Having been told by the other half that the rear wash wasn't working i set about investigating the problem

Pipe join behind the rear seat trim = disconnected.

click - squirt - nothing

Pipe join under the boot lid trim = disconnected

click - squirt - nothing

where the hell is the water?

****ing out under the bonnet is the answer!

the join by the bulk head was knock off when the air box was removed and put back at the service last weekend.

click - squirt - tiny dribble :'(

however the boot really smells of washer fuild

removed the entire trim panel from the boot

squirt - tiny dribble on screen + giant spray into the boot!

It would appear that with all pipes connected the washer fluid isn't getting to the screen but the pressure is causing it to spray out through where the pipe work joins the mechanism and into the boot/boot trim

I did notice that the last time it was working the washer jet had started rotating with the wiper arm rather than just spraying straight onto the window.

Does this smack of a faulty nozzle jet thats causing excess back pressure and a damp boot?

Alternatively If i need a new entire mechanism is it the same mech across the VAG group?

i.e. could i buy one off a Polo/Golf?A3 if the breakers have no Fabias?

I would say yes, it sounds like the nozzle / jet has had it. Mine's the same, so i don't try and wash the rear window atm - just use the rear wiper when it rains.

Skoda don't do a repair kit, but do the motor complete for around £70 I think.

You can however, buy a repair kit from Volkswagen for the Polo for ~ £25. I don't have the part no. to hand, but other guys on the forum have carried out the repair so if you do a search it should yield the part no. (I had saved the thread to my 'favourites' but the link doesn't work anymore). Job looks to be straight forward.

Funny cause I've just serviced my car this weekend too. I'm sure I'll get round to doing this at some point

Sounds like part of your motor casing has cracked during a hard frost, usually its unservicable now, I had the same, and the rotating jet which is servicable.

I'm just doing without at the moment, but the shape of the fabia doesnt take kindly to road spray :(

your motor casing has cracked during a hard frost

That looks about right

Think i'll see if i can get the nozzle/jet out and see if the problem still occurs then get over to the breakers and see what VAG stuff they have

The "frosted look" caused by spray and salt has quickly worn off!

just to update this a bit - have only just got round to writing the motor part number down and googling/ebaying it! :no:

Found this thread on audi-sport.net which seems pretty useful with a good pictorial how to/why it's broke!

Looks like i've got some deconstuction to do and then either a repair kit to find or a new motor - whichever is cheaper

On the same notw anyone know if one of these which i assume are the older version will be a straight replacement?

You don't need to replace the entire part if its rusted inside, you can buy a repair kit with instructions from a vw garage for about £29 with vat

As you can see, includes the pipe thats rusted through in that other forum post. Mine was rusting to the outer pipe and rotating with the arm, this fixed it nicely

edit: Whoops i should read the posts first lol nevermind

not compatable from memory buddy, might be able to strip it and use the internals though

Well Friday night ended in a huge feeling of self satisfaction.

Ok so it's not exactly a huge repair and all the right parts were supplied, as were pretty detailed instructions but it was still good to have fixed something myself.

I purchased the repair kit from local VW dealer at just under £35; which is considerably cheaper than the £70+ they wanted for a new motor

Removed my motor, took it apart, binned all the old bits (including the rusted and split leak causing pipe), put all the new bits together coated the relevant bits in grease and put it back in the boot lid. Works perfectly with a much stronger spray than i've seen before making me think it's was leaking to a small extend for the last 18 months with the super cold winter freezing the pipe and finishing it off.

Only issue i have now is that for some reason the new nozzle/jet doesn't fit 100% under the cap at the base of the wiper arm.

Although i'm not going to push it in too hard for fear of splitting the feeder pipe and starting the whole process all over again!!
