EGS is an electronically controlled conventional clutch and gearbox . One more thing to go wrong , in my opinion What service intervals are you on and how long does it take you to cover that mileage ? If it's 12500 and it takes (for example ) 2 years to cover that , I'd be inclined to have an oil and filter change at 6000 miles . I'd hate to be without a spare wheel even though I haven't had a flat tyre for ages
