Hi! I'm new here and need some help. So i bought my beetle in the fall, used. And quickly after buying it I realized that whoever owned it before me did not give a single **** about maintaining it. One of the things I wanted to fix recently was the AC not being cold, so I charged it. It was at 5 PSI, charged it to about 40, and it was great. Compressor ran great, air was cold, perfect for the summer. But now, when I click on the AC, the compressor just surges on and off, revving the RPMs every time it comes on, and the air isn't cold.
So I did some research, and I was seeing a lot of stuff about carbon build up in the system. Specific potential causes for my issue were:

• idle air control valve
• throttle body
• EGR valve
• clean the intake manifold

Can someone please let me know what the best route of action to take to fix this on these engines would be? And if it is to clean the intake manifold, can you please explain in ridiculous detail how I'm supposed to get to the god forsaken thing? Thanks so much :,))

First, what year, model, engine and trans VwWare you working with?

Also, a good first step; would be to scan for trouble codes and post any you find.

I also have a check engine light (P1127 long term fuel trim B-1 system too rich) idk if that could affect it in any way. I have a brand new MAF sensor and engine air filter in as well

Welcome, to the site; I am responding on your questions, at the other 1.8T discussion area thread. In the future, please; try to keep single threads, for the specific topic in the appropriate discussion area and avoid, cross posting. Thanks.

CCOT (Cycling Clutch Orifice Tube) Aircons need to be charged with the correct quantity of gas, within +/- 50 Grams of specifications Not topped up and hope for the best. These systems will cycle the clutch on/off with an incorrect quantity of gas. Take it to a qualified Authorised AC tech
