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.

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

I couldn't open any of the doors except the boot. Even running the
engine,
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.

Did an Audi Avant central locking pump. The interior was made totally of
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!

Sorry misread the symptoms. You can only unlock one door manually is what

you say, not the pump will only unlock one door.

Perhaps you could substitute the pump by using another source, just to test.
As I say I could almost operate the locks by lung pressure and you can only
generate a few pounds pressure using this means (3 or 4 pounds per square
inch I think, so be careful, but maybe you could use a cycle pump, or
similar to test the system. A cycle pump will generate far more pressure
than the lungs, almost certainly enough to damage the system, so go steady
if you use this idea.

My other comments, in the earlier post, regarding a repair may also apply.
