W211 Dynamic seat pump failure and main supply air line leak
I have an W221 E63 AMG built March 2008.
Vin # WDB2110772B328243. The Dynamic seat pump stopped working. Removed it from the vehicle. The motor had completely self destructed The pump that was installed in the vehicle has 4 air pipes coming out of it. Green and Blue go into a separate reservoir. The grey pipe is short with a filter on the end. Assume it is the air intake. The red pipe runs into the car and I assume is the main supply air to the front seats. 2 Questions Question 1) I purchased a second hand pump which I believe came out of a 2011 S Class. It looks identical. It works when powered up with 12 volts on a bench. I can hardly imagine the parts can be different. The systems probably all operate the same way. The part is labelled with a Bosch part # and some Mercedes part #'s as follows Bosch 0 132 006 417 Mercedes LU A000 800 56 48 ZGS 001 HW A000 800 57 48 ZGS 001 FW A000 902 47 04 Does anyone know if the second hand part is compatible and what may be required to fit this pump and get the system operational again and a guess at a cost to do so would also also be very helpful. Question 2) I applied low pressure compressed air to the red supply air line. Turns out there is a hole in the red supply tube under the rear left door step over. I guess the hole is the cause of the pump running to the point of self destruction. Does anyone know how to remove the rear left door step over trim to trace the tube and repair it. |
