A6 Avant Rear washer probs

[Greengrocer]

Hi Guys. 1st post on this site so be gentle.

I've searched the site but can't seem to find anything specific about a cure for the rear washer leak I've got on my A6 Avant 1.9 TDi 130 2003. The washer pump is fine but when activated there's leak coming from inside the tailgate that promptly soaks the boot area and locking mechanism.
I've had the tailgate panel off and it would appear that a metal pipe that's part of the wiper arm spindle is broken / coroded.
Is this a known issue or is there a known repair or part I can get so solve the problem - without having to replace the entire wiper assembly?
In addition to above my central locking is also playing up. Sometimes it will not lock or unlock remotely so I have to use a key manually. After that it's fine for a time and then plays up again. It's noticable that this happens more regularly when the rear doors are used instead of just the drivers. Are these two issues connected? I've read others posts re front footwell flooding - which as far as I know I don't have.
Car is off to a local independent for a cam belt change next week - long overdue at 92k. Other than that reasonably pleased with 48mpg and reliability to date (bought 2nd hand in 2006).

Any advise on the above would be appreciated.

I have recently had the same sort of problem and cured it by the following:

1. Check the rear washer jet hose connection, which is situated in the front LHS footwell behind the hard plastic kick panel. When the pressure builds up, due to the metal pipe in the rear washer motor braking down and blocking the jet. this causes the connection to spring apart. The water then fills the foot well and eventually fills the control unit with water, hence the problems with central locking.

2. Remove the boot lid internal panel and see if the water is leaking from the washer motor. If so order the overhaul kit from VW Pt No8L0998711 @£22. It took me half an hour to fit including taking the panel off.

Hopefully this will help.

Many thanks Jesterjak. Exactly what I was after. Obviously a known fault / problem.
I assume the VW p/no you provided is common to a variety of VAG cars that use the same rear wash / wiper set up.

I went to my local VW garage because the Audi garage were not as helpfull.
The Vw garage looked on the common parts catalouge and checked that it would fit my Audi. Very helpfull.

Helston garages 01326 555 666 if you need to check it will fit.

Just checked with my local Audi parts place (Wayside) and the part is correct and will fit. Have ordered it up (£24.32) & it will be in stock by tomorrow AM.
Once again thanks for the help.

I'm having problems with my rear wash wipe too. Took the wiper motor apart last weekend and found the spindle was corroded and jammed. All cleaned and greased now but still havin' trouble with the washer.

What's actually in the refurb kit mentioned here? I might need one.

Also, can anyone confirm where the joints in the rear washer pipe are? I found one in the passenger footwell and one behind the rear wheelarch (both leaking!). Are there any more I need to check??

Thanks.
