HI ALL,

I RECENTLY PURCHASED A 2015 S65 W222 WITH NON WORKING MASSAGE/DYNAMIC SEATS. I FOUND ONLY ONE CODE FOR GROSS AIR LEAK...AND I CAN COMMAND THE AIR PUMP IN THE TRUNK TO COME ON...BUT NO PRESSURE WAS BUILDING IN THE RESERVOIR AND THE PUMP WOULD TIME OUT AND SHUT OFF. I ALSO REPAIRED A HOLE I FOUND IN THE AIR HOSE UNDER THE DRIVERS SEAT. STILL GOT THE ERROR CODE FOR LEAK.. SO I SMOKE TESTED THE PUMP AND IT WAS LEAKING. SO I ORDERED A NEW PUMP AND SHOULD BE GETTING IT SHORTLY.. MY QUESTION IS WHETHER OR NOT THIS NEW PUMP...CALLED CONTROL UNIT...NEEDS TO BE CODED TO THE CAR?? I HAVE REACHED OUT TO SEVERAL MERCEDES DEALERSHIPS AND HAVE BEEN TOLD CONTRACDICTORY THINGS!! HAS ANYONE ON THIS FORUM REPLACED A W222 MASSAGE SEAT PUMP AND HAD IT WORK WITHOUT GETTING IT CODED BY THE DEAL? OTHERS HAVE A;SO SUGGESTED THAT ONLY THE MERCEDES STAR SYSTEM CAN CODE THIS AIR PUMP AND NOT MY EXPENSIVE LAUNCH BI DIRECTIONAL SCANNER.
ANY SUGGESTIONS WOULD BE APPRECIATED.
THANKS,
RICK

Did you ever get your massage function sorted out?

Yes...after replacing the leaking air pump in the trunk with a new unit from Mercedes....the new pump had to be coded by the dealer. All is working well now...hope this helps,
