As per post title, turning on the AC seems to draw a big chunk of engine power / feels like driving with handbrake on...
in fact it seems to cycle on and off every minute or so
not sure if this is normal on cars this old -
had a hire car last week and AC made hardly any difference to engine performance
had new aux belts fitted few months ago but it made no change
is there any way to check correct function through VagCom?
98 TDi btw.
