have a 92 sl (my 4rth SL) and out of the blue the shocks have raised the car to the max (about 8 inches between the tire and the fender). Local mechanic bled the hydraulic module and it dropped, but when I reached high speed it raised again. Also suspension lights on dash are lit. The switch to raise/lower the body does nothing.

Called the MB service center in the city and was told they need to connect a computer to the car to diagnose. Last time I did that it cost me $1500 for a new computer to control the top that quit working. In addition they are 250 miles away and its not safe to drive the car fully extended. Any ideas of a fix?
