My a4 has been experiencing problems getting the air conditioning cold. I bought a rosstech vag com system and ran diagnostics to find fault codes.

My wife has also been complaining that the memorization is not recognizing her key to adjust the seat. I've listed the registered fault codes below. Any guidance would be greatly appreciated.

Could I have a problem with my lin-bus wiring?
