I have to change the PSE pump on the 00 E430. The dealer is asking for $190 just for initial diagnostics and then labor / parts extra comes later !
I already know it's the PSE pump. I have taken it apart as well. Not an issue. Just wanted to know if the new part will be a simply plug and play or would any other modules or the PSE itself require programming to work the the car.
thnx in advance.
