hi
New to this site and seeking some help and advise please
I have a 2005 a4 2.0 turbo quattro sline tfsi
It has been on audi diagnostics and is showing no faults codes yet is stuck in limp mode. The garage the looked at it is an audi approved and only does vag related work. only fault on diagnostics is when pluged in and ignition off and accelarater pedal pushed to floor it reads 99% however when ignition on and pedal pushed to floor it reads 12% thus stuck in limp mode. Only other problem they found was a noisy in tank fuel pump but fuel presure at engine is correct. As a bit of a technician myself in the trade i carnt see the noisy fuel pump as the issue. I am thinking throtle position sensor or mass air flow but surely these should throw up fault codes. Any advise welcome
