Just failed its MOT on headlight (Halogen) too high and too Right. The adjustment screws seem knackered, which I thought. I was thinking of upgrading to Single Xenon anyway, but ideally I dont want to rush it. So if I can get it through the MOT first with the standard Halogens, that would be perfect. Now... Is there a way to adjust these to get through the MOT as I only have 10days for a retest? Price for replacement screws are around £30 from TPS, which seem a cheap option, but no idea how to replace. Any ideas? Big job, bumper off jobbie and take headlight to pieces?
