This seems like the thread of confusion! My service book shows the car to be on variable servicing, which appears to be the default. The car service indicator shows 240 days till service required. Does not display letters A,B,C etc as the handbook suggests. However 240 days is approx 8 months at which point the car will be 12 months old, so looks like fixed servicing?
I have emailed the supplying dealer asking confirmation that the car is on fixed servicing. Still awaiting a reply.
