Hi All
Our family L405 is starting to drive me a little crazy. I had a parking assist problem and when scanning it proclaimed a defective rear inner sensor. Great so I ordered one (LR010927 aftermarket!) and fitted it today but now it proclaims the module is defective. This seems very odd. If I remove the sensor again I can see values on the live data that are not just 255mm distance, although the moment I plug the sensor in all sensors read 255mm. Interestingly when the sensor is removed I now have 2 defective front and 2 defect rear sensors. I would just like some reverse beepers!!. Any ideas on where I'm going wrong would be greatfully received.

Many thanks

Edward

PS the attached photo shows the original sensor on the bottom and replacement on the top.

I fitted a cheap parking sensor to my daughters car and it didn't work, sensor wasn't recognised. Replaced it with a much more expensive OE one and it worked. I guess it is the difference spending £8 or £80. Maybe the ECU can tell and rejects cheap?
