How do I fix the center lock vacuum pump on Mercedes Benz c220 w202 1994,


I have had this problem on C180 ...fixed by removing rear door panel then taking the line for vacuum off lock then using an old hypodermic syringe sucked the air out and blew pressure back in this can sometimes reset but certainly gains access to boot.you need to access the panel in the boot usually above wheel arch on battery side...and check the vacuum servo for water ingress or blocked filter.these units need replacing if total failure.again a scrapyard or eBay is probably your best bet.

1993 mercedes benz 400 sel. I have no brake lights they went out about 3 days ago i check the fuses n bulb but they still dont work and my doors will no longer look with remote i check the batteries in the...


You may have two separate issues here. First as for the brake lights not working I'm guessing they all went out at once. If so there is stop lamp switch located on the arm of the brake pedal. If this switch stopped working then you will not have any brake lights. The panel underneath the dash has to be pulled out in order to see the switch. As for the locks not working the pnuematic pump which supplies vacuum for the central locking to work may have either quit working or shut down due to a vacuum leak in one of the vacuum elements. To check this go to the fuse panel in the trunk and look for the fuse for central locking and remove it for a few seconds and re insert. This will reset the pump and allow it to work again. Try the locks a few times to see if they are working. If they don't work right away then you may have a bad vacuum pump for the central locking. The central locking pump is located under the rear seat cushion on the passenger side. Hope this info helps you out if not let me know and I will try to do what I can to assist you.

The locking system is controlled by vacuum . It is really hard to figure out because there are so many things that need to be checked. You can look for broken vacuum hose under the hood. Or under the dash. There are vacuum controls in the doors. Theres a vacuum canister in the trunk. Good luck This may help some. Leave comment.

Central locking has stopped working on my 1996 audi A4


The 1996 A4 uses a central locking system which is vacuum operated. Each door has a vacuum servo which raises and lowers by air pressure created by the vacuum pump. The pump is located in the trunk right behind the passenger side tail light.

Either the pump is faulty or the vacuum lines leading to it are damaged.

This problem may be best left to the Audi dealer to troubleshoot as this is very model specific and not many small shops will have experienced this problem.

Central locking not working can it be the pump if so were is it if not what els can it be thanks


On all audi 80s I have seen, the central locking system is driven by a vacuum pump. If the systm does not work it can either be the pump, or a problem with the wiring, or even just a fuse.

The vacuum pump should be located underneath a round cover under the carpet in the right front of the trunk. If this gives any sound when you lock/unlock the doors, there is probably something wrong with either the pump or the vacuum lines. If the pump has no sign of life you should troubleshoot with a multimeter to find out if it is the pump or the wiring that is defect.

Yes, a c220 engine will fit, but you will also have to use the ECM and wiring harness from the c220
