Strange ABC issue

My 2003 SL500 raises itself then drops every 9 minutes while parked. I cannot tell if it does this while driving but definitely if running while parked. Any ideas as to what may be causing this?

I think you have an issue with the rear SAM, pull it out and look for corrosion (green and crusty) on the circuit board

What zuhow said. I have read there are some issues with water intrusion from the back window/roof seals draining and getting water in the rear SAR causing corrosion and probably other issues down the line. Also check the ABC controller. Re-seat all connectors if you can. That is known to fix connectivity issues. Do you have any codes (for the ABC) stored in the malfunction display ?
