We just got our XC90 last night, and the first thing I did was open the hood, so this is fresh in my memory. There is no dip stick. There's an app for that. (i.e. this is monitored by computer)I plan to do mine. Does anyone know if the filter is on the top of the engine or at the bottom.? Also does it have a dip stick or is it one of those situations where it's just plugged and you have to buy one from Volvo.?
