Default MOT Fail on headlight aim

Had the MOT today- she failed on Headlamp aim too high and too far to the right (nearside).
Apparently the adjusters were not doing anything.
1- can I pop out the headlight without removing bumper etc to take a look? might something have popped off etc?
2- Any other thoughts please guys?

Yes you can. They're held in with 4x 8mm bolts, deqd easy to take out. They can also be used to adjust the headlight

Adjusters are a known weak point on these cars

I always find it a bit unfair to expect us to come back to it adjusted headlights, when we don't have the kit.

I suppose they want you to pay an hours labour for it!

No they are happy to adjust during the test- the adjusters did not work. I have ordered a set of adjusters. I will whip the headlamp out and see what is what

I had a similar issue at my last MOT. On mine the adjuster wheel would turn but it had not change the beam. Have a look at this thread if your sounds similar.

http://z3mcoupe.com/forum/showthread...ight=headlight

I just sprayed it with WD40 and used some pliers to make the adjustment, just made it slightly lower, they will not fail it for being too low, only too high.

I then glued the adjustment wheel back on and it works fine now

Thanks guys for all the advice. Took the headlamp out and managed to free up the adjusters. I refitted it and took her back for a retest. I was able to adjust the left/right by reaching in and turning the metal spliced bar with my fingers.
The up/down still had the cogged wheel firmly attached- so i flicked it round with a screwdriver.
so headlight adjusted and MOT issued.
