I own a 2011 Volvo V70, it's done 48,000 miles. It's always been serviced by a Volvo dealer and I use it for towing a 1500kg caravan about 4000 miles per year. Please advise any steps I should take, over and above the manufacturer's schedule. I am particularly thinking of servicing the auto box due to the towing. The dealer says "the car will tell us when it needs a fluid change", and that seems to be the guidance in the handbook. I intend to keep the car long term as it has everything we need.
