I have retro fitted HIDs to all my motors, None have headlamp cleaning or self leveling,
All have been through MOT's with no issues at various MOT stations.

Even been pulled on the way to work by traffic cops, I wasn't pulled for the lights but they came up for discussion and they told me that if the beam pattern was deamed safe at MOT they are not bothered.

I'm about to buy another set for my Cupra R.

Get in touch with Nathan@xenons online. He is a great guy and will sort you out a great deal. I've bought my kits from him.
