Ive taken out the Front Right (Drivers) sensor, cleaned it and the area around it and the hole it drops into. 

Had the rear left (passengers) sensor, cleaned it etc..

I also took off the under panelling and checked the lengths of wiring exposed front and rear, no obvious breaks or kinks. 

I drove the car, the faults cleared themselves.... after about 15 minutes, the lights came back on.

 

 

Any reason why the FRONT RIGHT and REAR LEFT would BOTH be showing faults???

Front right and rear left are on one brake circuit, and front left and rear right are on the other brake circuit. So if a hydraulic pipe fractures you've still got some braking.power.

That makes sense, I guess.

 

i swapped the front sensors left/right and cleared the codes. Now only rear left is showing a fault code. I’m wondering if I messed up and didn’t clear old codes, so they might have been historic.
