Rear Level Sensor

Post by Shawnobi »

Hi,
New owner of a DS4 from 2015. I'm getting a fault warning for the adaptive xenons. Pretty sure I've found the fault to be the rear Headlight level sensor. It's not connected to the axle anymore - see below.

Q1. Do I have to buy the whole sensor or is the moving arm part replaceable?
Q2. Does anyone know part number/ a good place to get a replacement.

Thank you!

Thank you sir!
It felt like the middle pivot had seized so I will try reconditioning it first. I can see after market sensors about, but without the arm. Looks to be a 3 wire so I'm guessing the sensor is a potentiometer rather than an RVDT. So should be easy enough to check with a meter if so.

Confirmed these are complete units, so if you find you need official parts info, contact your dealer or see below:

We can help if you need an original genuine part number, part diagram or factory build sheet and can't already find the info you need on the Forum. For this service, we do ask for a membership upgrade for official parts data as we are in turn charged for this. It will cover you for future part number requests for up to 2 years, so excellent value.

If interested, links are below, then provide your vehicle's VIN in full, which will be masked automatically when you submit your post.

Thanks for that.
Just getting my head around the forum and having a nose. Will sort the membership as I have at least one other question!

It's not compulsory, but if you think you may need official part numbers or part diagrams up to the next 2 years, it may be useful.

Well it's a hot mess under there. The sensor bolts are seized in and getting a drill on them is proving difficult. Looks like a single rivet to the top of the mount which looks troublesome as well.

Are the resistance values across the pins written down anywhere I can access? Can't get a meter on the sensor where it is.

If you want the part numbers for new sensors, don't forget to post your VIN up.

There is no data for these - they are not repaired, just replaced. Basic potentiometers, but once water gets in they're pretty much toast and not worth bothering with to be honest,as they can become intermittent and when this happens it throws up errors for reliant equipment.
