    Starting Saturday my wiper would never stop. Today the boot was indicating open and the alarm was going off intermittently. Was exactly this issue - switch was in fact frozen up with water from a leaking motor.

    latta1989 - you don't need to remove the lock. I used a small screwdriver to pop the microswitch connector off the top and just squirted it with some WD40. Seems to have done the trick for now.

    The water on my motor is leaking out from around the silver lid. Does anyone know if it's possible to repair the leak within the motor? Or is it simply a case of replacing the whole unit?

    Thanks for the great advice on this thread.

    Had exact same problems as you Gareth.

    Did drying the lock an cleaning with wd40 solve all the issues? Even wiper etc.

    Is it obvious the bit to pop off?

    Cheers

    Had this with mine last week and ended up replacing them both as i didnt want to risk thinking i had repaired it then only to find out with a wet car and ice on the inside that i hadnt,i am in the trade and it cost me 120inc vat for the new boot catch and the wiper motor,i might be wrong but i couldnt see how i could do an easy repair on it as mine was leaking where the plastic cover the pipe goes to was not sealing over the shaft,i found this out after second time of removing trim because first time i did it the pipe was off so just thought that was the cause

    latta1989: WD40 only solved the boot catch/alarm problem. It is quite obvious when you look at the lock - it's the cable coming in at the top of the lock. The motor is still leaking and I just pulled the cable out to stop the wiper.

    Picked up a new motor at the Audi dealer yesterday 98. Just need to get it fitted before I go away for Christmas, looks quite straight forward.

    It would appear this is a problem on A6 Avants too!! Mine is doing the same thing, if I bang the boot in the area of the catch the lights go off only to come on again a cpl of secs later. Alarm going off in the night is a pain in the arse. I'll strip the boot lid down and have a butchers tomorrow evening. Thanks chaps, the power of the search function is strong!

    Also have a problem like this - wiper motor leaked and now I don't get the boot light on the dash and the actual boot light doesn't go on. Checked the switch and it looks pretty knackered - do i need to buy the whole book lock mechanism and the connector? If so anyone know the part numbers?

    Ive noticed also that there is still a problem with something.

    You know when you have the boot open and you lock the car the lights only flash when you shut the boot...well mine are now just flashing straight away when i lock the car as if the boot is already shut.

    Fix for that????

    you need to buy the complete lock. not sure of part number but would imagine your local dealer stock them as they sell millions each winter.

    Just wondering how people sealed the washer pipe back on?
    I tried to use silicone but it appears to be leaking again :@!
    Best way to seal it all up?

    Take the union off the wiper - cut off the pipe connector - get some tubing that goes over the existing tubing and force it on. Fix with a tie wrap.

    Push the other end onto the wiper motor inlet and tie wrap on.

    Voila !!

    This was the only way I could make it waterproof. Once the connectors have 'spread' with ice etc. they don't fit properly.

    Make sure the washer jets are not blocked and there's somewhere for the water to get out !!!!!

    got the same problem on my a3, 2004 2.0tdi. The boot clearly locks but i dont think the sensor knows this and says the boot is still open. I cant lock the car as the alarm just keeps going off. Is there a way to lock all the doors but without the alarm being set? this would be ideal just now since its late on a saturday and no garages are open til monday.

    Thanks.

    Canny simple fix mate, did mine in 20 minutes.

    You need to take out the boot lock and dry it up, focusing on the microswitch (part that tells the car that the boots open/closed).

    Open the boot and take out the surrounding trim from the boot lid, take off the lock, only held on by 2 bolts iirc. Take it inside and blast it with the hairdryer then give it a spray of WD40.

    Job done

    cheers jb0o, i just went for another quick fix that nobody has mentioned for now. I took the fuse out for the alarm system and locked the doors, the deadlocking is still on and the central locking works the same, just now alarm. l'll give your quick fix a wee try tomorrow. Defo need it sorted properly though as the rear window is misting up which would suggest the rear washer is leaking.

    When I had the problem, and after I had not only dried the microswitch but actuall removed it from the lock and wd40'd it, it all went back and everything worked (locking wise )

    Alarm still went off and I noticed the boot light was flickering on and off as well !

    Guess what the problem was ???

    I had to put a bonnet lock on a friends A4 because the bonnet was showing as open and the indicators didnt flash when locking, i fitted a new lock to it and that seemed to cure the problem...

    This started happening to my car, first the rear wiper wouldn't work or would work intermittently, then Saturday morning my alarm started going off, i only noticed the light on my dash later in the day. After looking for a solution i came across this thread and it was very useful so thank you to all of those who had posted with help and tips. I took the plastic cover off of the boot as shown in the pictures. I noticed that around the book lock, one of the connections was covered in a green corroded looking liquid. After cleaning it off and spraying it with WD40 it hasn't happened since, as well as my rear wiper started working again. Touch wood this has solved the problem of my alarm.

    Glad you got the alarm sorted.

    You will need to replace the wiper motor with the latest version to solve the problem completely.

    Okay thanks, I'll keep that in mind for a later date. Is it an easy part to get a hold of or do i need to go to Audi directly?

    Don't buy from ebay because there are loads on there that will not fit. You don't say what year your car is but I'm guessing '04 - '07

    Various places may have them and it will cost between £90 - £110. Fitting is dead easy once you get the arm off.

    Sorry, My car is '06. Okay thanks that's great, assuming there's a thread with instructions on that i could look at for guidance?

    With everyone having these same issues.. Wouldn't it be best just to disconnect the water feed from its source if possible.. I've never needed the water for the rear

    My wiper worked fine yesterday apart from no water coming out.. Thought I would check the state of the inside of the motor and ended up like this

    Haha
