Hi, i have a 53 plate 4.4 L322 Auto i have a issue with the brakes when i am driving along the brakes will apply without touching the brake pedal there is no fault code or warning lights, i have a icarsoft reader for Land Rover when i check the brake pressure on live data it varies between 0.33 and 1.69 bar it will then jump to 2133 bar i have checked all the wheel sensor rings they are all good and all sensors replaced.
I have checked the live data on the speed sensors and all are good but i have noticed that with the car standing still i am getting a reading of 1.28kph
Just wondering if anyone can help or advise on possible cause? i have the car booked in to a LR indy workshop next week as this is the soonest i could get an appointment.

I don't know the L322 but it sounds like the ABS ECU is playing up. Check all connectors for corrosion.
The other possibility is low battery voltage which causes all manner of problems on the L322.

I have fitted a new Bosch battery and getting 12.7 volts, i have also checked the ABS connector there was one connection that was a bit green but cleaned it up but still doing the same, i am leaning towards a fault in the ABS ECU but just thought i would check on here first before pulling it off and sending it away to get checked.
