Hopefully somebody can help. My central locking on my car gave up the ghost at X-mas so I checked it into a well known garage to be repaired, they said the earliest date they could look at it was 4 weeks, reluctantly i waited and dropped the car in to be told you can pick it up before 5pm and it will be repaired.I went back at 4.30 to be told, havent looked at it yet,we wont do it today and it wont be repaired either, this is just a diagnostic check to assertain what is wrong, then we will need to order parts etc and you will need to return it to be repaired at a later date, they knew by my face i wasnt please but agreed to leave the car there to be worked on 1st thing in the morning. I returned in the morning being told its a pump for the central locking and a new one is €350 plus labour to fit, but we have saved you a few quid by cleaning your old one out and it will work fine now. so i paid for the labour of the cleaning (which wasnt cheap, at least a third the price of a new pump), and a diagnostic.
Here I am 2 weeks later and its gone again,I called the garage to tell them and they said well we warned you it would go again, to which i replied no you didnt tell me that at all. I would have rathered your expert opinion,which i assumed i paid for, told me it was on its last legs and advise me to replace it as it would break again,now i need a new one, which is fine i accept that, but i had to pay for a crappy & expensive 2 week repair, also i called Audi, and they told me a '99 model diagnostic check would NOT show up something like central locking, its only for engine details in earlier models, ripped off in my opinion.
Anyway after that long rant, i feel better, and apologies for the eassy, what i want to ask is (as i cant call the garage back after some heated words were exchanged) can anybody tell me what the name of the pump is for the central locking, can i buy it over the counter myself, I have done an advanced car maintenance course and am pretty handy with cars and if its not too advanced i would have a crack at doing it myself, but i also need somebody to tell me where the pump is actually located in the car too so i can have a look at it and make a decision on self repair.
Any advise is greatly received and appreciated.
Thanks.
 
It's prob the one in the drivers door. Most cars have pumps in both front doors. Not to bad a job to do but be careful when re-connecting the locking system. Leave the door open are "fool the car" into thinking all the doors are closed. Check it, If you rig it up wrong the door could lock closed and then you end up pulling out the d/side seat or cutting a hole in the panel to open it.

Central locking pump.
 
I'm a bit confused...in what way does a pump control a central locking system?
A pump is a pneumatic device....central locking surely is an electrico/mechanical system?
 
In most cases it is an electrico/mechanical system, but audi use a door lock which is pumped by air mostly from a pump in the boot behind the r/h rear lamp. It sends this air to the lock and sometimes the pipe burst's
other times the part of the lock breaks, You can get parts for the lock but sometimes you require a lock.

very interesting
 
I thought it was vacuum.Were they still using that system in 99? There's a resevoir which supplies the system.If a pipe splits the pump then runs continuously trying to maintain the vacuum which its not designed to do and subsequently burns out/self destructs.You must find the split pipe(usually at the drivers door hinge)and repair it before replacing the pump.If not your nice new and expensive!!! pump will suffer the same fate.I didn't think Audi were still using that system in 99:confused:
