Touran electrical problem with wipers

Aug 07, 2007 9 Replies

My 06 2.0 tdi Touran has developed an electrical problem with the wipers.



Ths morning, the washers stopped working and the rear wiper started working intermittantly even when it was switched off. Suspecting some computerised electrical gremlins, I got the main dealer to have a look at it.



After half an hour they said it was just a blown fuse and I was kicking myself for not having checked it myself. When I drove off, everything was working normally again. After about 5 miles, I heard a pop from the fuse box and the rear wiper stated wiping again and the washers had stopped working again. I checked the fuse (a 15 amp one) and it had blown again.



The car's going back to the dealer on Thursday but in the meantime, has anyone got any suggestions on what might be causing the problem because I suspect it's going to be a b*gger to track down.

Not your problem - it's under warranty. Chuck the car at them, collect courtesy car and let them sort it out.

Well yes but I would like my car back sooner rather than later. As an Alfa owner I would have thought you'd know the answer to almost every conceivable electrical problem. ;-)

That's the odd thing - I can't remember the last electrical problem I had with an Alfa. (No, I lie, I had to replace the wiper motor on the

156 - but that was a mechanical rather than electrical failure - I actually stripped, cleaned, re-greased and re-assembled the old one as a spare)

Then you must be an owner of a modern Alfa, not a classic one. My last Alfas all had problems with the electrics, and most of them mechanical gremlins too. Alfa have changed their cars loads since then....

I have heard of this issue before, where the wipers seem to have a mind of their own! Unfortunately, I can't remember what the cure was (though I have a sneaking suspicion that it might be either the convenience module, or the wiper stalk).

Regarding the fuse - that will have blown, simply due to the wiper motor being "overloaded" by having to work constantly on a dry screen. So, your stealer seemed to display the common trait of "muppetery", by not actually checking the cause of the blown fuse!

Because it is a fairly common problem, your local stealer should not have any difficulties in rectifying the issue.

You might want to try one of the many VAG forums out there, such as the one below \/ \/ \/ ;-)

HTH, rgds

Um, not in my case. The fuse blowing was the *first* symptom, the rear wiper didn't start running automatically until *after* the fuse blew. It's the washer fuse that blows (I presume) as the front and rear wipers still have power.

Given that there's a 15 amp fuse where the manual says there ought to be a 5 amp one I rather suspect that they just tried the "fling in a bigger fuse and hope for the best" approach.

I'll give it a try. Cheers.

Well, the 'new' one is a 1999 model, the 'old' one is a 1990 model. Don't know if you'd call 1990 'old', though.

I've had more problems with the Passat - namely the incredibly easy to trigger airbag warning light. Just vacuuming the car is enough to set it off.

Then your dealer is incompetent. Doing that sort of thing can lead to car fires. I would suggest finding another dealer or at least making this one aware of your serious concerns

Well, as has been pointed out elsewhere, the handbook is often wrong/misleading and my car should have a sticker by the fusebox to show the correct fuses. As the sticker is missing and the handbook is a bit sketchy, I'm prepared to give them the benefit of the doubt.
