My MY06 R is 1 year old today. I have just put her onto 8400km (+/- 5000 miles) and when I started her up to come home the display showed the yellow triangle and the message time for regular service. Does anybody know, is this a time based service or does the R have an oil quality sensor. I picked the car up in April with 2500 miles, checked my service book and found out the car was delivered to Volvo SA as unit for display on the 3rd of August 2005, hence the low mileage. Anybody know how this service reminder is thrown up?
