PSE pump
Hello fellow E55 owners ,
ive been running into an issue with my PSE pump. I’ve gone to couple of shops and the dealer. Some say you can buy a used one and drop it in plug and play..
while others say it needs to be programmed to the vin. Or does it only need to be programmed if it’s a new pump? Since it doesn’t have the firmware activated on it?
what say you MBworld?
Thanks.

I say a used one is hit or miss on fleebay so be sure you get a return guarantee or warranty. Get the same part number as the one in your car. You'll need to program it new or used. The reason why you need star is to mate it to your car is because the chances you find a pump from an identically optioned car is rare. By that I mean the pump part number can be the same from a 430, but a 430 may not have dynamic seats in which your pump needs to inflate. (if yours still work) With out the programming, your car does not tell the pump to inflate the seats.
I think the basics will work like doors, gas and trunk till you find someone to program. If the pump is bad it will not turn on or communicate with star.

so even if I find a pump , (with dynamic seats) option I would still have to get it programmed to operate the seats?
if anything I may find another pump to harvest a rebuild effort. I think my motor is just going bad, the doors lock, seats inflate/deflate. Everything works but just really slowly :|

I don't think so. If you find a pump from a car that had dynamic seats then it should be a direct hit plug and play. Something like that for example would be the same part number and donated by the same car (E55) Most Fleebay listings don't mention from which car the donor pump was pulled from however you might get lucky.
If you are inclined you may be able to fix yours as I believe there are some videos or someone has ventured into the waters.
For me it took 3 pumps till I got a working one. I ate up some favors from my indie at the time with the first 2 pumps so I never asked to code the third. I needed Star to determine if the pumps were good and it turned out those 2 had communication errors with Star. In the long run, it didn't matter or make sense anyway since my seats would not inflate due to a bladder leak. Everything else I need to work does- Alarm locks headrests gas door- so Im good. Trunk is starting to pop slow though
but its been 3 + years....

Just an update for those that may be dealing with the same issue;
I was able to find another PSE pump off another E55 with the same options (contour seats/trunk lid/ gas cap/ all 4 doors/vacuum manifold assist)
Upon its arrival, literally plug and play. As soon as i dropped the used PSE pump in from a donor E55 it worked perfectly.
Don't waste your time buying a brand new pump and getting it programmed which could cost you 700-800$. Do your best to find a used working pump and it will be just like new

Same here - was able to find a pump off same year E55 from these guys https://www.ebay.com/usr/european_parts. It worked like a charm, highly recommended the seller.
