118D windscreen washer pump/motor

Hi all, I have a 2004 118d and the windscreen washer has started to play up. You can hear the pump/going but only a small amount of washer comes out of the jets. The jets are clear.

That was not a silly question, that was the first thing I checked and it was still playing up after I topped the reservoir up.

I had the same problem after some recent frosty mornings. Operating the frozen windscreen washer forced the pipes off the nozzles feeding through the bonnet. It was an easy fix once everything had thawed out. Just pushed the hoses back onto the nozzles under the bonnet.

Had the same problem, water dribbles out of the front jets.

1) So took off the front wheel
2) took of the inner arch casing in order to get at the 2 water pumps
3) Swapped around the water pipes between the 2 water pumps to isolate if it was a pump problem.
4) And it was, So pulled out the front pump and there was this white slime in the filter!! (the filter is underneath the pump unit, it sits inside the water tank).
5) Removed it and used steradent to flush out and clean any that was left in the water tank.
6) left it in for about 45min then flushed it all out.
7) Problem fixed!

It wasnt easy sliding the water tank out from the wheel arch in order to get at the pump!


Hope this helps.
