Hi,
I have had the side doors and tail gate disconnected from the central locking for several years but recently the front doors have stopped operating.

I have searched through all of the previous threads on here, some of which has been really helpful in identifying the problem but I just need a little more help.

When remote locking, the doors lock and unlock again. Alarm is activted but front doors are not locked.

I can lock the passenger door with the key but the drivers door doesn't work at all.

From previous threads I recognized the wiring in the door hinge was probably cracked. It was, all 5 wires so I replaced the broken section with new wire. This was pretty difficult and because of cracks all the way along, I am unsure as to how success and waterproof it was.

Anyway, it still doesn't work and I have some messy wiring in the door. Can any body tell me what the best solution may be and should I replace all the wiring in the drivers door for sucess?

All your replies are grately appreciated.


Many Thanks

There's summat between the door handle and the trim panel...a book or magazine in the door pocket.

OR: dunno how your other locks were disconnected: power to the tailgate lock goes via an elec connector under the interior trim panel at the lock. The connector is too big so M-B production cut away the interior plastic housing around it. The housing is supported by similarly shaped metal which M-B "forgot" to cut away; hence a mild short circuit. Thus all the locks could go on or off on opening or closing the tailgate...or just hitting a bump..or sneezing.
As your side doors and tailgate lock were "disconnected" perhaps that's a red herring as maybe this particular sensor wire is still left in the system.

bloody central locking still up the creek!

Hi,
I have completely replaced the wiring for the drivers through to the passengers door, so no more cracks, all good connections, but guess what, it didn't work. It still locks and then instantly unlocks again.

I can still lock the passenger door with the key but not the drivers, its locks if I turn the key and hold it there, but as soon as I let go it unlocks again.

Could anyone say whether they thinks its something to do with the lock itself, possible a spring or something? (not got much of a clue) or still the wiring. Any help would be much appreciated as its a bit sketchy leaving it unlocked all the time!

Cheers in advance!

I had a similer in my work van back in 2001, I tried locking the drivers door from the inside handle with the door open and it bent the cable leading from the handle to the lock preventing it from moving and stopping the door from locking.

Also have you checked the filler flap lock?

The filler cap is manual locking, so hasn't been affected.

Ive always had problems with the locks jamming and the inside door handle not working because the wire inside the door has popped out of place because its stiff, but I can just take the door trim off and pop it back on then its fine again.

I should mention the door doesnt lock when sat inside by pushing the handle inwards, it jumps straight unlocked again


Thanks

Just got my V280 back from local Merc specialist - MercStar in Manchester.

They have programmed the Central Locking to operate only the filler cap and all other doors are key operated, done this to keep all doors secure when getting in and out of car.

Maybe visit your local specialist and see if the central locking need to be reprogrammed.

The central locking is a minefield, best of luck.

Yeah it sounds its, I'm wondering if the CL motor has burnt out now as well because its been like this for so long and tested endlessly. Think it might be an expensive trip to the garage to see what they say! Cheers for all the replies

Hi
I have/had exactly the same problem. The central locking locks and unlocks straight away. I can't lock the passenger door - turn the key it is locked but let the key go it is unlocked.

I found that by disconnecting the passenger door lock from the central locking the CL worked again. As the lock on the passenger door is faulty it triggered the CL to unlock.

Now I just have to fix the passenger door lock. I had a locksmith look at it and he recons there is a spring missing on the lock. Problem is I can't get the lock out, seems like I need to cut some of the door panel. (Vito 113 2000).

Anybody know how to get the lock out?

Thanks

Sorry to hijack your thread, but as the problems seem almost the same I thought it would be ok.

I don't know if it is the same on your van but often the drivers door doesn't operate the central locking if it is not closed properly. I don't know how the system knows if the door is open or not but maybe that is the problem and not the wiring your were looking at

It's possible to completely strip the lock down - I had mine in bits as the cylinder pins had siezed preventing the door from locking.

Central locking that locks then immediately unlocks is usually because the locks sensor isn't detecting that the lock is fully shut, this can be the lock position itself, the sensor switch or the wiring to the control unit.
