ABC Problem-'02 CL500

[Jud Chapin]

The problem I'm having with my '02 CL500 is the front end drops (evenly) after sitting for 2-3 weeks. Then, when you go to start it, a warning message appears saying "do not drive car, etc.". After starting, the front end rises and all is fine. I took it in for service (warranty) and was told by MB that the "front valve block for ABC is leaking internally" so they replaced the valve and flushed the system. They supposedly discussed the problem with MB Headquarters while working on the car. After getting the car back, I let it sit for another couple of weeks, and not supprisingly, the front dropped again.

At this point, I'm undecided about taking it in again since I'm unsure if they can fix it and hate going there anyway lest they screw up something else, among other concerns. In reallity, if I used the car more I wouldn't even know the problem existed. What bothers me though is whether or not this could get worse or lead to other ABC problems later. On the other hand, if this is the only problem (if this is really a problem) I'll have with the ABC, I couldn't care less.

I still have about 6 weeks left on factory warranty and have Starmark extended warranty for another 3 years. I'm wondering if anyone has had any experience with this and what they suggest.
