What a mess under that foam. Appears the previous owner had already been in there.


What I cannot find is a new module. Mercedes says they "have no idea from the part number"


Does anyone know the Mercedes number for the part?


Delphi A 193 820 01 26

Otherwise I'm going on Fleabay.


Thanks

Well, my first encounter with a Mercedes parts Dept they said NO.


The Pump is fine. It is the relay that is corroded. Circuit board is covered in corrosion.


I will be sealing everything up in plastic and silicone. I just need the part. perhaps another stealership will be more helpful.


The one on E-bay is used. I'm going new if I can source it.
