I have a 2005 2.0 TDI which has had the passenger side door skin replaced(used from ebay) as someone kicked the old one. The replacement door was bare so all parts were transferred from the old door. Soon after we noticed the door is not locking and also the alarm, interior light and onboard computer are not acknowledging when the door is open.
My friend has a SnapOn scanner and pulled a 01332 fault code from car which says a passenger door communcation error.
The car went to a reputable mechanic and he said it was sure to be the latch/catch so had it replaced and as we expected it did not fix it.
The car is now with an auto electrician who has had the car for 6 days and still cant find the fault.
One other thing the car was not used for several months prior and the door was fitted with a flat battery(not sure if this makes any difference).
Any advise would be hugely appreciated.
