To reset the service indicator on the scenic II is as follows:
Scroll through the trip computer using the button on the end of the right hand stalk control until you get to the miles till service indicator (or the “change oil soon message” will appear if due)
Then press and hold the same button in and hold it. The miles indicator will then flash then change to 18000, keep the button pressed until the 18000 stops flashing.
NOTE: If the word “service” appears on your dash then that does NOT mean that a service is due. It is an indication that the vehicle is faulty and has a stored major fault code.
The indicator that a Service is due is when the words “change oil soon” appears or the spanner starts flashing.
