The Mrs was very generous and bought me a set of THQ V1's with the LED bulbs all round for my Christmas. I eventually had them fitted in January and love them, all working as they should. A week and a bit ago I noticed that the full beam on the passenger side headlight was flickering on and off, even when the lights were set to '0' on my T6.1 Startline, and then that bulb stayed on. I've had an error to check passenger side full beam. If I unplug and plug back in the error clears, as soon as I flash the lights it comes back 
I've swapped the LED's around and the same issue remains in the same main beam. To make it worse, the guys at THQ sent me another light cluster (thanks so much for your help THQ) thinking it may have been the unit, I tried the new unit that had halogens and that worked fine, as soon as I put the LED bulb in to the new unit same issue.
Not wanting to blind people all day with one full beam constantly on, I've swapped the LED's on main beam to halogen again for both and it works fine.
Has anyone ever heard of this at all?? The only change I've made recently is to have a towbar fitted with electrics... could this have screwed it up?
