Hi Guy's,

Newbie to the forum. Ive got an A3 2.0TFSI Quattro on a 2006 plate. I had a stage 2 remap about 4 month ago and over the past 6 weeks ive noticed that when the car is driven from cold to say work its fine. But if i return and then try to drive it before its cooled down, i have no power. It's as if the throttle is stuck and you have to really rev the engine to try and clear it. This keeps happening untill you let the car cool down.
Ive changed the Piston Diverter Valve to a new OEM 2.0T Upgraded Piston Diverter Valve from Awsome GTI to no avale. Can anyone help? :1zhelp:

look on the inlet manifold,there is a breather valve which has as small flap inside
The flap dislodges and allows manifold pressure to leak into the rocker cover without a fault code
Also disconnect the fuel pressuree sender and re try as these are problematic on the fsi engines
scan for fault codes and post
