Could well be mate.
It was working fine then, out of the blue, it started stalling.
Engine hot or cold, same thing.
What I'd like to know is where do the wires from the P8 ecu that are shown on Bigturbo's web page go?
Pin 21 and 11, What signal and were does it go to? Relè? Idle valve circuit?
I've raised the engine idle using the idle adjustment screw, by raising the idle it just about holds 750/800rpm with the compressor engaged but then the hot idle with the compressor off is 1100 rpm..
