Audi A6 2015 C7 Allroad model - Wiring diagram

Dear all, I was wondering if someone could kindly send me the wiring diagram, detailing the connections between the Airbag control module and the front right crash sensor. My friend purchased a crash damaged 2015 audi A6 Allroad (C7 model), which he had to repair the torn wiring harness which runs from the Airbag control module behind the front, drivers wheel arch to the front bumper. Everything works fine apart from the right crash sensor which is reading no connection.

He has tried a new airbag sensor, but no change to the error codes. 

We are hoping to buzz out the wiring harness to make sure the connections are correct with low resistance

Ideally the witing diagram between the airbag module to the front bumper connector

And then the wiring diagram for the front bumper 

Many thanks in advance

Best regards

Joe
