2006 Touran central locking not always working

Hello,


My parents have a 2006 Highline Touran.


The problem is that sometimes the right door doesn't unlock when you use the central locking system. Simply pressing the 'unlock' button again doesn't help... you have to lock it and then unlock it again. What happens when you manually lock something, and what happens when it locks automatically?

As long as you only close 'on' and 'to', there will be no errors in the memory. If the device enters 'Safe' mode (meaning it locks itself because it was unlocked, but no door is opened), the following error message appears:

-------------------------------------------------------------------------------
Address 52: Door electric, passenger side. Label file: DRV\1K0-959-702-MIN2.lbl
Part number: 1T0 959 702 B
Part: Door seal 024 2301
Encoding: 0000245
Operating number: WSC 01324 785 00200
VCID: 37527BE63FDD

2 error codes found:
00097 - Motor for central locking (safe); passenger door (V162).
012 - Electrical fault in the circuit - Intermittent.
00929 - Door lock module for central locking, passenger side (F221)
008 - Implausible signal - Sporadic.


The wiring in the door and leading to the door is okay (all properly connected). In 50% of cases, it works to unlock the door (of course, with the mechanism removed, it works 100% of the time). The cables also look good, so nothing is pinched or otherwise damaged.

The question is, what should I do now? Should I replace the lock? Rewiring needed? Or is the motor in the detached house new (does that have anything to do with it?)

I would guess it's the lock, because the problem only occurs with the "safe."
Possibly a safety lever (see below). Arrow) broken, 2nd motor (only for safety function) defective, cold solder joints or similar.
