Looking for some tech advice regarding a problem with my passenger front door.
It has lost all internal power to that door. Powder window switch, ambient light strip, led spot light that shines on the internal door handle all dead. However, window works from the driver side, door speaker working, folding mirror is working and folding mirror puddle light is working as is blind spot light.

Common sense says this is a single cable connection that has come loose in the door or in the footwell.
VW want to charge $200 OBD scan fee before they will do anything.

Questions
Would an OBD scan zero in on the exact problem?
Anyone had a similar issue / fix
Would a VW specialist be a better/ cheaper option

Cheers! And thanks for any advice
