Left rear Sagging ABC
Hi, I'm new to this site. My '06 sl65 ABC suspension is sagging at the left rear wheel. It usually takes about 3-4 hours to notice the sag when the car is parked off. When idling, the car remains sagged and as soon as I place the gear into drive, the car levels out and stays up while driving. I would like to request some information as to the causes of this as well as how to go about repairing the issue.(please note: this car is a right hand drive)

A bulletin from Mercedes to its dealers is attached to this post and explains your problem and how to correct it.
To filter the fluid you need proprietary Mercedes hardware and software known as "Star Diagnosis". You can purchase a system from eBay or alibaba.com for as little as $300, though $350 to $400 is typical.
The bulletin mentions replacing a valve block with a new one. That is expensive. A cheap alternative to to remove, disassemble, and clean the existing valve block. A YouTube video illustrates

I experienced the very same symptoms and the flush and RODEO alone seemed to correct the problem. So far a week after the service and no sagging. Hopefully that alone will correct your problem.
