It is a legal requirement that new cars with factory installed Xenon headlight must have an automatic levelling system that prevents the risk of dazzling other drivers, as the lights are around 30% brighter than halogens.

I can't find much info on these beasties nor how much it would cost to repair/replace.

While my C4 was in PSR Automotive yesterday having new rear Contis and a full geometry reset (thanks Paul for a superb job- the car feels so much better!) it was noted that a sensor on the wishbone for the Xenon Headlight levelling was broken.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

While my C4 was in PSR Automotive yesterday having new rear Contis and a full geometry reset (thanks Paul for a superb job- the car feels so much better!) it was noted that a sensor on the wishbone for the Xenon Headlight levelling was broken. I can't find much info on these beasties nor how much it would cost to repair/replace. Has anyone else had a similar issue?

POST 2Original post

It is usually the mounting bracket on the wishbone or the plastic link which breaks, and they are available separately (£2.22 and £13.51 respectively). If the sensor itself has broken, these are £46.70. Pic of front sensor:

POST 3 / ORIGINAL POSTEROriginal post

Not too bad then, in the great scheme of things! Thanks once again for your speed of reply and encylopaedic knowledge

POST 4Original post

i've just installed a Xenon kit for my dipped beam, but i didn't have this level sensor. Can i ask a really stupid question and ask what does this sensor do and should i get one? Thanks Martyn

POST 5Original post

Senses changes in the suspension height and compensates the headlight beam accordingly. If your xenon kit was the Porsche one it does not come with the sensor.

POST 6 / ORIGINAL POSTEROriginal post

It is a legal requirement that new cars with factory installed Xenon headlight must have an automatic levelling system that prevents the risk of dazzling other drivers, as the lights are around 30% brighter than halogens. This still requires the initial levelling to be correct (and it often isn't) It is not a requirement for aftermarket fitting, though it probably ought to be! I'm not sure if the standard halogen models have a manual adjuster so it is imperative that the lights are aimed correctly. At least with most Porsches, the luggage compartment in the front means that the lights will tend to point down when fully loaded, which is rather safer for oncoming drivers!
