Re: harsh idle with air conditioner on? (Jeddah1.8t)

Each model car has a diff. AC compressor. Some are larger than others, some engines obviously have more power.
The 1.8 is a small engine /w little power when at idle. Most cars idle slightly rough /w the AC on. It's also an electrical load.
I bet pulling up on 2 or more window switches at idle has the same effect.
Its normal, and will only get worse as the car/alternator age.

Check your tach and see your RPM at idle, if it is below 750 RPM (and it sounds like) you might want to raise the RPM, find someone with VAG-COM and he/she will do it for you.

Re: harsh idle with air conditioner on? (20V1.8Tnut)

I heard about the VAG setupo, I purposefully like to keep AC off for this reason (rough idle and general engine coarseness)
