Break Linings Warning Icon

[X5-D-Sport]

Hi people.

I had a warning light come up, re break linings low..
So, all 4 corners changed & the light is still on...

Does it need to be turned off ?  I have an OBD diagnostic tool, which found not alerts or faults - re this light.

I also have the little 3 button plug-in unit that re-sets the service gauge, but cannot remember how to make it work, it just flashes a lot but does nothing when the buttons are pressed... is there a sequence to make it work, as I have just changed the oil & filter & need to re-set the service warning lights to zero again..

Any help welcomed.

Did you replace the sensor (s).

Offside front and nearside right IIRC (or other diagonal). There are only 2 (one ach oposite corner). When the guilty pad wears down the aemsor on end of cable creates a circuit with the metal which turns on the warning lamp. I thought a new senor sorted it. Perhaps someone else can confirm.

+1 for new sensors.

As above.  Once 'tripped' the sensor must be replaced and if you have done both ends then change both sensors.  They are not expensive from somewhere like ECP
