It will take time, but when done I do know the Q7 will ride outstanding on the road again.
What I have found about N199.
When "Short to positive" or "Short to ground" is found, DO NOT CLEAR THE DTC. This can cause the airbag to deploy. See repair manual for more information.
Check Wiring/Connectors from/to Side Airbag Igniter, Front Driver Side (N199)
Check Side Airbag Igniter, Front Driver Side (N199) faulty
Check Measuring Value Blocks (MVB)
Air bags to me is very costly(cause you can deploy the bag) by a DIY tech, I recommend for a professional.
