What struck me after 1000 kilometers: -Polters back right. -Blinker automatically goes one side not in zero position at all, other side only sometimes. -Servo oil after tipped. -Wipe all changed. -Climate cleaned. -Div. control lights changed. -From 150kmh it gets a bit louder. -Seat heating on the left always rises out. -Central locking does not shut the tailgate. And last but not least, in the passenger area of the front window cold air flows. The higher the speed , all the more intense the airflow. Of course with the associated noise level. So I hope it’s just a jamming flap…… All in all, for a car that has 437000km on the clock and is 20 years old…..
