Here's my latest video for the first service on the Volvo XC40 2.0 D3.
Everything is accessed underneath the car.
There are 13 T30 Torx screws to remove from the under car tray and then a final trim clip you can remove with a Bojo tool.
The Sump Plug is 17mm and requires 38Nm torque when refitting.
The Oil filter drain is a 6mm hex and the housing itself requires an 82/16 tool. The torque requirement is 25Nm.
The capacity on the one I did was 5.2 litres but do check for sure as engine specs change. This exact engine is the D4204T16.
