Title: Rear washer leak
Post by: pudding on April 03, 2017, 03:54:50 pm
Tried the search but couldn't find anything definitive, but I went to use the rear wash / wipe today and instead of a nice fan of water being blasted onto the rear screen, instead I got some gurgling noises and a little dribble coming out of the washer jet.

Got to work and there was water dripping out the bottom of the tailgate cover inside.  Nice. 

Before I go full gorilla on it yanking the cover off and probably breaking clips, are there any parts I need to arm myself with first?

Ta!

I have a colleague who had this on an A3 and it was the washer jet which leaked back through the centre of the motor if I correctly recall what he told me at the time. He bought a new motor.

Thanks mate.  I ordered all of the replaceable bits.  Main glass seal, washer jet, the hose, the hose end and a couple of other bits.

I think I know why your friend replaced the motor.  The washer jet pushes into a plastic tube that goes through the motor and known to leak.  And guess what?  That plastic tube is only available as part of the entire assembly, soi I may end up doing the same if these bits don't fix it.

Got the same problem, Pudding did you cure the problem and what part had failed ?

Pretty sure it was just the plastic fitting that clips onto the wiper motor, but I ended up replacing that as well because the previous owner fitted a reversing camera, and chopped the motor up to make the camera fit  :stupid:

You can buy the fitting and a length of hose from VW to sort it.

I would get a new washer jet insert as well.

Well it couldn't be straight forward it's leaking out of  the plastic at the bottom of the motor !

I am going to attempt a fix it  by using some araldite to seal the leak  as there is nothing wrong with the motor and a new motor is £130.

So the araldite cured one point of leaking, but it leaked else where.
So I needed a new motor looking through loads on eBay I found one with a vw parts sicker so it  must have been a replacement part.
Fitted up and works fine, point to note it is slightly different as the washer jet is in a fixed position and doesn't move with the wiper arm. Date on the motor 2015.

HNY  :drinking:

Our GTI rear washer is not working, took the back panel off and it sprays into the boot at full speed!

It doesn't seem to be the connection of the hose to the fixed part, but its firing out above that on a fixed piece

Have checked the exterior spray point with a pin and it seems clear

Any ideas?

Cheers

Decide to get a new rear wiper motor as at only £55 for a new one, and looking fairly easy to change, hopefully it will solve the above issue.

However, I can't get the rear wiper off, it seems to have fused, any ideas? Have been WD40'ing it regularly, but so far no movement...

You could try one of these.

If not I think it's a case of cutting it off, I never like messing too much with wiper motors that go through glass I always have visions of it smashing.

Funnily enough, that's exactly what I ended up buying.
The bigger puller did get the arm off, but the arm broke it as it was so seized...new arm ordered and now fitted.
The smaller puller was then invaluable as I had to reposition the new arm a couple of times to get it into the correct place and it goes on rock solid each time!
