Idling issues Audi A3 8P

[Shram]

Hi, I've had this weird idling issue for about 2 weeks now, hasnt really changed in the 2 weeks. The revs when idle jump around from 1000rpm to 750-800rpm, almost as if im tapping the throttle pedal. I've googled the problem and it seems it could be a vacuum leak of some sort, im not too sure. Any help would be great. I have videos of the issue if it helps more, cant upload on here. Thanks.

You did not say what engine you have? Could be vaacum leak but if it is CR diesel it often can be regulator on hpfp.
