VAG seatbelt pretensioner lost comms with control module.
Discussion
Following a repair unrelated to seatbelts, I get a brief pop-up informing that "proactive passanger protection restricted"?
Conducting a scan I find...
2 Faults Found:
12680960 - No Communication with Control Module for Seat Belt Tensioner; Front Right
U017F 00 [00001001] - -
[New feature! Extended UDS fault detail is only supported by current gen. interfaces]
Confirmed - Tested Since Memory Clear
13650688 - Local data bus
U104B 00 [00001000] - Implausible signal
[New feature! Extended UDS fault detail is only supported by current gen. interfaces]
Intermittent - Confirmed - Tested Since Memory Clear
There have been no impact events. I am unable to reset.
Any ideas on way forward?
Car is 2015 MQB VW Golf.

What was the repair?
If it was in the area at the bottom of the B Pillar they may have done something related to the seatbelt connector.
If it was in the area of the bulkhead/tunnel area they may have done something related to the Safety ECU although if that was the case there would be a lot more warning flags

No point looking at plugs on seat belt etc. The fault is a communication failure between computer modules. I would be looking for the location of the seatbelt tensioner control module and checking it is connected. If it is then I would unplug it and check it has power, ground and data (canbus) at the connector.
