Yesterday I brought my R into the workshop because of several defects. 1. Transmission sometimes does not switch and remains in large gear, manual high and down switch is not possible. First ignition on and off it brings it to switch again. 2. Loud knocking noises from the chassis in bad ways. 3. Parking brake does not pull. So for the first time I was quite disappointed by Mercedes and all the defects already at 40,000km. I had 2 Nissan before, which had after 3 or 5 years k Today I got a call from the workshop and the master gave me the following information: to 1. a hydraulic controller on the gearbox is defective and is replaced. to 2. Airmatic valves are not working properly, the fault is the control part, which is exchanged, problem is well known with Mercedes to 3. Brake was replaced In addition, probably also something on the steering gear was defective and we repaired. My car is from 12/06, but in this case my Mercedes Ge needcar guarantee together with culant. Costs for me: none!!! I’m already excited when I get the car back on Monday.
