I have an A6 2.0 TDI. I have owned it for about 4 months. I purchased it from an Audi Specialist in Warwick. They currently accept no responsibility for the problem I have with the car.

The problem that remains relates the car when it idles. After a couple of miles running and sitting in traffic the car idles at about 8000 rpm, but every 2 or 3 seconds it appear to miss a beat and the car kind of wobbles?

Audi have ultrasonically cleaned the injectors and replaced the injector seals based on information received from Audi UK.

The car was returned with the same fault. Audi had it back for a further 4 days and were unable to diagnose the problem. The are no fault codes present. I've removed the Mass Air flow Meter plug and this has also made no difference.

Yesterday Audi arranged for the mobile technician to call and start from scratch.

He was at a loss!

These are the symptoms:

1. Erratic Idle - car wobble
2. Hesitate when pulling away
3. Revving the car through the range there is a problem at 1800 rpm
4. There is strange noise from the engine every 2 seconds
5. There is knocking when changing gear from 1st to 2nd

The technician did not rule out that the injectors may need to be completely replaced. However, he also felt that there may be something misaligned within the engine?????

Apologies if you see the same post on other forums, I really am at a loss and I don't know where to turn . If you can help or know of anyone else that can help I really appreciate it.

Many Thanks!

Thanks for replying so fast.

Where would I find the engine code?

Which sensor would you clean or replace first? Others have mentioned the the clutch fly wheel?

Slight typo above should read 800

My car is a 2.0TDI 140 BHP manual

Dealer is now has diagnosed the problem as the Dual Mass Flywheel. The work is being carried on Tuesday at a cost of £1300.

Fingers crossed???

Dual Mass Flywheel replaced and it's made no difference. Although the dealer insists it needed replacing?

Back to dealer and they now think it's a faulty injector (which have been cleaned). Previous owner may put petrol in the car?

What do I do about of money I've spent?

Dealer said there will be a cost to get the injector tested???????????

Update!

Hi Guys,

This draws to a close. I returned the car on the 5th October.

The Master Technician called and told me he was convinced it was a EGR fault and he was waiting for an CD update from Audi. The update arrived on Tuesday and you guessed it! It didn't cure the fault.

Plan B - remove the injectors and send them for testing (they were cleaned 3 months ago).

On Thursday, I received conformation that one of the injectors was faulty. I agreed for it to be replaced at a reduced cost of £365. I was not changed for removal and testing. I have now spent nearly £2,000.

The Garage are fitted the injector Friday and they plan to keep the car for a further 3 days in order to carry out a comprehensive road test.

My next port of call is to initiate court proceedings against the Garage, I purchased the car from.

He has asked me for a copy of the invoices in order to consult with his insurers? I think he thought I had not carried out any work on the vehicle?

It gets worse !!

Picked the car and paid £365 - drove it home and it's still the same in fact it might be worse! Car goes back on the 26th for the 6th time!

I will be contacting Audi UK when the car is in situ unless anyone else has any advice?
