1) having serviced the car, is there a way I can reset the service indicator?
I remember on a Rover 75 you could short two pins on the diagnostic port for a certain length of time depending which service you performed. This reset the service count down

2) Do 2005 RRS have bulb failure monitoring ? A little surprised that rear bulbs don't cause a dash message. Can't see it mentioned in the manual.

3) Behind the headlights are small 2 pin connectors (grey). Anyone know what these are for?

4) Behind the grill is a multi connector (orange wires?) Anyone know what this is for ?

Thank you

For resetting the service indicator, see the sticky in the technical section 2006 Java Black HST Supercharged

Arh having read it and tried you can't actually reset it yourself on the sport
