I just pick up my car from mechanic. Passat 2.0 tdi 140 bhp. Problem was Manifold Flap V157 no signal ( 19558 ). He replaced EGR valve, clean the throttle, deleted engine and emission lights and everything was fine. I got in to the car turn engine on and off and the light is still on:banghead: Mechanic is going to check everything again on Monday any idea what the problem is ?
