A1/S1 and aftermarket high-output headlight bulbs


New Member
We've had high-output xenon bulbs (Osram Nightbreaker Unlimited/Laser) in several of our vehicles, including a Jag, Lexus and Mitsubishi. As such, I've been thinking I'll eventually have a pair put in my S1 as well. However, the owner of an independent Audi garage said some Audis have thrown codes with high-output xenon bulbs!

I've never heard of anything like this before, and seeing how the high-output xenons match the wattage of OEM bulbs, I'm not really sure why it would happen either. So; has anyone here fitted Nightbreaker Unlimited/Laser xenons on their facelift 2015-2018 A1/S1?
