Problems with air conditioning and heating in the 2012 VW Beetle: tips and experience on fault diagnosis and repair

Hi, I had a similar problem with my 2014 VW Beetle. I am not a mechanic but have some experience as I often do minor repairs on my car myself. In my case, I had a feeling that it was possibly an electrical problem and indeed my garage later found that the wiring harnesses and connectors were faulty. It cost me about 170 euros to replace them. However, that solved the problem and the air conditioning and heating are working perfectly again. Can you tell us a bit more about your car, such as how many kilometers it has already run and when the problem first occurred? This could help to make a more accurate diagnosis. Hope this helps you!

Thanks for the quick reply! My VW has 113200km on the clock and the problem with the heating and air conditioning occurred about a month ago. Maybe it really is the wiring harnesses and connectors. I'll take it up with the garage. My last inspection was about 5000 kilometers ago. Thanks again for the tip!

No problem, always happy to help! With 113,200km on the clock, defective wiring harnesses and connectors are not uncommon, especially if the car is also driven in areas with extreme weather conditions. External factors could stress them and cause them to wear out. It would certainly not be a mistake to report your suspicions to the garage. It's good that your last inspection was about 5000 kilometers ago, but if you notice these problems, it might be time for another check. Car electrics can be pretty complicated, so it makes sense to call in the professionals if you're not sure. But hey, who knows? Maybe your Beetle just has a minor technical misstep and it's nothing major. Please keep us posted and let us know what comes out of your workshop visit. I'll keep my fingers crossed that your problem is solved quickly and inexpensively!

Many thanks for the advice and your help! With your tip in mind, I will now take the car to a garage and see what they say. Really, many thanks for your support in this annoying situation. I'll keep you posted on what comes out of it. Hopefully it's nothing too serious. See you then, and have a nice day!

I have just been to atu and have refilled the air conditioning because it is no longer cooling and they said that it is now filled but is still without function because you cannot get into the air conditioning control unit.
