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 :,))
