Thats what caused her E46 to fail....has factory Xenons and the washers had been disconnected.
They also failed it on no manual adjustment of the lights...the NCT tester said to the father in law that if the original lights are re-installed then there'd be no issue.

Valdas sorted the washers....so will see what is said on the re-test on Tuesday...re: the manual adjustment.... shouldn't have failed for it in the first place.
