Dynamic Seat

[Deadeye-Detailing]

Im still waiting to collect my CL63. I found a small issue. The passenger seat side bolster blows up fine, and turns down fine, but if you then go to blow it up again right away it wont do it and the dile jumps right back to zero. It did it on the drivers side for a short while but that seams fine now.

Any ideas?

Sticking valve I’d guess.

Easy fix?

Can you hear any hissing from seat, mine has a small leak on a side cushion, which switches system off.

I’ve the same on the passenger side in the 212, found a small leak but without taking the car apart there’s no way of repairing it, oh and the bladders are flippin expensive

As i say it blows up fine then releases fine but then wont blow up again and the dial just jumps to the bottom

what age?

on a USA forum it happens all the time on all the w221s with dynamic seats (which may be the same car), most swap out the control module (done it on mine), diagnostics randomly claims an issue, you say no there isn't and it appears to work for a few months, but sometimes doesn't bother...

swapped out the module and no errors and never not works on drivers now... others now claim you can just disconnect the four multiplugs remake the connection and it gets over it (I doubt it) my rear's now started the random error message

a software update 4 years back seemed to make it worse, but the module I got off ebay is a later design, running the later software as std and it just behaves.... aged in life expectancy is my thought

module designed to die

swapped 2218709186 for 2169004400

in between they did 2218702192 and 2218703593 both 221 and 216 run same module, same software. Oh, and all the other points about air leaks and fractured pipes go without saying
