Hello Folks,

Driving with Cruise Control one day, it disengaged and all ABS, EPS, Braking lights turned on. I plugged in Xentry and it said the Passenger Rear Speed sensor had faulted. A test drive showed no reading from the affected sensor. Took the car to an Indy, they confirmed and replaced the sensor with a dealer part, however it persisted. After a few days it was said that the reluctor ring has gone which is a new driveshaft as the ring cannot be bought separatley. I've got the car back thinking about the ££££ to spend on a driveshaft. I scanned it and suprisingly 2 faults for open circuits exist. Xentry is now showng both rear sensors as faulty and no readings from both sensors. Can you have a look at the before and after picture and tell me that I'm not going crazy.
