So my car is about out of warranty (75 Miles) and I noticed last week that my dynamic seat bolsters weren't firing.

Took it to the dealer today and apparently there were a bunch of DTC codes (Is there a website to decode these) anyways they replaced the pump.

Service advisor said its a redesigned pump (commenting not that there was anything wrong with old one)

What I did notice is the dynamic seats work a lot better now. The bolsters inflate quickly but slightly slower..... no longer feels like you are being jabbed in the side. Yes I checked the display and they are still set to powerful.

Anyways an FYI for anyone with issues. I like it a lot better!

 

Do you have a part number for this pump?

 

+1

 

+1 my Dynamic seat is not working now... dont know why... maybe the pump failed...

 

Alright Gents and the one lady I have seen on the forum.

I dug up the paperwork. Its funny they claim they could not duplicate it but replaced the pump anyway. Also the following DTC's were found - 9256,9180,9254,9259

The pump part number shows as
1 000-800-31-48 pump
1 000-800-03-18 bracket
1 000-800-35-15 hose line

says updated pump and lines.

Hope this helps.

 

BTW, how much did the dealer charge you for that ?

 

car is still under original warranty...... 25 miles left

 

Just did the same myself, easy diy.

Just make sure the dealer gives you the new hose connections with the new pump as the new part is not plug in play.

 

Does anyone know if the CPO Warranty covers DD Seat issues? Mine's working fine but am REALLY hoping this is the case in case anything goes wrong with it.

Now I'm wondering if my car ever got the new pump.

 

How long took you to do it ? can you show some instructions ?

Thanx

 

I don't have any pics or instructions but its quite simple. Remove the left side carpet from the trunk. You will then see a black box there.

Remove it as well as the tubes/hoses connected to it and the power supply

Replace the old one with the new one, and remove the old grey tubes from the other unit.

Replace with the new tubing system and button it back together.

 

WoW, thanx !

 

I just had my bracket and pump replaced at a local shop - covered under extended warranty and the prices charged were;

Pump - $615.00
Bracket - $50

Labor $59.92 for Drivers side front seat lumbar adjustment inop - replace vacuum assist pump and bracket.

Hope that helps.

 

Today my seats in my 2005 e55 stopped operating as well. (side bolsters and massage). Another thing that never worked since i bought the car used was the door handles. all 4 of them wont automatically open the doors when you are close to the car.

My question is does one pump operate all these devices? including the trunk as well?

Martin

 

your doors won't open on their own when you're close to the car, you still have to pull the door handle...

 

thanks for the info !!! still have warranty --- - i'll add these to the list of minor fixes *keyless 'driver' door sensor"* -- when i get around to it the dealer can go crazy.

 

activating or starting the dynamic seats, is that done by star?

 

^have you tried going into your settings in the cluster to change the settings for your dynamic seats?

 

xplosive,

thanks for the info, i wasnt clear in my post, i meant that when i pull the handle the door doesnt open....

does anyone know if the one pump in the trunk works the seats and the door handles?

thanks
martin

 

i tried both levels on the info cluster for the dynamic seats but neither will activate it. they worked for a year but not any more.....think ill have to take it into the dealer along with some other issues.

I just brought a new pump and hose kit and bracket. My question is, obviously there are 4 connectors going into the new pump but which colour goes into the ports labelled S B E P. Also what about the 2 old connectors that went into the old pump? Do these go to the hose kit and then the other end of the hose kits goes to the 4 pump connectors?

Bit confused. Please help.

 

If any of you fellas with the new part can take a picture of it, that would be great!

 

First pictures is the old pump vs the new pump. The last picture is the part number of the original pump which only has the 2 air connectors.

Regards.

 

Does any one know how the hose kit connects to the new pump and what about the existing connections with the 2 old air connections that were going to the old pump?

 

For me it was necessary to replace a fuse next to the car battery.
Installing or activatig the Pump over Star Diagnosis wasn't necessary.
