Hi Dave

I remember I needed new sensors for my CSL a few years ago (2009) and I bought them from ECP and they were manufactured by Bosch and I cross referenced them against the original part and yes they were the same. That was for an S54 so assume similar for an S50

apparently the original parts are pretty bullet proof and should last well over 100k

I did the same as Rags on the previous car ;)

You can cross reference numbers with some research to some up with the part at a much smaller price (Bosch parts)
