Hello, have an Audi 100 2,3 E year of construction 89. and the Tüv is slowly due. Have the following 2 problems. 1. The gear shift lever can be pulled up about 5 cm, then a circuit is no longer possible and you have to push the lever down again, so that you can switch. What can this be? 2. The brake does not work properly. The brake lever can be pressed down – the braking effect is good. I already had the central hydraulics fixed. It was said that the main brake cylinder should be replaced in addition. (I was standing beside it all the time during the examination and I could not find out that a more detailed examination of the main brake cylinder was carried out. Could it be due to the brake fluid – unfortunately I can not understand when the last time was exchanged. What else can this be, who has experience with it. Thank you for your tips. Greeting Bernd
