New Mercedes 08 CL550 Owner (4 days) Dynamic Seat Issue
Hello forum!

New member here. Picked up an 08 CL550 Saturday. I have a seat issue. I have read a million threads but cant figure out the best plan of attack. For starters the passenger seat work perfect. I am not sure if there are two pumps or one? The drivers seat.... the massage function works perfectly. The side and shoulders work for a second to a minute then deflate. The dynamic comes in but goes off almost instantly. From what I am able to figure out myself from reading threads, the pumps is good, maybe a bladder is bad or a valve? Is this a self fix or a dealer. How much do you think this is going to set me back?

Thanks a lot in advance!!!

Most likely a puncture in one or more bladders. I've replaced right side 3 times in 12 months because of small leaks. Side would inflate then lose pressure over 10-20 minutes. Dynamic function on that side was weak or didn't work at all. Fortunately caught under warranty otherwise $1400.

Should be just a stuck valve on the valve block on the rear, they can do this.

STAR will tell what one is at fault

Hi,

I just got my CL65 ('08) three days back and have a similar problem, whatever position I select in the command menu and change the setting, it seems to inflate for a second and then the marker goes back down again to zero. Where is the pump / valve?
