I have an idle problem with my 2000 Polo 1.4 16v, when the A/C is on the idle drops to zero and stalls. This happens at lights and junctions, seems to idle ok when A/C is off. Any help would be gratefully received.

Hi welcome to the forum
I'd be looking for a vac leak, fairly common with older cars. With all those years the lines would be dry and break easily.

Run the engine pop the bonnet and you might be lucky and hear the leak or even feel it by moving your hand around the engine bay, start near the throttle body.
If that does not resolve show anything a proper VCDS scan might shed some light on it or a smoke test would be another option.
