Bi-xenon Headlight error

Hi, I have a 2014 Insignia 2.0 CDTI ELITE, it has the Bi-xenon lights, I’m having the dreaded condensation problem getting inside the headlight, however recently the near side headlight has started making a grinding or clicking noise. After several seconds of it doing this - it points itself left into the hedge. In response I lose full beam controls and the error codes “Headlight levelling malfunction” and “Advanced front lighting”. Does anyone know if there is anyone trustworthy on repairing these, as I have seen a few listing on ebay with each account almost slagging the other off. A new headlight, if can find the correct one is well over £800+.
