Hello
i just bought a w205 c300 coupe 2017
i have few problems if anyone knows she solution please

1. i have a check engine with code of p04f0 , it appers once i put my foot on the gas , i have changed the Purge valve but the issue is still there

2. i have another code u0412 i believe it has something to do with the transmission auxiliary pump because the auto stop/start is not activated

3. after a car wash , suddenly the mirror folding button stop functioning and the mirrors are not folding at all, but still there is power and they move in all direction

4. also after the wash , the 2 buttons that close and lock the trunk are not lighting anymore and i have to slam the trunk to shut , worth to mention that the trunk works when i press the driver door button and with the key-fob, but it shut then open by it self


please let me know if anyone face these issues and if there is anything to help with
thanks alot
