Faulty turbo.Refuse to repair . Mis-sold.

Hmm. technically its not a 'fault' as the turbo is otherwise working correctly. I had a BMW that did that for several years.

Ultimately it'll be that a tiny piece has broken off one of the turbo blades.

I would be pushing for it to be fixed though.

It's not really about slowing down as much as cooling down. If the oil supply to a turbo is cut (engine off) when it's very hot, the heat will damage the bearings. Drive with low revs and little throttle for the the last couple of minutes of a journey and the turbo gets a chance to cool to a decent temperature before you stop the engine and cut the oil supply.

Do that and you'll save money in the long run (back to money saving )

On high performance cars that will help prevent bearing trouble in the turbo which would stop the turbo ultimately breaking up.

This isnt what that is though - its a turbo vane problem, not a turbo bearing problem.

What most people don't realise is that you need to leave the engine running for 30 seconds or so after you've been driving in the range the turbo has been used in order for it to cool down. Many people get to the end of a journey and then just turn off the engine. That causes premature wear in turbos as the oil circulating and cooling it is no longer doing that.

I don't always drive like Miss Daisy for the last couple of minutes of a journey, hence I fitted a turbo timer on the basis that £60 odd spent now will save me £500 + in a year or so's time

Cheers for all the tips on driving a diesel and the VAG good /bad debates.

Took it upon myself to visit the Audi dealership to see if it had been there and checked.

Guess what. It hadnt. No record on their system

Is it booked in for next week as arranged ?

No,nothing booked here.

Set off to dealers in a calm ,reasonable state.Yeah right

Asked if it had been to audi .Yes was the reply .But ive just been myself .

Backpedal time do you want to meet the bloke who took it.Why should i believe him your all liars

Is it booked in for next Weds? Yes .
But its not according to Audi .Please check.
Oh no its not

The set of lying,decitful ,dishonest b******S

Booked in with Audi for two weeks and im taking it and waiting with it


Hope Audi are unhappy that a dealership is using their name and reputation to convince customers to buy potentially fualty cars

It's a common problem on any car with a turbo (not just VAGs, not just diesels) - they don't last forever.

My '98 A4 was still going strong at 140,000. My '97 Merc is the same at 240,000.

Turbos can last a very long time.

This may help premature wear to the bearings of the turbo, but that is not the problem here. This is wear on the turbo vane which could have been caused by the tiniest particle of grit in the air hitting the end of a turbo vane and chipping it.

The scenario you are talking about is more prevalent on high performance cars, and this issue being that your turbo may be spinning down from some really high RPM and when you turn the car off your oil pump stops so it no longer gets oil.

If you have been driving any car at a reasonable turn of speed then stopping suddenly it is good practice to give the engine a little time to recover before switching off, irrespective of having a turbo or not.
