I have lost faith in the sensors. After the initial 300km my rear sensor said 30,000km I went to the dealer and they reset them to 50,000km. Within 1,000km they then read 30,000km again. Now at 4,000km the sensors read 18,000km. The rears are wearing much faster than the fronts which is a first for me in any car I have owned. I guess time will tell.
