    The arm in the pic that is bent goes to the front headlight level sensor, what I would like to know is how will having a bent arm like this affect the headlight leveling ?

    The arm on the rear suspension is straight, the arm on the front suspension is meant to be bent. don't panic.

    yeah, was looking at mine yesterday when replacing a broken wheel arch liner. Yes its supposed to be bent, unless mine has somehow bent in the exact same way as yours. BTW, is the wheel arch line supposed to be a SOAB to get in out?

    Yes it is meant to be that shape. But he was worried that it was supposed to be straight and had somehow become bent, in which case the headlight leveling sensor would be misinterpreting the position and level of the car.
    However, it supposed to be straight, so its fine

    There are two sensors, one on the front nearside suspension and one on rear nearside suspension.
    There is a bracket on the chassis with the sensor screwed to it. The sensor has a plastic arm on the side which is bolted to a linkage rod with a balljoint at each end, this drops down to the lower control arm and is bolted on there.
    If you turn your steering hard left and look in the nsf wheel well you will see the front one. At the rear the best way in to it is to jack up the nsr corner, although you can crawl about and see most of it with the car on the deck.
