Anyway finished the 6 series yesterday, I spend about an hour bending the metal brackets for the lights and shuffling the bumper. I can say that for the first time in about 12 years it is aligned fecking perfectly.

Went to turn it on and got the instant warning message “left headlight high beam failure” at which point I had visions of dousing the car in petrol and chucking a match at it. Then remembered back to my research some months ago that you need to clear the error message as the car is relatively stupid and won’t realise it has a new light for a while as it just won’t send power to it till it decides to periodically recheck it. Reset it and it works perfectly.
I had ordered the lights from Europe so it became evident at night that they’re clearly set up for LHD cars. Something for the MOT chap to sort.
