Just picked up a 66 plate Ibiza FR 1.2. The service manual has the 'fixed mileage/duration' box ticked on the first service in the booklet (not longlife). The car has been serviced every year (last one just happened) and yet the service menu tells me the next oil change service is due in 403 days?? The only thing I can think of is that the car's internal system is somehow set to longlife? Maybe due to a battery disconnect? I'm expecting the next service to be in ~365 days or 10k miles.
