You can manually reset service light and interval. With Ignition on, but don't start engine, scroll with info buttons to Service Interval, then hold down
the top scroll button for a few seconds until the display shows 000, and let go, then press top scroll button to reset to 25,000 / months.
It works on mine. Hope this helps : )

Great, glad it worked.
While on the subject of service lights, after resetting service light, mine comes back on at around 12k, as we know the service intervals are 25k.
I've taken this up with Vauxhall, and they just say probably wasn't reset correctly. Even though there isn't a 12k option when resetting.
I wonder how many owners take their vans for a service, when technically it does't need it.
I never have and never will trust garages / dealerships.
