Hey all, ive noticed in the last couple of days with my auto td5 that when I have my aircon on and I stop at a set of lights it idles rough, if I turn it off it seems to be ok, ive checked the nanocom and no faults are logged, anyone wanna point me in the right direction

Check the wiring around the front of the engine the two
Pclips can rub through the insulation,
Rub points for wiring around AC pump.

This wiring is for the AC AAP MAF engine temp
and wastegate modulator.

So a short to earth or live can effect the ECM
If modulator earths it will open.

This is how I realised my MAF was dead. That and slightly unpredictable on the auto lock up as well.
