AUDI A4 2001 Problem i need help/advice

[sheffieldadz]

I recently bought an Audi A4 1.9 TDI (130) 2001 (51) and have come across a few problems. Thanks

1 the drivers door will not lock or unlock with the remote fob but it will lock and unlock VIA the key

2 the "AIR BAG" light is on on the dash and won't go off

3 the rear passenger door non of the lights come on (footwell, door handle, door lights red and white also the interior roof lights dont come on)

when i press the unlock button all the doors open/lock apart from the drivers door.

the passenger door doesnt have a key hole.

also when i hold the unlock/lock button the windows will go up and down and the indicators will only flash when i unlock the car but not when i lock it.

thanks for your help.

Airbag sensor under driver or passenger seats may be loose. Driver side door is wiring loom i expect. 250 quid or so to replace doing mine in the next few weeks.

Alarm fob battery for point 1?

Check no water leaks. Computer, AFAIR, is under passenger carpet and water can come through the pollen filter (blocked drains, unsealed windscreen etc.).

Happened on my MY00 A6 (windscreen wouldn't seal properly), I got to the circuit board, cleaned it up dries it all out and all was OK. Bit of a pig but certainly DIY-able, just don't damage circuit board.

My symptoms were slightly different - alarm going off, hazard light sticks on and other random stuff - and it may be unrelated to your problem but something easy to check (damp carpets etc.).

The driver's door - does the passenger door have a lock on it? What happens when you use the key in that lock (if it exists)? You don't say but do any doors lock/unlock via the remote? When you lock/unlock the driver's door, does the central locking kick in on the other doors?

eBay for some batteries for a quid or two is the first place to start, assuming the central locking works on all doors but the remote doesn't. If changing the battery doesn't fix it, it could be the key, the sensor or possibly the wiring to the door(s).

If the remote locking works on all doors apart from the driver's then it's a wiring issue somewhere between the remote sensor and the lock itself.

Someone else will have to answer. I was referring to the A6. The A4 may have it in a different place but if memory serves me right, it's in a similar place. You need to lift the passenger carpets up, there is a black plastic box containing the ECU. If under the carpet is dry then I'd not go much further as it would be clear there was no leak as it takes a long time for the under-carpet to dry out unless it's been opened up.

[sheffieldadz]

ok thanks ill try under the carpet.

I had similar problems with an older (B5) version of my Audi A4.
Seemed that water was getting into the Vaccum central locking pump in the boot.

Hazards would go off, sometimes alarm and windows would go up and down as they pleased.

Car even locked me out twice.

Newer B6 audi just starting to develop problems, remote central locking went (checked battery, not that) and the DIM screen in centre of dash has started to leak......

Are all Audis plagued by these issues?

Sheffield let me assure you the problem with the drivers door is beyond doubt the drivers door wiring. Are you able to adjust your rearview mirrors?
You may or may not be able to but your problem is most likely a broken wire in the wiring loom for the door. I know this as i stated before due to my having exactly the same problem and the wiring loom is the cause.

[sheffieldadz]

i can adjust the mirrors still and use the windows also i found another problem no lights work on the pasenger rear door the lights in the handles, on the door and when u open the door the light wont come on.

[Dracoro]

I'd recommend posting (or moving) this to the Audi section, if you're lucky TameTechnician or other Audi expert will reply.

Yep, none of them do.

If its not the bulbs then its a wiring loom problem. The wiring loom for the front door is roughly 180 quid.

[sheffieldadz]

how do i move it to the audi section?

Not necessarily but geez you are having a load of issues with it. Airbag could simply be a loose wire or believe it or not it could be related to the drivers side door wiring loom being a bit fubar have you had the wiring loom in the drivers door looked at yet?
