Brake problem? Need advice please

[TimX53d]

Hi Guys.

I drive an E60 M5 while my wife drives an '09 X5 xdrive3.0d.

Yesterday she got an error coming up on the idrive screen telling her that she needs to replace the brake pads and to take the car to a dealer to do that.

The thing though is that if you go throught the various idrive menus to the brake pads it tells you that the front have something like 20,000km to go and the rears something like 40,000km. This seems strange to me and as if there is an error present.

She uses the car to drive our 4 kids around so if it really is somethign up with the brake pads I want them swapped out without delay. Though it appears to me to be some sort of software malfunction.

What do you reckon?

Cheers.
