliance is on what the computer is tell these mechanics!!

I'm not convinced that even its the injectors.

its a manual diesel, i have not had the car back yet.

The garage have now done the valves and pistons which has now lead them to the injectors because they did the valves and pistons obviously road tested it, and moved on to the injectors before informing me this is what was happening.

there is not much left to change on the engine, but i'm not paying anymore money and i hope to have it back home by the end of the month because the more i discuss it the more mad i am becoming. It takes a lot for me to lose my temper!!

I have had it back now for a few months, after all this i had to have replacement recon injectors. Well its running and i have done a gentle 1000 miles to run the new parts in.

Although garage advise to put some injector cleaner in it. After all that work as well!!!!!!!!!!!

I will do this as advised above.

This has been the first most unlucky car i have owned so far and hopefully the last.:o

Now have noise which i think is the power steering pump.

see new thread Squeaking when steerings on full lock!

Thanks for the advice.
