fed up with a4 problems

[saif786]

hi all.had a number of problems with my 56 plate 2.0tdi a4.one problem that was resolved before seems to have reared its ugly head again.driving down the motorway and car goes into limp mode,coil light starts flashing and car wont go above 50mph.after pulling over and switching engine off for a minute and restarting,the lights gone off and car driving ok..some 50 miles later same thing again.prior to that the car hesitating intermittently for about 2 months.took it audi and they technician jumped in car with me and went for a spin.he said it was just the dpf filter and because I did mostly local mileage I needed to drive car on motorway so it can clear itself.i have tried everything but still same.anybody can help out there plz.am seriously considering getting rid of car and staying well away from audi in the future.the car has only done 77k.always serviced well on time with genuine audi parts and still problems.

Scan for faults and post the codes.

I would suspect your problem is overboost, which is a sign of a coked up turbo.
We need the codes to confirm.

Sounds like a Snap On - Solus/Modis - They're usually pretty good for diagnosing - like Chris says though, might be wise to have someone scan it with VCDS
