Got to the bottle, no obvious sign of an issue having followed the tube (there was fluid in it, that seeped from the nossle when squeezed). So I wriggled the motor, nothing, so then I pulled it up, looks fine…but now it won’t go back on and keep the water in. Bugger.
quite often the motors get bunged up with crap from washer fluid being in the water, take the pump out and make the the filter into it is not bunged up.
What had happened is the rubber bung the the motor’s nozzle fits in to had fallen in to the bottle. Before I go in to info on retrieving it, I should say this is an A/c car and hence the washer bottle is under the headlight on the passenger side (in a UK car).
I managed to get to it by just pulling back the front of the wheel arch liner. The bottle isn’t secured with screws, it just pulls up, handy. Then it’s just a case of turning it upside down to get the bung back. All back together…but it’s still not working.
I’m pretty sure it’s the motor internals that have gone.
According to Deroure, it’s the same pump for A/C and non-A/C cars, part number is A111M6047S.
If that’s correct then there is one genuine (ex-Peter Smith clearout stock) on eBay. I believe this is the same as the Elise pump, in which case they’re available for about £12 for a pattern one.
Just as an aside, in my early days of S1 ownership (also an A/C car) the bottle fell of it’s mounting behind the headlight and failed to deliver the necessary fluid to the windscreen as a result. I simply put it all back together and in 11 years it never fell off again.
Had a similar problem with mine (washer, not prostate!).
Turned out that one of the wires had broken inside the washer pump connector, not least as the connector pin was only crimped onto the wire itself; the part that is supposed to grip the insulation had never been fastened so eventually the wire broke. When I took the connector apart, the second wire was just the same, so both needed work.
Also, the screenwash was starting to go gloopy, occasionally blocking the jets.
