Front wipers coming on randomly

[JustCruisn]

where'd you get that part number from?
i searched and found it on ECS who say "Fits vehicles without rain sensor wipers only."
Audi B5 S4 2.7T > Search > 4B0955531E
i don't have rain sensing wipers i don't think...

Another site shows it with 603 written on the top.
Have a look under the dash and pull out the relay, you'll get a part number quick smart.

They are like $20 from the states, probably quicker than the 3 days from Singapore too.
ECS have it but at almost $60 they can go jump.
$22 here $22 New Intermittent Wiper Control Module for Models Without Rain Sensor for 98-01 Beetle, 03-11 Beetle Convertible, 99-12 Golf, 99-12 Jetta, 98-05 Passat, 98-04 Audi A4, 98-05 Audi A6, 97-03 Audi A8, 94-98 Audi Cabriolet. VW Diesel TDI

yeah thanks, that's the logical way to do it.
just got to work out where it is... somewhere behind the fuse box...
might even go to a wreckers and get one for like $5, quicker and cheaper!
my wipers have now crept up the windscreen a little, not sure why. maybe just the wind or something...

Either that or your car is possessed! I'd be looking at an exorcism if the relay doesn't fix it

[McDub]

nah it's seriously possessed!
I removed the fuse for both the fronts and rears, and yet occasionally, the wipers will go up about 20-30 degrees. It's not wind, it definetly moves up like it's being driven by the motor. Would have thought the fuse would have stopped power going to them...
only logical thing i can think of is that it is a safetly mechanism that when your fuse has blown, your wipers move halfway up the windscreen to give you the unsubtle reminder that they are not working!

still yet to get under the dash and find the part number i need

i finally looked under the dash (hate removing the trim, always break clips...)
that's the wrong one i think, i need the 377 not the 603, the part number is 4B0955531A (so an A on the end not an E)
will try source one tomorrow... the E type was about $80 from VW, the A type may be cheaper who knows. hopefully vw let me test it out before i buy it (they let me do this with a MAF before )



though not sure, maybe they would both work...

strange thing is, if you look at the part number here:

http://www.ecstuning.com/Volkswagen-Golf_IV--1.8T/Search/377_Relay/2

the type A seems to be for ones with rain sensing wipers, and the type E appears to be for ones without rain sensing wipers.
the gti doesn't have rain sensing wipers so not sure why it has the A type...

[McDub]

apparently the E type replaced the A type in 2000. (strange that my car is from 2003/4 then, suppose us aussies were left with the old junk)

i sourced a relay from a mate who part owns a wreckers, just gonna cost me a beer
Going to pick it up this avo, though i've got a bad feeling about whether it'll fix the issue.
I just went to my car now, pressed unlock and the key fob, then the god damn wipers start!
Though they move very slowly and make a terrible sound like a dying horn.
what the hell is that?
both wiper fuses are pulled.
Do i have a short somwhere?
I'm hoping it is just a short in the relay, although with the fuse taken out, it sounds like i've got a short somewhere else?
crazy

[Golf Loon]

Do you have some horrific aftermarket alarm / immobilizer??? Particularly a repellor???
I finds these are all fitted by teenagers at strathfield car radios or similar and can be spliced into anything.
If you remeve all the alarm wiring and put the loom back to standard, that will fix 90% of electrical faults in the car.

[McDub]

nope no aftermarket alarm.
i went back to the car then to repair some panels, and as soon as i pressed the key fob again, same thing happend.
i turn the car on, put the fuse back in to try get it to act normal. as i'm operating the wipers nomrally occasionally i get that sound again.
i suppose it is like a sound with the motors receiving the incorrect voltage (such as the signal current)

anyway i've removed the relay now and have left the fuse in. will see how it goes.

[McDub]

car is now going wack. Lights turning off, horning sound, flashing inside lights.. Freaking me out. Now air bag fault apparently. It seemed to react whenever i touched the crossovers which are in front of the relay board... I think the problem has nothing to do with the relay as it was unplugged
What the hell do i do???

[McDub]

PROBLEM FIXED!!!!! (i think)

All good!

I think i worked out the problem!

I looked around to what was in contact with the crossovers.
everything seemed fine until i checked the earthing point.
It was loose!

I must have not tightend it properly last time i did it up.

this is an old pic of it when i was re-doing the earth for my boost gauge (re-stripped the wire so that the nut didn't do what it did here when the last person installed it...)



So i guess your wipers are the first thing to play up when this earth goes bad, followed by your headlights and instrument cluster!

now i just need to reset the airbag fault... might have to buy a v-checker

still owe my mate a beer for the relay though haha

[balkanac]

have you tried disconnecting the battery for awhile? that should clear the codes

[McDub]

ah yeah good point, will do that, cheers.
at some stage yesterday i stuffed up my knee and i've either got some cartilage floating around behind the knee cap, or i've torn a ligament.
from one problem to another....

edit: ecu reset didn't reset the airbag warning...
