drgork Member Date registered: Apr 2006 Location: Chattanooga, TN Vehicle(s): 2000 G500 Posts: 42 | My central locking quit working today I got in my 2000 G500 today and locked the driver's door and noticed none of the other locks locked. I unlocked and locked the driver's door a few more times and nothing happened. I also noticed when I try to lock the car using the remote, nothing happens. Any suggestions? My first thought is the actuator on the driver's door is broken. Would that cause all the other locks not to work? This may have been addressed before (I have to admit I didn't do a search). Any thoughts are appreciated! Thanks, Danny | ||

I forget the procedure but it should be in your manual, I think you hold the lock button for a few seconds until both green and red lights under the mirror come on (if yours is a "true 2000" and not Europa-2000 which is equivalent to european 1999) I am not sure how the central locking is on non-steeringwheel-control 500's. | ||

FWIW, many of the Europa Int'l 2000 G500's, including Danny's and mine, do have the steering wheel controls. The changeover happened sometime in mid of 1999. | ||

I remember reading about how it takes a long time to "federalize" them which results in them reaching US buyers a while after import, so I wanted to make sure I was talking about the same car. edit: when I say the lights under the mirror "come on", I mean "start flashing". | ||

drgork Member Date registered: Apr 2006 Location: Chattanooga, TN Vehicle(s): 2000 G500 Posts: 42 | RE: My central locking quit working today I checked fuse 16 and unfortunately it was not blown. I checked the fuse with the fuse checker and it was fine. I will now move my attention to the door and see what's going on with the lock from that end. If it is the actuator, I won't be surprised. I had to replace my fuel door lock mechanism a few weeks ago. That device is a small motor and nylon gear arrangement. The gears had simply worn out and stripped, making a terrible noise when I unlocked the car. When I removed the old one, it fell apart in my hands. Any logic to replacing the electric window regulator, etc. while I have the driver's door apart? I thought I had read where those too go out after a while. Thanks for the help. Danny | ||

drgork Member Date registered: Apr 2006 Location: Chattanooga, TN Vehicle(s): 2000 G500 Posts: 42 | RE: My central locking quit working today Quick update. I replaced the 2 wire actuator in the front passenger door and the 5 wire actuator in the driver's door and my locks still don't work. As I mentioned before, I can push the key lock button and the green and red lights as well as the parking lights work (to acknowledge locking or unlocking the car) but the locks won't lock or unlock. Even when I'm in the car with the door shut, and I lock the drivers door lock, the other door locks do nothing. When I was inside the doors I checked for loose connections, broken wires, etc. and found nothing. Any other thoughts or ideas are greatly appreciated. I will probably take it to my independent mechanic in a few days if I can't nail it. Thanks, Danny | ||

LPG Date registered: May 2006 Location: Oslo, Norway Vehicle(s): G | RE: My central locking quit working today No this is located in the "electronic box compartment" under the hood. It's located underneath another relay; this relay is big and also has fuses on it. The one you are looking for is quite small and have big leathering saying “KIEKERT” the part number is: A 009 545 19 32. | ||

drgork Member Date registered: Apr 2006 Location: Chattanooga, TN Vehicle(s): 2000 G500 Posts: 42 | RE: My central locking quit working today Success! LPG was right. The central locking relay was at fault. I got a replacement from Vlad (part # A 009 545 19 32 - just as LPG said). On my 2000 G500, the part is in the metal box (under the hood against the firewall) where the K40 relay is located. The Central locking relay is actually under the tray that hold the K40 relay. You must remove the K40 relay first and then remove the metal tray. There are 2 nuts that hold the tray in place. Once that's out of the way, you can get to the relay. It is held in place with 2 nuts as well. Space is very limited and tight in there so it takes some effort to remove it. I had some difficulty getting a small socket in there to loosen the nuts. The wires go into the relay via a multi-pin connector with locking tabs on the sides. There isn't much slack in the wires so you really have to be careful removing the connector. You also have to be careful removing and replacing the nuts. If one fall down in the box, you may never see it again! If you have to do this, I would recommend mounting the new relay first and then pushing the connector onto the pins of the new relay. Once connected, all you have to do is replace the K40 tray, K40 and put the cover back on. All in all, I think it took about 45 minutes. Once in place, I was glad to hear the old clunk of the locks working again. Thanks for everyone's help as always! Danny | ||

I also noted that if I push the driver's lock down, a second later I hear a faint click from the passenger footwell area. Unlocking the lock I hear the same thing. I checked fuse 16 and it appears to be okay. Any additional thoughts before I order a relay? | ||

A deep 8mm socket with a 1/4 drive is perfect for the 4 small nuts. I pulled the circuit card out and and made a few notes. I think if I were to have removed the traces and resoldered the 2 joints identified the part is probably still usable. Sometime in the future I will do it and reinstall for a test. Thanks to Danny's excellent directions to the relay in the NASA style relay crib, not a time consuming or dirty job.

As theorized, resoldering all of the connector header pins and relay pins will fix the problem, at least in my experience. To prevent it from happening again, reinforce each joint with a small piece of copper braid. This is easily made by using copper solder wick or by stripping out a short section of copper shield from some RG-58 style coaxial cable. Take a length of briad several inches long an just press the end down into the solder pool at the board. Let it dry, then cut and trim off the braid leaving only what is now submerged in the solder joint. Edited by G4Garret 4/11/2009 12:49 AM | ||

I recently resoldered the K40 relay as the car was "dead", no door locks or starter. I did not know that there was another relay for the doors until now, so i followed your instructions and found my relay with the exact same pins to resolder. The whole operation took me 40 minutes without mishaps and now all is working again, fantastic! Great forum... Edited by Container 4/11/2009 11:49 AM | ||

AlanMcR Expert Date registered: Apr 2006 Location: US, CA, Los Altos Vehicle(s): G300DT E300DT 230SL Posts: 3500 | RE: My central locking quit working today Hmm. I'll have to pull the door lock relay and take a look at it. I would have assumed that this relay would have failed first in my truck. It is mounted not more then 5" from the turbo with only a piece of sheet metal and a heat shield to protect it. | ||

It is mounted not more then 5" from the turbo with only a piece of sheet metal and a heat shield to protect it. From what I understand, it is not exterior heat that is unsoldering these pins, but from the relay itself if you click-click-click the lock too fast. In my case I hade an intermittent immobilizer problem and clicked on and off with the key to get it working. Which eventually made the door locks not work as well. So for me the K40 relay fault made me cause the lock relay fault. Now both are resoldered and all is fine! | ||
