ABC Issues! Please Help!


I have a 2001 CL600. Have owned the car for one month bought with 74500 miles. Drove it for one week after seeing the red warning "ABC WARNING, DRIVE CAREFULLY". Shortly after this the rear dropped at 25 MPH taking paint off wheel wells. Flat bead to MB dealer for diagnostics. Was told the tandum pump was leaking and that would fix the issue.

One week later picked the car up. Drove 50 miles and same issue occured, only front and rear this time. Took back to MB dealer for them to tell me a valve gave out due to proper pressure and weak valve. Had them fix that and 5 days later, pick car up and drove one day and same issues happening. Only at low speeds.

Dealer came with flat bed back to MB shop. They checked it out and says all systems fine, no leaks, only code is "car to low". They dont know what to do now.
Any suggestions? Please!!

Have it towed to a different dealer that knows what they're doing.

X2 on taking it to another shop.

with the star tool, they can run several test on the system and activate the abc struts. It will also give realtime data on the system. I would assume a faulty module would show on the star tool very easily.

Unless this is all under warranty then I would let them keep swapping everything they want under the warranty so you have a new system with they get finished. I would also demand a loaner car.

Warranty on 2001 model?
I'd say the dealer is milking the customer, or is learning how to fix the car on customer wallet. Changing the shop at this time might bring some issues, but call MBUSA and ask for assistance.
