Hey all,
I'm having an issue with my e50 530d LCI, whenever I turn left the ABS begins hard breaking and the power intermittently cuts. The ABS system thinks the car is sliding when turning at low speed.! When I turn the DTC on, the car drives perfect but the rear end is slippy which is not great on our icey UK roads.!

What i've looked at so far;

The ABS module is not showing any errors.
The ABS sensors are all there and not damaged.
The ABS sensors all show the same rolling speed in DIS57.
Wheel alignment is fine.
Have tried 2 sets of wheels on the car.


Also, today I had someone drive the whilst I monitored the DSC sensors on the laptop.

Everything seems ok I think, not sure what the "pressure_ACC_FA" and "pressure_ACC_RA" are though, they show !-27. Anyone know what these 2 values are?

 

Was wondering if this is a steering angle issue, so I looked at it in INPA.

With the wheel at left lock is reads -358
With the wheel at right lock it reads -420

Is this normal that both left and right values are different?
