I've started getting a warning for brake pads servicing coming on when i start up. Doesn't happen every time, but started a week or so ago.

I don't 'think' the pads need replacing but will check them over at the weekend if i get a moment.

However, checking the service indicator it shows 1100miles remaining. I tried resetting this but i can't get it to reset (the method works for all the other service indicators)

Is the miles remaining actually calculated from the sensor reading or should it reset?

If the pad sensor has been triggered by burning through the elements then it needs a new sensor to reset it..check your pads..and sensor

Thanks...will check when i get a bit of time off work!

You may also need to disengage the handbrake when resetting the indicator

I had exactly the same a while back, didn't always come on, loads of wear visible on the rear pads.

Sometimes it appeared if I'd parked with two wheels on the kerb.

It was a duff rear brake sensor even though it hadn't worn at all, looked fine

The pad sensor and 'computer' are not linked. The computer mileage 'guess' for pads is a pre-programmed generic estimate and uses mileage of the car and other driving data to give an idea.
The sensors are physical which make a circuit when they come into contact with the disc, so are your 'last line of defence' as it were.

Always find it best to ignore the computer and disconnect the sensors (but keep an eye on pad wear). More trouble than they are worth IMO.
