	Hi all, Perhaps not the most retro ever topic, but they were fitted since 1995 to the Mercedes S-Class (parktronic) The question: Mine don't work (no surprise there) Apparently one faulty one causes the lot to stop working. So how can I measure/tell which one is the duff one? There is an OBD2 connection, but that might be a long shot! Thanks in advance Onne

	No clue. But measuring resistance of each might give one wildly different reading...

	With the ignition on and reverse selected, go to the rear of the vehicle, put you ear to each sensor, if you have really good hearing you will hear a faint tick at each sensor The one or more that is not ticking will be the faulty sensor if you cant hear anything try listening through a screw driver or better one of these goo.gl/d8MnjQ If there is no sound from any of the sensors it would probably suggest a loom problem

	Tried the sound method, but my hearing is not very good. Might see if the stethoscope works. I'm fairly sure it's a faulty sensor, might just replace them all and see how that goes.
