I just replaced the compressor, which turned out to not be the issue at all as it is still not blowing cold on the highway. Not even the dealer ship can diagnose the problem. My guess, it has a high pressure vacuum leak. But I'm just here for another opinion. The car only has 40k on it and it's the SE model.

Two service dealers can't find problem. Sounds like an oil can popping or something expanding on a hot day. But notice it when I'm turning the steering wheel. Any ideas? Thanks!

Can I use regular fuel instead of premium on my 2014 Tiguan?
