As the post suggests, Service! shows on the DIS and I'm due an 80K full on service (car currently has 77K on the clock). The car is set up for variable service interval, last service at 61K. Question is - How far can I go before things get risky? Reason - booked in at stealership tomorrow, but having costed non-stealership prices, looking to book it in at a non-stealership. Only problem, they can not fit it in until next week, by which time I will most likely have another 300 miles on the clock. What should I do? pay the extra £110 to the stealership or wait a week and risk the extra 300 miles? Rowland.
