When I open the passenger door after unlocking the van (T5 1.9) with the key fob, it doesn't acknowledge that the van has been opened and will lock the doors after a set period - is this correct? If so, then is it just a simple case of a Vagcom/VCDS ECU tweak required?

I always fear that the van will lock with the keys inside. Every other door doesn't have this effect, just the passenger one.

Thanks in advance,

Chris

It sounds like the micro switch in the passenger door lock mechanism is faulty & not "seeing" that the door has been opened, which should cancel the auto-lock function. The van thinks someone has unlocked it then walked off so after the set delay period it locks the doors again.
You might be lucky & get away with cleaning the mico-switch & lubing it with something like WD40 or you may need to replace the micro-switch and/or lock mechanism.
I'm sure if you search this forum you'll find a supplier for a suitable micro-switch, maybe Maplins. Failing that you may have to replace the whole mechanism, but try the cleaning/lubing option first.

Cheers mate. I'll try the wd40. The interior light recognises the door is open. Very odd..
I don't know for certain, but you may well find that the "single" micro-switch body actually houses 2 or more sets of contacts. Each set of contacts is used for a different purpose, much the same as the brake pedal switch, which is actually two switches in one body. One side is for the brake lights & the other side is used for things such as the cruise control.
