thats new?

[euro44]

while trying to alleviate boredom have been trying to clean up the grubby bits underneath the beast, and came across something not shown in the Haynes book. front offside wheel well, matchbox sized plastic sensor? with cable to underbonnet loom . attached by 2 tiny bolts with a 2 piece arm jointed in the middle. one bit attached to the matchbox tother one to lower suspension arm. seems to measure movement as suspension operates , but WHAT?

Xenons? Sounds like the front level sensor. There's a similar set up on the rear too.

Hello euro44, does your beast have Zenons? As the box sounds like it could be the self levelling feature of the Zenons?

[euro44]

of course, yes zenons fitted, thanks.

Here it is with the arms inverted, usually the cause of faulty beam alignment

and the rear

I am not 100% but your description makes me think it is the head light automatic leval adjuster. Does your headlight switch only have one thumbwheel? if so this wheel will dim the dashboard lights and this will be the automatic level adjuster if you have two thumbwheels, then I have no idea. hope this helps solve the problem.
