Hello everyone,

I'm new to the forum and a brand new discovery 2 owner and already I am a victim of the 3 amigos. Now the 3 lights only come on when I turn full lock left and then will reset when I turn off/on the ignition.

Anyone offer any advice??

Thank you.

When the 3 amigos rear their ugly heads, the first thing you need to do is get the fault codes read using a known compatible code reader.
To "poke and hope" will only cost you more money.

it means that the air gap was disturbed and it became normal again when you refitted the sensor cos it's about microns there ... cleanig an inductive sensor would not have any effect whatsoever cos dirt doesnt reduce the ''power" of a megnetic field

As @sierrafery has said, cleaning is unlikely to have any effect other than making sure that the sensor sits properly in its correct position.
A very basic explanation of what the sensors do.
The wheel speed sensors, there are four of them, each makes an AC signal, an electrical tone or frequency which is proportional to the road speed and are sent to the SLABS ECU. The ECU compares each signal, which when the wheels are turning at the same speed they should all be the same frequency. If one wheel is turning a lot faster and sending a higher frequency than the others the ECU reads it as wheelspin and the traction control applies a braking force to that wheel. If the ECU sees a frequency much lower from one or more wheels that the others when braking then it assumes that the vehicle is skidding and activates the anti-lock system.

As I said, the only way to conclusively diagnose the trouble is with a compatible code reader.
