Hi Theo
This is from an earlier post. It is in the handbook
The "OIL SERVICE" light needs to be manually turned off.
I have done it on mine, you need to go to the fourth screen as follow
(You will need to hold the button for 2 seconds approx.)
Press the ADJ button once and it will take you from the Odometer screen to the TRIP A screen
Press the ADJ button once and it will take you from the TRIP A screen to the TRIP B screen
Press the ADJ button once and it will take you from the TRIP B screen to "mileage since last service" that's how I call it
Once you are on this screen press both buttons "MODE" + "ADJ" until the counter is reset back to zero, the "oil service" light will be switched off.
