Hey everyone, Hoping someone can provide the advice I need to get this sorted and hopefully save me from some costly dealer prices as dealer wants £120 just for diagnostics on this, let alone the fix. A couple of weeks ago, I went to flip full beams on and got the error "Light Assist Fault" - Continued driving with the mode off and manually in control of the lights (which honestly I prefer), but then noticed as I pulled up to park the reverse sensors did not kick in. By which I mean, no audible sound to confirm the module kicked on or that it had an error, and no parking sensor lines on the infotainment. When navigating into the car settings, any attempt to open up the "Parking and Maneouvering" section, results in "Function is currently not avail.". I tried to read the codes - I do not have VAG VCDS access, just a standard ODB bluetooth to phone. The codes potentially suggested a "ground fault" on reverse sensor. Is there a correlation that the two be typically linked as a fault? What constitutes a ground fault? Usually I feel when multiple things go at once, it's fuse related but the fuse diagrams don't really tell me which fuse the parking sensors and light assist functions go to. Any suggestions would be greatly appreciated. Vehicle is Skoda Octavia Mk3 (53) TDI CR 150, I think my engine code is CKFC - According to VAG DPF app. Many thanks, JD
