This is more a question of which part I need to replace.
Whichever switch is required for the ECU to know when the rear, driver's side door is open is broken. If the car is unlocked and I open that door the interior lights don't come on, but all the other doors are fine for this.
I also think it maybe causing the auto-locking to be a bit random but that needs more investigation.
Is there a guide and part number by any chance?
Cheers!
