There is a crash sensor mounted on the headlight mounting bracket that needs replacing. Fault code is pointing to the passenger side one so find a used sensor and replace it. Bumper will need to come off which is no big deal. You can try to remove it first and check water in the cable connectors first. But you will need a diagnostic tooo
l such as vcds to reset the fault code regardless if you only check wiring and or replace sensor.
