2007 A3 2.0 TDI 170 - Turbo failed AGAIN after 20k

[cjensen25]

Hi, I'm really hoping somebody can help me / give some good advice. I'm not very mechanical minded in anyway, so please explain in laymen terms.

My A3 currently has 140,000 on the clock. It was previously a company lease car, I bought it with 100k on the clock.

I had a turbo replaced at 120k, then had the new injectors done via Audi recall at around 125k. I've had numerous problems with the DPF so I drive it hard around 3,000 revs to get it warmed up and eventually sorts it. It STILL has the same DPF fitted as when manufactured.

The turbo blew again! I sent the turbo to AET Turbos (they seem to have good reviews) and they mention it was down to carbon build up, the exact words was "defiantly an engine problem" and advised to check the sump for oil quality.

Has anybody had any similar problems? Could the DPF be the root of the problem?

Many thanks

If I was you, I'd consider a dpf removal & map to suit & fit another turbo, dpf would be expensive to replace.

Just a quick update: They got the sump off today and found a small amount of gloopy carbonated oil but I've been told nothing major.

I've had a quote from a garage of around £370 to have the DPF removed and ECU DPF Delete -does this sound about right?

you should change the oil feed pipe and renew the oil and filter when changing the turbo

Seems a fair price for dpf removal etc.

Doesn't new MOT requirement say that original emissions control equipment must remain on the car?

Thats uncanny as there have been allot of dpf removal discussions on another forum I frequent & I can see this being a problem come mot time & also thought the same.
