Hi there, I'm wondering if anyone can help me at all! I'm looking to put some aftermarket xenons in my a4 b8 but I'm not going to pay the stupid price of £500/600 from audi so just wondering if anyone has fitted any to their car and could steer me in the right direction? Also some led DRLs would be nice too :) thanks!

Hi there, you can fit them after market and there are some out there on ebay BUT...
Remember that in order to be MOT legal they should also have Headlight washers and self levelling system.

Currently the MOT states that if those systems are fitted they must work but it doesn't actually say that they MUST be fitted although many MOT centres would fail if they were not fitted.

This is what the MOT guidelines for MOT inspectors currently states:-

"Vehicles equipped with High Intensity Discharge (HID) or LED dipped beam headlamps may be fitted with headlamp washers and a suspension or headlamp self levelling system. 
Where such systems are fitted, they must work; however, it is accepted that it may not be possible to readily determine the functioning of self levelling systems. In such cases, the benefit of the doubt must be given"
What is interesting to note is that the N.Ireland MOT states :-
Vehicles equipped with High Intensity Discharge (HID) or LED dipped beam headlamps must be fitted with headlamp washers and a suspension or headlamp self levelling system

so in N.Ireland it would definitely fail.

Some good reading on the subject is here.

Thanks so much! Yea I'll definitely look into it and also the washers and self levelling! If I can't fit them too then I'll have to find a garage that'll let it go, thanks again!
