Hi guys,

My car seems to go into limp mode after 60 MPH, not sure why.

I have changed a boost control sensor but that did not fix my issue.

The fault code present after a VCDS scan is shown below.

Possibly sticky veins in the turbo. There a product called revive that has got good reviews

Just an update, had a garage take a look and changing the sensor made no difference so they think it is the turbo actuator
Hi bought my audi a3 2ltr tdi 4 weeks ago .been havin the same problems sometimes it will go into limp mode at 65mph or over 80mph then have to reset really annoyin .keeps comin up with turbo over boost on diagnostics test.a fella wreckons it could be map sensor but been reading about other people havin the same problem they had the sensor replaced and was only getting 50 miles an it would go into limp mode again .av read so many about replacing the actuator that it resolves the problem can anyone agree with that please..had the car in for full service to find it hadnt been done in a very long time also been puttin only vpower in from shell as made a slight difference as i wont go anywere else for my diesel now apart from shell .added wynns turbo cleaner to it as well yesterday to see if that will help with the problems .would anyone reccomend revive as the reviews on that one r really good ??
Fella at the garage didnt giv me the code just told me that my turbo was over boosting .will fimd out tomorrow an will let u know
Haven't used it personally but heard good things try it and a tank of vpower
