Can anybody tell me if i can fit my own rear sensors with a simple kit or is my 250cdi (peasant spec) in need of a canbus kit?
Thanks in advance

Showing my ignorance here - but do the electromagnetic ones only detect metal in other cars as it gets closer?


Edit:- Sorry - just clicked on the advert link and educated myself. Apologies for intrusion.
The big problem with the electromagnetic ones is they rely on motion to disrupt the magnetic field. So, they're not great for things that move slowly. The other problem is they are not very granular. So you get told there is something there, and how close, but not where it is. If they were as good as the ultrasonic ones all the car manufacturers would use them. The fact that they don't speaks volumes in my opinion.

My local Mercedes dealer supplies/fits a Cobra 4-sensor aftermarket kit but most of the retrofitters use Steelmate kits. I believe the Cobra sensors are flush, like the ones from the factory whereas most have a little pimple on the bumper that they clip into.

We have Parktronic on the CDi 250 and it's fine, but when I drive the 55 I don't really miss the parking sensors. If necessary, I just get out and have a look.
