Hi all, We have this BMW here with ABS fault light on & trouble codes for LH rear wheel speed sensor. The codes are: C1E32 WSS rear left, no stoppage pulses. C1E30 WSS rear left, open/short circuit. Trouble codes obtained with KTS. When cleared, C1E32 comes back immediately & C1E30 comes back when driving.
We have changed the wheel speed sensor, but to no avail. (No wiring diag. or pin data available & sensor was relatively cheap. Thought it was worth a try)
There is 0 KPH recorded on LHR when looking in live data when driving, all other wheels are OK.
I remember having a spate of BMWs a few years ago with similar rear WSS faults which turned out to be ECU problems. Does any one know if this is the case with these nowadays?
Also I read some where that the later type of sensor could be damaged by scope testing, is this the case?
