Just to say that i managed to install this microswitch and it works perfectly in the original vw california tap.
Vw t5 door microswitch.
The drivers door wasn t too difficult for me to dismantle and reassemble.
To replace the old one you need to.
Ce for vehicle brands model.
No external testing certification.
Ps i honesty think that vw engineers sit around on fridays with a round of beers and laugh at how many ways they can design insane obstacles for you and i to scream profanities while being locked out or window stuck open in a rain storm.
In my limited experience with these door modules i have not yet come across a micro switch that is actually broken they appear to be pretty tough.
Open the tap fully remove the plastic lever pull towards the side with using a screwdriver or something similar pull the micro switch out you need a screw driver disconnect the cableunderneath.
