Hi, I have an Audi A6 1.8T, first registered in 2003 and these days I need to use a light abrasive to reduce the yellow film that forms on the front of the headlamp lens, to get the car through the light checks portion of the MOT. I was wondering what my options might be regarding changing the headlamp units. Do I need to fit a like for like replacement, or is there a more effective lighting technology available which it would be sensible to tap into? I would love to hear from anybody who has gone through this process. Thank you.
