Preempting my cars failure of the NCT tomorrow, I’m looking for a recommended garage to fit oem halogen headlights to my e91.

I only found out a few weeks after purchasing my car privately at the end of 2019 that the previous owner had retrofitted a pair of oem xenon headlights, however without the self levelling mechanism and washer jets, it’s pretty likely that it’ll fail the NCT I have booked for tomorrow.

The reason I’m not particularly keen to give this a go myself is because from my online investigation, it looks like some wiring is required when retrofitting xenons, and I don’t fancy tackling this myself. It also sounds like xenons need to be coded into the ecu, so will likely need the halogens coded back too.
