2002 Audi A3 tdi, front wiper??

[Paulm81]

The front wiper motor on the car stopped working yesterday, so i went to one of the local breakers for a 2nd hand replacement and the 1st one was different then 2nd wouldn’t work at all? So tried another motor and same nothing I’ve been to 4 breakers and 7 motors that look the same with same plug and no movement? Am I doing anything wrong? Does it need coded? 

Any help is appreciated thanks

Hello Paul,

You could be right, it may need coding. Obviously, it is well beyond the bounds of probability that 7 wiper motors are at fault. 

I would now want to confirm that the motor is getting a supply voltage ( apologies if you have already confirmed this). 

If this were mine, having spent time and money in chasing around for 7 motors without success, I would now be at the point of investing an hour’s labour with a trusted local auto electrician. 

Kind regards,

Gareth.

I’ve just found out that the wipers don’t work with the bonnet open so maybe one of the first 6 may have worked but the last one was the newest and cleanest looking out of them all and I actually fitted it properly and closed the bonnet and it only does intermittent cycle on full speed?

i own a volt meter and test light if someone could help out would be appreciated as off the road due to scottish weather

I would guess the new motor needs coding as suggested by Magnet.

everyday is a school day though, I never knew that they had introduced a cut of failsafe for wipers not working with bonnet open.

Does anyone know where and how to check if coding would work? 

Nearly 3 days car has been off the road due to the great scottish weather

Hi Paul,

So you have now discovered the wipers and washers do not work with the bonnet open! Good isn’t it?

 Someone at VAG’s good idea, probably because due to one particular model’s wipers possibly catching on the edge of an open bonnet - or something! 

Re. a tutorial of using a meter. If this was my car, I would not be connecting a meter to anything on the car, if you are asking how to use a meter. These, like most other ‘modern’ cars, are ‘electronically sensitive’ and it is not advisable to go around connecting test lamps and the like unless you are competent. 

Appreciating the car is off the road, but I would now stick with my original suggestion and buy an hour’s services of a (mobile) auto electrician - it could be a lot cheaper in the long run. 

Kind regards,

Gareth. 

p.s. Wiper stalk at fault? Could be.

Is the any audi specialist or auto spark on this forum near me by any chance?? 

Not sure what the fault is or was? Car went to a garage 1st time they started playing up and was told a wiper motor was the fault? I have tried a good few only problem is at the start the bonnet was open?

a can see me selling it as nothing but problems the now

Just wondering, is there not aa way of checking with a volt meter if the motor and wiper stalk is faulty? I remember a friend showing me a wee trick to cheeck abs sensor??

im not a mechanic but do know wee bits and bobs and no scared to get dirty 

[Paulm81]

Contacted the breakers yard and was told it was an a4 the motor was removed from?

would that make a difference as the guy there said I could take it from a octavia, leon or golf?

[Paulm81]

Just a quick update 😊👍

cars fixed thank god!! Went back to breakers yard with the motor and mine with mechanism to compare properly, found an exact same in a 02 golf fitted it complete with wipers put the bonnet down and hey presto wipers are working again!!!

like to thank everyone for all the help an advice 

[Dan3222]

That’s a result. More than likely because it was an exact copy the ecu recognised it and therefore did not need codeing for new part.

[Paulm81]

Definitely dann and thank you, btw is there a trick to fit the scuttle pannel back properly?? As it’s sitting what a thought was correct but theres a gap between it and bottom of the windscreen?

[Dan3222]

Tbh not to sure, you might have to kinda hook it under the screen before putting screws in, some of these panels have a lip that sits under the screen.

I’ve noticed the plastic trim on the bottom of the screen has a channel line if you get what i mean and on the scuttle panel theres a groove type bit that it sits in??

Just asking as mine has never sat right and when on my travels round the breakers yesterday I must have destroyed 3 scuttle panels trying to get the wiper motor out? And wondering if that what was causing my leak and soaking the carpet on passengers side?

[Paulm81]

Quick question completely off topic so I apologise just now,

headlights on a3 8L can you split the lense off with out damaging it???
