The only time you need to drill is when the door is closed!

hi. i've had this problem with my 2002 passat saloon. The rear passenger side door is not opening from front or back. I've checked the wiring that goes into the door and there is no sign of corrosion or breaking. I've tried tapping underneath the door handle hard whilst pressing the open button on the drivers door. I have removed the inside panel. The window is attached to the inside panel. I can see the lock. Tried tapping it with a long screw driver but not opening. Can i not add voltage to the lock mechanism to open it? Horrible job to do. Anybody with any good ideas who have done this before please share. I don't fancy putting a hole in the door but will have to if nothing else works. Or i might try smashing the lock in from inside and hope that it opens up. Will need a replacement though was hoping that the lock might be repairable.

Can't get MOT without sorting it out.

Could be corrosion problems on the A post plug and socket bracket, water runs into this from the leaking pollen filter housing then creeps through the wiring loom
corroding joints all the way to the CCM. Pull up the carpet in the passenger footwell and check for green gundge in the plugs. If found cut and join the wires around the bracket.

Follow this, it's brilliant and WILL work. 2003 Passat Door won't unlock or open.pdf

right i got it working again. I got a screwdriver and placed it directly onto the lock and then got a hammer and hammered it moderately hard a few times whilst somebody was pressing the unlock button on the drivers door with the engine started to give it most voltage. after about a minute of doing it, managed to unlock.

After it worked i sprayed the lock with wd40. Now it opens and closes 90% of time and the deadlock seems to have been messed up on that lock which is brilliant because if it fails to unlock then you can open door from inside handle.

The window is a complete pain to remove (don't bother) otherwise i would have removed the whole lock and greased it.

Thanks for all the help.

It may still be best to replace lock unit in case the next time it locks permanently.

Oops I only managed to open previous post now,hope all works out well.

I used this procedure last week. It worked a treat. With a slightly different way. The hole you will drill will not put you inline with the screw!! I drilled a small hole roughly in line where the screw head is. I then looked inside with a torch to see how far away I was. I then drilled at an angle to get the head of the screw off. It fell off, I could then open the door. 2 minute after that

Hello guys. Lot's of great information here! Rear OS deadlocked several months ago (01 Passat) and today I managed to unlock it with engine on and thumping. I also disconnected the pillar harness to prevent it from deadlocking again but it also means that the electric window won’t work. Is there a way to disable the lock while keeping the electric windows working and not having to remove the inner skin?

I am kind of afraid to take everything apart, mess with the window, etc. A few articles suggest taping the window and fully removing the inner skin (in order to replace the lock). However, this one door-lock-assembly-module-removal-handle-removal-mk4-vw | VW TDI forum, Audi, Porsche, and Chevy Cruze diesel forum says that you don’t need to mess with the window, you can pull the inner skin just enough to remove the lock module (but it’s about the front door). Can the rear lock module be replaced without fully removing the inner skin and without messing with the window, etc.? Thanks.

Might be possible but won't be easy! The window only takes a couple of seconds to pop out really! Instead of pulling the grommet push. I used a punch and pushed it through. It basically fell out. Putting back in was even easier.
