Brake servo restricted in Audi A4 (B9) Forum Posted June 21, 2020 Hi, everyone... I've had the same problem on our 2017 Q7... parked up for most of lock down and drove it for the first time in a while yesterday and the brake servo and start/stop error appeared... Seems to be a theme here across most models...
