      Front Impact Sensor - new or used?

      Hi

      I have a SRS message on the dash.

      DTCs retrieved
      -SRS- 0211 up front sensor front right communication fault
      -SRS- 0219 up front sensor front left communication fault

      I have cleaned the connections to both these sensors but the message persists.



      I see on ebay a lot of these sensors sold as used, way cheaper than a new one. I am tempted after comparing with the price of new sensors. Is it fine to buy a used front impact sensor?

      Do you have the Volvo software? I'm pretty sure once the Srs code is triggered it can only be cleared by their software.

      Thought of that but not sure where both the left and right harness joins together. I have a wiring diagram, I'll post it up later if anyone can help guide me where to look.

      I do have VIDA. I've erased it a couple of times already but it keeps coming back.

      This is the wiring diagram. 7/178 and 7/179 are the front impact sensor. The grey box on the right - SRS module. Looks like they connect to the module via 2 separate wires?

      Does anyone know where this sensor is on the 2003 xc70? I have removed the front bumper cover and both headlights but still can't locate either of the two front sensors. According to my local volvo dealer the part is # 30724677 and looks like this http://tinyurl.com/y9tbsjjs
