Hey guys. Over the past few months my driver's seat dynamic auto adjustments on the side bolsters has been getting weak. It's to the point where I can barely notice it much. I mentioned it to my dealer, they said there is a code for the seat bladder, they wanted to replace that for $900.

BUT, when I turn off dynamic and MANUALLY adjust the side bolsters, they both inflate and stay inflated fine. Could it really be the bladder??

I don't get it. Any help would help.

Also, don't know if related...my lumbar ALWAYS shoots me in the back everytime I get in the car, I always have to deflate it, everytime. I've tried resetting the seat memory with the lumbar how I want it, but no luck.

your pump is going bad

Berti,

Did you replace your pump? If so, what part number was it? I am finding two for my CLS55.

berti_00

yes i replaced mine but for me it was two hoses that were bad and my tech replaced those... so i have another PUMP for sale when i ordered it and its still on the box it was shipped from

AMG_Guy

Will it fit a CLS55? Will you sell it to me?

Are you sure my pump is bad, when I can manually fill the bolsters fine? Just weak on dynamic..

Um - stupid question -

did you check on the setting for the Dynamic seat - I think there are 3 settings (soft med and hard ) or something like that - scroll through the menu settings on the dash - I doubt thats it but worth a try or check?

FinanceMike

You're seats will not inflate if the pump is bad. You will also see a blinking red light on the pulse button on the bottom of your seat.

Two Dynamic Seats settings: Level 1 and Level 2. Maybe switching settings may help...

I had my driver's seat completed rebuilt in 2010 by the dealership due to bad a pump, they also replaced the lines as well.

I have a black dynamic seat.. $450 shipped. PM me, I'm looking to get rid of it.

AMG_Guy

I guess I should have said in first post, I am on the strongest setting, NOT the weaker one.

Still very weak though

the seat or just the pump???

AMG_Guy

Does this look like what I need??

NO read what it says on the description "W211 E class central locking vacuum"

AMG_Guy

Thanks I did read it. Do our cars even have vacuum locking pumps though?

Look at the part number in the listing: 2118000148

According to here:

http://www.mbpartsworld.com/p/Merced...008003148.html

That part number is the dynamic seat pump...

Update:

I checked in my trunk over the weekend to check out my pump. It all seems to be fine, connections are tight, I didn't see the cover or anything melting. I opened up the cover and could see the pump. With the pump disconnected the seats obviously didn't work at all.

I reconnected the pump, and I'm able to manually fill all air pockets, but still the dynamic seats barely do anything when I drive.

Could this be the pump?? I just don't get why it would work manually but not dynamically.

AMG_Guy

Anyone shed some light? I'm about to buy a pump on eBay but don't want to waste money if I don't have to!

The pump breaks down very quickly when you have a leak, but it is not worth 900USD,

The passenger dyna. seat functions only when the senses that the someone is sitting on!

AMG_Guy

But if I can get a pump for a few hundred off ebay, is it worth trying? Or is it likely I have a leak somewhere?
