Just had TCB 32.50/09 or /09A performed




During extended idling, say 10 minutes or so, the car would ever so slowly rise, then suddenly drop back down to ride height. The drop took about 2 seconds so it was noticeble, but very smooth (no jerks). The rise was however bearly perceptible. It would repeat this over and over at idle. No codes. rise was about 1 to 1.5 inches.
I found some basic info online. The MB description as "LEVEL ADJUSTMENT WITHOUT OBVIOUS CAUSE"
Happily, the problem is gone, though it never had effect on driveability. Does anyone have the technical details and repair procedure of this bulletin, I am very curious.

I noticed the behaviour you describe a couple of times on my S55/SL55 2003 with ABC. Thought it was normal.




The two issues prompted me to bring it in. All was remedied under warranty.
Still wondering if anyone has details on the TSB 32.50/09 or 09A.

09A supersedes 09, so they are probably roughly the same.
