my 2001 a4 1.9tdi sport recently started to go into what i thought was limp home mode,but now im not so sure,at first the car was going from being ok to having no pull at all,and it was flipping from the two at random times,either when engine was cold or hot,and not just uphill but on straights too,the turbo would kick in and it flew as normal,then next second it was flat like driving with handbrake on,it wouldnt rev past 3000rpm and was poo!,hence limp home mode was my first thought,ive since changed the N75 valve(from Audi not Ebay),and ive ran with the MAF disconnected(no change),ive checked the hoses i can see for splits or tears,but i think there is still a few to check but cant see?,this started a few days ago and over the last two days the turbo has no kicked in at all now,im at a loss and im reluctant to take it to a garage as ive only got a few pennies spare at the mo!,it is due a sevice and the service parts are coming in the next few days,but im sure this wouldnt be the solution,it also gets up to normal temp(90) and runs fine,except no boost!
ive had it on the plug in for codes and none come up except engine mount!
anyone near me(middlesbrough) that could help a guy out?
Pretty sure the unplugging the MAF trick doesn't work on Audi TDI's so I don't think that's telling you anything. Have you had a look at the measuring blocks on VCDS/Vagcom yet?
