Front crash sensor pinout

Airbag light has been on and I finally decided to tear into the problem. VagCom says it’s BOTH the front impact sensors.

01739 - Crash Sensor for Front Airbag; Pass. Side (G284)
014 - Defective - Intermittent - MIL ON
01738 - Crash Sensor for Front Airbag; Drivers Side (G283)
014 - Defective - Intermittent - MIL ON

It seems fishy to me that both would be out. Does anyone have a wiring diagram or maybe some troubleshooting points to help me get these fixed?

Thanks!

I do know that there have been reports on other Audi models of corrosion influencing those sensors.

Have you pulled the connectors for inspection?

Since both are reporting problems, you can’t swap them. Depending on if you can see any wiring issues, you could purchase one of them and use it to test.

Thanks for the reply.

That was my plan. I recently had to replace the Throttle Body connectors due to them acting up, so it wouldn’t be too far off course.
