2002 FL 2.8 QS Intermittent Wipers & Keys
 

Afternoon All,

Going through the to do list on the A8 QS runabout.

Lovely old thing and in fact built 2002 but registered in 2003 so not many of those about.

Just fully serviced the old girl and done all the disks and pads all round so its a lot happier now. Gearbox booked in for a service also to ensure that's covered also to make everything as good as it can be.

Everything is working well apart from a couple of odd problems.

The first problem I have found is whilst the wipers work perfectly the intermittent does not, no matter what I set it to. They sweep once when I select intermittent but then nothing at all.

I suspect it may be the relay, does anyone have the number needed?

Secondly the keys work fine, unlock the car etc but the lock/ unlock is back to front. Most odd, so I went ahead and replaced the keys with two new ones as old ones were very worn and they still have the same problem. The chap who did it for me (Man in van, auto key chap) could not work it out either.

Hence I thought I would seek the wisdom of the collective to see if anyone has ever had the same problem?

As always thank you.

Well that's very peculiar. Are the buttons completely reversed so lock / set alarm and unlock / unset alarm? Or does it lock / unset?

Part number for the wash/wipe relay is 4B0955531E. That's an A6 number so should be easy enough to find. Our sponsors probably have a box full of them.

In short yes, press the lock to unlock and hence unlock locks so a complete reverse of everything.

Not the end of the world but with three Audi’s it’s remembering this one is a little special.

Did try many things with the Auto Electirian over an hour and it really was not that straight forward. Hence we could only make the new keys behave like the original keys.

I'm sure there's an option in the lock coding that reverses those functions, but you'll need VCDS to check.

Edit, it's 16:
1 Rear boot unlock & opened (only some models e.g A4)
2 Flash indicators on activation of alarm
4 Security central opening (drivers door only opens not passenger) with key
8 Anti-theft alarm switched on
16 Cabriolet functionality on (reverse pump direction)
32 Auto lock doors when car goes above 15mph
64 Comfort opening/closing of windows
128 No ultrasonic installed (cabriolet has no ultrasonics)
256 Unknown (rear boot logic with remote A4 ?)
512 Radio control close confirmed with one flash
1024 Anti theft alarm set confirmed by horn beep
2048 US window logic (Power windows do not work once door opened)
4096 Radio control open confirmed with two flashes
8192 Radio remote control opening/closing activated
16384 No Security central opening (drivers door opening only) with remote

Thank you very much, appreciated.

I shall fire up VAGCOM and have a play over the weekend!

Its always the way when you buy a D2, a brilliant as they are they will always have a small list of jobs that need to be done to make them perfect.

Intermittent Wipers now all back and working +++

Its never a good sign when you see three types of screw holding on the MDF panel in front of the relay panel :rolleyes:


Interestingly there was a grey VAG wipers *192 relay in its place, clearly was not well and now all replaced and working.

Three screws? Must be a special edition :ROFL:

Why would a cabrio need backwards central locking operation? I would never have figured it was just coding. Every day is a school day +++

It wasn't a time programmable relay was it?

I wonder if the pump has to be fitted a different way around to make room for the roof mechanism and motors.

Spent a little time on this one this afternoon looking at the central locking coding.

The A8 is set to 15210.

So if I add +16 it does indeed reverse the locking so the Lock button locks and the unlock button unlocks.

But...

This is still the wrong way round for the car, by this I mean when you unlock the Alarm goes on and when you lock the interior lights turn on.

So had a look at the S8 for reference and that's 15179 which makes sense as its got the boot opening and locking via speed set differently.

Interesting stuff, I wonder if the pipes on the pump have been put round the wrong way at some point.

That can be tomorrows job +++

15210 = 0b11101101101010

So 16 appears to be off already…. (read from right to left)

1 Rear boot unlock & opened (only some models e.g A4)
2 Flash indicators on activation of alarm
4 Security central opening (drivers door only opens not passenger) with key
8 Anti-theft alarm switched on
16 Cabriolet functionality on (reverse pump direction)
32 Auto lock doors when car goes above 15mph
64 Comfort opening/closing of windows
128 No ultrasonic installed (cabriolet has no ultrasonics)
256 Unknown (rear boot logic with remote A4 ?)
512 Radio control close confirmed with one flash
1024 Anti theft alarm set confirmed by horn beep
2048 US window logic (Power windows do not work once door opened)
4096 Radio control open confirmed with two flashes
8192 Radio remote control opening/closing activated
16384 No Security central opening (drivers door opening only) with remote

I should have said I tried -16 also.

Same behaviour, lock and unlock as expected and correct but car still turns the alarm on with unlock and turns the interior lights on with lock.

I have not had any need to play around with 8s central locking but if it is like C4 A6 pump and IIRC it only sucks vacuum in one direction and there are either 1 hose or going from the pump if everything unlocks together or 2 hoses if you have option to open just boot in which case 2nd hose is a separate for boot. Door/ fuel flap hose then splits and only 1 hose goes to each door only sucking vacuum and never blowing. Lock/unlock is selected by electrical valve in the door lock actuator unit switching which side of actuator the vacuum is being pulled on. Considering that your pump has been replaced it could be the wrong pump for the car where electrical pins for lock/unlock wires going to actuator units have swapped places.

Yes it should be a 8L0862257 looking at ETKA, I will have a look around the car tomorrow to see actually what it is and what's been done in there if anything.


Its all very odd, but I like these kinds of challenges!

I just realised I have not posted a picture of the old girl:

Still looking into this one as it intrigues me.

As in my central locking/ alarm is back to front. All works as it should but the open button locks and lock opens etc.

All operates as it should and coding is good as spent some time with that.

So as mentioned before I was going to change the Central Locking pump and see if that does anything.

Part number is 4A0862257 as MJ kindly provided but there are a couple of versions so I want to ensure I get the right suffix (Not near the car to pull the current one out at the moment).

Looking at ETKA "Q" looks like its for the later models, but also states there is a "P" suffix for GB models.

Hence I wanted to get the right one, plus was wondering if someone has replaced it before and that might of caused the problem if not the quite right variant was used?
