BOTH front seats have lost the lumbar function completely. I checked F19 fuse in the trunk and it is good. Removed the air pump that's next to the fusebox and couldn't feel any vibration while the lumbar buttons were being pressed. Procedure of pressing the start button twice was followed.
When looking for a replacement pump (A211 800 0035), the description of that pump is Central Locking pump. My doors lock and unlock perfectly, so am I possibly holding a pump different from the one for Lumbar?
That's good if it's the correct pump. I can get a pump from an '07 S-class that looks exactly the same, but with a different number on it. What's the harm in trying it? My pump says, 800 02 48 and this pump says, 800 25 48 Anybody have a cross reference?
