just wondering if anyone knows what triggers the service indicator, is it time lapsed or sensors on the car ? break etc ?

Mine counts down when there are 30 days left until the next service. I get the number flash up for a couple of seconds when I start the car.
Not sure if it also uses mileage, because I've never exceeded the service mileage within the 12 month service period.

Service Interval Indicator (SII)

The service interval indicator is displayed in the information display. This provides information to the driver warning of an impending service requirement.

The service interval is displayed for 3 seconds when the ignition is switched on providing the service interval threshold has been reached. The service interval is reset by the dealer using an approved Land Rover diagnostic system or a manual reset procedure and, once set, counts down the mileage and time in days to the next service.

The service interval varies depending on market and vehicle engine fitment. In some Eastern European countries, South American countries, Middle East and African countries and some Asia Pacific countries the SII is disabled.

Two levels of service warning are provided; remaining distance and periodic inspection.

Remaining Distance

The remaining distance is calculated by the instrument cluster by using the current odometer value and the last service reset odometer value. The instrument cluster uses these two values to calculate the distance remaining to the next service. The remaining distance value is used to display the oil service requirement.
The mileage is displayed to the nearest 50 Km or 25 miles depending on the market configuration of the vehicle. If the service interval passes zero without being reset, the instrument pack will continue counting down and the remaining distance display will show a negative (-) value.

The trigger point for displaying the remaining distance is 600 miles (1000 km) or 30 days or less depending on the market configuration of the vehicle and is contained within the Car Configuration File (CCF).

Driver Alert

When an ignition on signal is received by the instrument cluster, the cluster software performs a check to establish if any or both of the driver service alert thresholds have been reached. If a driver alert threshold has been enabled, the applicable service information will be displayed in the information display for 5 seconds. After the 5 second display has elapsed, the information display shows the normal odometer and trip information.

Bobby,

Maybe you can help on this. I've noticed that the service remaining distance indicator doesn't reflect the 'true' mileage I've done.

What I mean is it states today it says I'm over due by 109 miles, however, it told me over 1 month ago service due in xx miles (less than 100). Based on the fact I drive 16 miles per day round trip to work thats approx 320 miles per month.

The maths doesn't add up does the computer carry out a check or is something astray with my RRS?

Cheers
