A4 Central locking

[Angie Bromley]

Hi all,

After having no central locking for 10 months on my 2001 Y-Reg Audi A3 I've finally got it fixed.

The central locking failed suddenly, with the key only working in the driver's door and all other doors having to be opened with the handle from the inside. The pump was making a noise as though trying to work, but after about 5 seconds gave up without opening the doors. Specialist Audi garage said it was probably a hole in one of the pipes, but we weren't sure and thought the pump was probably faulty (disconnecting the pipe from the pump, we could tell no air was coming through the pump at all).

Dealer price for new central locking pump was about £350. We tried to buy second hand one on ebay, through parts websites and breakers yards, and finally got hold of one from the local breakers. At £50 it was a bargain, with 30 days warranty to ensure it did work (the part number for anyone interested is 8DO 862 257 E, and we've been told the part number has to match exactly).

We checked to see if it would work straight away, just plugging in, but the alarm went off and key fob wouldn't work - it needed programming in. Audi dealer wanted to charge £100, but local garage specialising in VW & Audi fixed it today for £47. It needed programming so the key fob would work, but after 1/2 hour and £47 it's working perfectly.

Suggest anyone with same problem perserveres in hunt for a second hand unit and gets it fitted by a capable garage! Good luck.

hi

i also have a major problem with my A4. the model is 1.9 tdi, YOM 12/03/97. the part number on the pump in the car now is 8LO 862 257 G. For some unknown reason, this particular part seems to be as hard to find as rocking horse poop!!

I've tried ebay, findapart and 1st choice all to no avail. Every A4 i've asked people to check has different numbers to mine. It would appear when trying to locate other parts it needed for a service by a local garage caused some problems too as it appears my model is right on the change over.

Can anybody tell me if any other pump would be compatible? My current pump has 3 plugs with 8, 12 and 16 wires and 2 pipes. I noticed one of the threads on here said they had been given an 8LO 862 257 G when their current pump had a part number of 8DO 862 257 E.

This is really getting me down now. I have a toddler and a new baby in a car seat and have to open the passenger door with the key, lean over to drivers door to open from inside and then lean into back to open rear doors. Locking is just as comical, especially when I've forgotton to unlock the rear passenger door on the drivers' side and have to start again!!

Please help!!

Thanx for sympathising!!!

After speaking to several "experts" I decided to persevere and continue my search. As it turns out, the part number for mine actually inded in an "A", (good job I re-checked). After scouring ebay for what felt like weeks, I finally found a guy in Edinburgh who was breaking his 1996 1.9 tdi. I emailed the bloke, telling him my whole sob story, (he didn't seem that impressed!), he promised to check his pump and call me back. In the meantime, 3 others I'd emailed also called me back only for all 3 to tell me the wrong part number. I was getting ready to just throw the towel in and put up with my energetic opening of the car (hey, it all burns calories no?) when the guy from Edinburgh called. He left a message quoting those magic words 8LO 862 257 "A" and I swear I punched the air and grinned like a cheshire cat...probably not the best thing to do in a packed McDonalds on Saturday teatime!!

Long story short, we agreed a price of £25 plus postage, it arrived today, I plugged it all in and hurrah!!!! I have central locking!!!!

Of course that means now I've got to find some other way to burn off those couple of extra chocolates!!!

Yes the pump does contain the alarm.however suspect pump element has broken up, 20 secs is too long to run ,if you take the pipes off the pump and cover the pump outlets with your fingers and get someone to operate the locking the pump should run and cut out almost immediatly,if it keeps running the pump is U/S.The pump is made out of a graphite type material and it breaks up .also check for pipe leaks .the pipes can split especially at the tank flap or under the back seat corners at the Tpeices ---Gen pumps are very expensive!!!

Helllo an a relative newcomer to audi DIY

have and audi a4 1995 - where the central locking pump was working overtime after a repair for door damaGE about 5 years ago - didnt pay this mucgh attanion ie the unit wopuld still try and suck air even after the doors were opened or locked - didnt pay this much attantion at the time but now I wish I had gone back to the garage that did the repair ( an audi dealer !!)

Now the pump has given up largely- although does come on for a burst of activity every other month- drAWs down the air and doors do open and lock- but then gives up next time it comes to opening the car door

my questions are these - is my unit likely also to need reprogramming if I get one from the breakers yard?

if so any reommendations on where I could go in Brum to get it programed ( assuming I can find a until with the exact same serial number which apperas to be what I need to do)

Will look on ebay and breakers yards to try and get a unit - but any other suggestions welcome

many thanks for any help as rather desperate- car also has a bad water leak -which I am going to post on another board

these two issues preventing me selling the car which I desperately need to do

thanks

Hi, Bit of a long shot with cdl faults. under the drivers rear carpet there is some wiring, there are some brown wires i think, there should be a main conection {node} this can become corroded and broken. this has caught me out once. You can also check the wires from door to pump, make sure when taking the plug apart it goes back in the right way. To code the remotes back in you need 2 keys and can be done on the door and ignition.

I have a problem with the central locking / alarm A4 on 51 plate that has been getting worse for several weeks. First of all the key fob stopped opening the doors, The LED in the door would flash but no action on the CL. The key opened the doors but interior lihts flashed, starting the engine opened all of the doors. This problem only occured when the car was cold and had not been run????
Last weekend I noticed that every minute or so one of the locks would click as if opening (car already unlocked). Last night the car has decided that the alarm will go off but no siren just flashing lights with central locking going (car still starts so no immobiliser). Audi want £110+vat per hr to have a look any suggestions. I think the something has got wet hence the problem when car is cold is it possible that part of alarm / cl has got damp. Help

Hi, Check to see if the convienience ecu is under the n/s/f floor,its in a black box. Try unpluging it and pluging it back in {make sureignition is off}

Hi,
New to the site and thinks its great, I was driving along last night and went to lower my drivers power window and it didn't work.
On closer inspection i noticed that the switches were no longer illuminating as well and that the interior lights did not also work i checked the fuses and could find none blown. I then went to lock the car on the remote to find in dispair that the central locking also no longer works, what could all this be. I drive a 1998 a4 2.4 avant.
