Faulty door lock or door module ??

[andyha2000]

When I open the passenger door on my 2009 A6 there are no puddle lights, no red light on the inner door edge and the display on the dash doesn’t recognise that the door is open
It will also lock sometimes and not others
I though it might be the door lock unit but was wondering if it may possibly be the door control module ?
Does anyone know what symptoms a faulty door module might have

Would be grateful for any advice - thanks

Can you please post an autoscan. Thanks

 

[andyha2000]

Did an auto scan tonight but it showed no error on the passenger door !! - I have a previous scan from a few months ago which showed a problem
is it worth uploading that ?

 

[myounus]

Not really. A fresh autoscan is helpful

Not really. A fresh autoscan is helpful

By autoscan we can see what exactly modules You have in car and suggest what MVB's to monitor. Faulty door contact switch normally does not result with a stored fault code.

Ok thank you - will do a new scan tomorrow

You could also login a module CCM whatever you have and see door open/closed signal for the door in question.
Very common for door latch to do this. Actually very common for cracked solder joints or micro switches to fail.
Also drop the window lock the car and from inside open door. Alarm go off?

Good Luck

This indicates faulty door lock. Of course, check wires from door lock to door controller for continuity and connectors at booth ends for corrosion before buying new door lock. Don't buy cheap aftermarket chinese or polish made locks - they work for couple weeks in best case. Then better is used original from possibly low mileage car.
