Hi, 

I just noticed that the door locking stopped working on my passenger's side (car is LHD). 

The mechanism has power as it unlocks ok but doesn't lock. If i move it manually it works ok and it improved after spraying the lot with WD40. 

is the locking actuator on its way out? If so, is this DYI or do I need a mechanic? 

I guess I'll need to remove the door panel and have a look but possibly there's a fix? 

Thanks for reading.

Re: Passenger (right side for me) door lock mechanism lazy

I have the same on my older 460.  Worse - normally it doesn't central lock at all, and then sometimes it does.  Mine is a 3 door, and it affects the rear door also.  I assume its all electrical.  I was wondering if I have a poor ground on the circuits and in some conditions its fine, others not.  Because when the actuator actuates, it make a nice solid clunk.

I need to service the electric windows, and will look at the door locks at the same time, taking them on and off to check/reset the ground.

I have the same problem on my drivers side read door.

All the doors lock OK but just this one won't open.  Have to do it from inside. 

Now the weather is warming up I'll have a tinker.

Well, after a few hours I tried again after the WD 40 got into the system and it now seems to open and close fine. But I'll keep an eye on it.

Where we are only tourists carefully lock their cars, and then check that they are safely locked. As a consequence mechanisms can seize. When away in the smoke earlier in the year the central locking stopped on my 1988 460. The actuator rod sits vertically and allows water to trickle down into the gubbins. I squirted everything with WD40 and packed vaseline into the rubber dustcap to keep any more damp out and the problem has never reappeared. As a precaution I have a spare actuator (costing very few buttons from the interweb) sitting in the door pocket.

If it's all not working or all working, either way check the plug in the drives door, it sits about half way down the lower part of the door, it's white and has I think 6 wires going to it, if it's not connected properly you will have problems.

Are 463 acuators the same as 460? As last time I bought one was expensive from MB for what they are? £50 ish.
