PSE problem on an 04' SL350 R230

[knockerblip]

Help please guys. I have the well talked about water in the PSE pump problem.
Symptoms are that the convenience battery drains overnight from a short within the pump. I have tracked it down to this by observing that the battery does not drain if I disconnect the pump.
Do any of you know of anyone that repairs the PSE pumps rather than me have to buy another at silly money.

Cheers

You could try opening it up, drying it out fully, giving it a good scrub with some IPA and a stiff paintbrush (cut the bristles half way).
Worked on my SLK, and it was a real mess when first opened.

Don't forget to dry out the plugs too.

Hi just read your thread on your PSE pump. Did you have any luck cleaning it. I think that I have the same thing and now I can't even open the petrol cover. Let me know, it would be greatly appreciated. Kind regards CalDave
