Our 2011 Jetta (4 door sedan) started having poor air conditioning late last summer. We assumed it needed a freon charge although was confusing as it seemed intermittent. We didn't bother getting it charged until after winter passed so had it charged this spring. But at that time we also started noticing some weirdness with the outside air temp sensor. It was intermittently erratic, working correctly some days but on other days showing wildly erroneous readings (usually ready way way colder than what it was outside). The AC charge didn't resolve the issue.
Eventually a clear pattern emerged - when the outside air temp display started reading very low then the AC output significantly declined. And now the radiator fan is on all time too. Is there some connection between the sensor and the AC? Are there some obvious (and hopefully cheap) things to check/service/replace to try and get working AC back? We sometimes have to transport our large dog and it can be unbearable on him when the AC craps out in hot weather.
***If this is going to get yanked because it isn't a TDI issue could someone tell me of a good, active form for Jetta issues?
