Hi,

I have a problem with my M Reg 94 Golf CL Driver doors staying locked.

When I turn the key, all the push buttons on the doors go up and down but I
cannot open any of the doors except the boot which is the only lock that
works.

I have climbed in and pushed and pulled the buttons, they all go up and
down together, and tried the door handles.

Any ideas where to start looking?

TIA

I know on the mk4 golfs there is a fault with broken solder on the door
lock modules.

It sounds like something in the circuit of the central locking has failed.

Not familiar with this car, but maybe start with stripping the doors
down and having a look for anything obvious.

Hopefully someone with some better help will be a long to do a better
job than me :@)

I'd consider checking the central locking pump or the pipes attached to it.

It's probably in the boot.

Yep. Mk 3. Just going to look at it. I'll let you know.

Quick shake of the pump, water coming out? Makes a noise when I turn the
key. Pipes look fine. So leak could be elsewhere.

Not sure how to get the doors open.

Dunno, think I'm going to throw some money at a mechanic on this one...

Thanks for the advice everyone.

The doors on a Mk 4 are (my son says) buggers to get in, and there's an
expensive black box which apparently commonly has solder problems inside.
I think its possible to get into those and repair them....

I recall there being some pretty good step bu step stuff on the web
though, so worth checking that out.

Not sure about the Mk 3, which is what you've got right?

and trying all the locks from the inside. Madness. Anyway the mechanic
somehow got enough of the inner panel of the door off, because he thought
there was a problem with the electrical bits in the lock. How he did that I
don't know. Turned out there was no problem, but when he disconnected the
electrics on the lock the doors now open manually. Hurrah.

He reckons the problem must be the pump. Which he will change Monday
hopefully.

Had a very quick google, I don't know if this guy will send you in the
right direction:

graphite, which predictably had shattered. Can't remember if it was 300
sheets for the pump plus 90 for reprogramming, or 400 sheets plus 90 from
Audi agent. Can't see the logic of a pump failure if one lock still opens?
You can test for leaks by disconnecting from the pump and blowing down the
lines. You can detect if you just charge the lines and then no more goes in,
if you have to keep replacing the air from your mouth it's detectable and
you have an air leak. I could almost generate sufficient pressure using my
lungs to operate the doorlocks and could actually operate the fuel flap lock
by this means.

I repaired the A4 with a pump from a scrapyard Audi 80, which could be
adapted to fit the Avant pump unit body and was more heavily constructed.
Using the old pump body meant using the old electronics also, so no need for
reprogramming, so no 90 sheets. Total cost of repair £10 into the scrapman's
greasy mitt. All the secondhand Avant pumps I found were all u/s for the
same reason mine was as well as being pricey. No "pattern" units were
available.

Details of the Audi 80 repair (if this is appropriate), is on one of the VAG
repair sites, though I can't remember which one - sorry!

From what I recall, there are about 5 microswitches in the doorlocks in a
Mk4 golf, silently festering in a moist climate. Not an ideal situation for
electrical contacts. Marvellous they work at all really.

Price of a doorlock was around 80 sheets at the time I enquired.

I ain't 'arf glad my plain vanilla Sdi diesel Mk4 is totally manumatic
locking!
