We test drove a used 2006 325i bmw that had 80k and while driving the car it would jerk when at idle - only when the AC was on. This is what the dealership had to say:
Its the air compressor turning on and off. When the set temp is reached, it deactivates the ac compressor, and when temp drops-turns ac compressor back on. This causes a load on the engine since the compressor is driven by the belts of the main crankshaft. So when ac compressor turns on, it puts a load on the engine and that is what your feeling.

To heck with that dealer. Car is made to cover the load and maintain idle. Vehicle is either way overcharged to cover a problem or if not now probably has a seizing compressor,

It may be a leaker and dealer may have overcharged it just to let it leak down and work and you can't get away with that as compressor could be choking on liquid when it should be vapor.
Can't say much for sure on this and no telling who has done what? Big bucks to fix A/C so if not purchased yet pass on that car. Could be that engine can't compensate for the load and be another huge buck problem??

Your reply says it all - you don't know Jack and should have anything that moves fixed by a pro! Nuff said,
