Hi everyone
new member here with a small issue on my 2004 w639 model viano
The rear doors not locking from the key and it gives me warning message with sound saying door is open which is a bit annoying.
I'm guessing its a boot lock and wanted to ask is there anyway to check the rear doors?
any help much appreciated

Any of the rear doors not engaging will prevent all from locking.

The U hasp for the tailgate is adjustable.
A simple check of the lock is to use a rod (Philips driver blade) to insert into V of the lock when the tailgate is lifted. Push it home and then see if the van will lock on the fob.

Be sure to unlock again prior to closing the tailgate.

The same can be tried on each sliding side door (at the back of each door).

iCarsoft would identify which lock isn't engaging, but you may well find that adjustment of the offending hasp does the trick.

Ill try it now mate thanks for the reply but I'm guessing if its a faulty lock the screwdriver testing wouldn't work as the sensor again I'm guessing is inside the lock. I red somewhere else they were by passing the locks on each door connecting the wires for the switch but I am useless with wiring. I opened the trim and there are 4 wires goes to the lock, all of them blue with colour stripes blue with red, blue with black, blues with white and blue with green.

The locks have 2 stages, did you push home each time?

yes I did that for boot lock for the sides I know if the pins on the door not contacting the plate on the B post the doors won't lock.
I'm trying to arrange a star diagnostic with specialist for tomorrow and see which lock is not locking.
thanks for your replies Martin
Great forum great people

The plates in the door pillars will engage and wear the same spot by the sprung pins in the door. It will erode the protective coating and there is temptation to scour them clean and cause more erosion.

I just did a write up but it was based on the previous Viano with electric side doors, I hadn't realised my Vito had only one pad each side.

So it may be that o/s and n/s pads are interchangeable and would then contact onto a new area of the pad.
Be sure to tie off the wires and plugs within the pillars as it would be a bitch to retrieve if they fell into the pillar.

This should confirm the lock mechanism to be ok, or not.
From the top with door unlocked and measuring at the pins,
between
1 & 2 - 0.7 ohm.
4 & 5 - 6.3 ohm.

locked,
1 & 2 - 0.7 ohm.
1 & 4 - 0.7 ohm.
1 & 5 - 6.4 ohm.
2 & 4 - 0.7 ohm.
2 & 5 - 6.4 ohm.
4 & 5 - 6.4 ohm.

I haven't concerned myself with the child lock here.

Btw,
it may be that iCarsoft V2 would be good enough for this diagnosis.
I'll try later and see if the readout is good enough, but I expect it will be.

Nope, I can't finding anything in the menu that relates to normal rear doors or tailgate.
There is options for electrically operated sliding doors but that woin't read my doors.

That's lacking. It may be an update would rectify but the last time I tried that it bricked the unit, iCarsoft were useless regards support and it was only my mate Dave (GLK) that got me out of trouble by sending me clean files.
