Poor quality A3

Hello! I still have the old A3, built in 2000 and now 60000 km on it. I have the feeling that with every kilometer I drive something new is broken. Especially in winter there seems to be many problems. Last year my radio spun, because the volume was not allowed to regulate itself in cold. This year the chassis starts to pollen at cold temperatures very unpleasantly and cause loud noises. Then yesterday part of my instrument lighting has the gei I had to change the air mass meter even after 50000 km for over 300 euro. Then there is still the wedge belt, which at every start uncomfortably grinds, as well as squeaky noises at every left-back, supposed to come from the brake pads and is normal.. that the left window can not be completely driven down actually bothers me not so much.. the best is however, that audio stubbornly turns and does not take any cent kulanz for all the mist! so ü Think about whether it should be an a3! I’m curious what else is coming!
