Hi, My daughter's A1 1.6tdi has started dropping into limp mode. I have removed and cleaned the EGR valve and MAF sensor which has improved things slightly. However, when the engine is warm and I attempt to accelerate above around 3000rpm it drops into limp mode again. It does reset by stopping and restarting the engine. I would greatly appreciate any advice on how to fix this issue before having to swapping out expensive bits of the engine in an attempt to fix. Thanks.
