ABC issue 2000 cl500
When driving, if I go over a bump in the road I get a ABC warning and beep.
When I park my car, after 30 minutes to an hour, the left hand front end settles down.
When I start the car, as soon as I start moving the car rises again to ride height.
Would appreciate any advice

Replace the accumulators for the warning on bumps.
Reseal the valve block with the kit from www.DIYBenzRepair.com for the car lowering when parked

Yes - clean out your block valve, had the same issue with both front wheels dropping after a while when parked. My mechanic (an independent MB genius!) told me there was some crap in the valve. He replaced the O rings and the car is perfect now.

I was a bit over my head with that particular car so I sold it. I'm really looking for a CL55 project in which I'd do coil overs and some other cosmetic stuff. Love the look but want the power too

I love ABC. I have two, a CL500 and an SL55. I do maintenance myself. Sounds like accumulators. They should be replaced every 70,000 miles would be a good estimate. Car dropping is from valves. ABC is hydraulic, basically rubber o-rings. They simply wear out. I’ve had great success with rebuilding valve blocks with o-ring kits on ebay for around $30. ABC is amazing performance wise. I spent about $15000 in repairs before I started studying it. I’ve replaced valves, struts, and hoses myself. Replacing hydraulic fluid every 30,000 would be a good idea, too. Just wished I had learned sooner.
