My 2006 Scenic 1.5dci is due its first service and it is booked in on the 13th March, however yesterday on starting up the SERVICE light came on and the spanner started flashing. The spanner is now constant but the SERVICE light is still illuminated. Reading the manual it says it is advisable to visit your Renault dealer as soon as possible. Any advice appreciated. Does it mean that its service is due or something more sinister?
