Quick question. I've got issues with my parking assist system on my Passat Alltrack B7. Not sure if its the sensors (they appear to work when the system works, but the whole system intermittently drops out so maybe a loose wire??), the control module, the wiring or something else. Anyone know if the OBDeleven can give me sufficient detail to troubleshoot?

I was able to fix this. By unplugging the front sensor cables from the PDC unit I confirmed the rear sensors were working (fingernail test), and then unplugged the rear senor cables from the PDC and front sensors worked (fingernail test). I took a punt that the PDC module was faulty and bought a new one. This fixed all my issues.
