T6 Caravelle electric sliding and latching door dead - please help

Can you show a picture of the component side of the PCB? Possibly repairable if it's a peripheral component.
 
I must admit I'm verging towards heat failure rather than water - most car components have heavy conformal coating on and that looks the same. Unless it's the terminals there it should have been happy with water running over it just about.

Is there evidence of water on the bodywork?

A mission to find though, well done.
 
Its not unheard of for water to leak through the fixing bolts of the sliding door mid rail which is right above this controller
 
Yes water there, so going to move to different location.

Common problem with water mentioned in German forums.

This controller is right in the corner behind aircon unit, i can see why it's wet.

Going to move it to the wheel arch area, but will have to move the earth.
 
Moved the module towards the middle of the arch rather than leaving it the corner.

Hopefully no more issues.
