Hello Today the spring memory was changed at my W140, finally it drives normally and does not jump anymore 🙂 But now I have a question about the level control because I found nothing in the manual about it. How does it work, always thought that when the engine runs and I sit eg on the trunk edge the car automatically pumps up. But it doesn’t do that, hear after a few seconds that under the car is a bit hissing but it doesn’t do anything. You have to drive o What’s this all about? Greetings Michael
