Turbo overboost & limp mode
Audi A3 2.0 TDi, 2003 onwards
Hi all, new to the site so please excuse me if I am covering old ground but I am desperate!
The problem I have is I am driving along ok, then suddenly no acceleration at all and the car is in limp mode and only works temporarily if you switch the engine off and on but only for a little while. This now happens all the time. The EML came on until it was cleared by the AA man the last time.
I have just had a full diagnostic at Amersham Audi, faults detected are:
P0234 (charge air pressure control limit surpassed, short time fault)
P1950 (radiator fan-V& not moving freely/blocked)
P1951 (radiator fan -V177 not moving freely blocked).
00003 Dash panel insert (control unit defective)
10 faults detected on the electrical system, all to do with sporadic electrical fault in circuit (I have replaced 2 rear offside brake light bulbs in 4 years)
They have quoted me £2000 for a replacement Turbo! Do you think this is the problem or are the dealerships trying it on, especially as I am a girl? I have read on this site that alot of people have had similar problems. Should a turbo go after 4 years? Also, I do alot of motor way driving so it gets a good run all the time but I don't spank it!
Has anyone had a reconditioned turbo fitted or can recommend anyone in the Watford/Hertfordshire area?
I would really appreciate any help/advice!
