Hi Tony, By the service light did you mean the maintenence light which is a little flashing spanner?
If so, the manual says switch on the ignition after 10 seconds depress the accellerator and pump the brake pedal 3 times... I tried this several times and could'nt get it to work but, found switching the ignition on whilst holding down the acc. pedal and brake pedal for a few seconds works. The Renault dealer told me they were not able to give out technical information and to refer to our handbook, or to book it in with them!!
