You should probably post this a new thread, you'll get more responses. Is the compressor spinning when it is on? If so, the compressor is bad...MarkMy 2010 TDI Jetta AC will not cool pressure is 30 on the low side and 27.5 on the hi side with ac on ,engine running .
What should the pressure be?
I have Ross Tech Micro-can and it shows no fault codes in the AC
