Hi all, I hope you can help I have just bough a 2001 a3 1.9 TDI, the issue i have is that the car goes into Limp mode at around 3000 RPM reguarly and i cant figure out why? i have also used almost a quater of a tank of fuel and i have only done 40 miles on very sensible driving! I have previous tickets for work done and the Mass airflow was replaced in 2005 due to "Poor Performance"?? I had a friend look at it and he found some small pipes (part of the Vac in/out) had holes in them and these were replaced but the problem persists :/ When i started the car this morning it really struggled (Its cold and been snowing) and snorted a big puff of white smoke when it did start. i had read somewhere that the turbo may be leaking? I have a code reader on its way so should be here this week for more info. Can anyone shed any light on this in the meantime??
