As you look at the front of the car with the bonnet up, it's at the back of the engine on the left, below the brake and clutchreservoirs. If you're thinking of changing it (it's not difficult) first drain the sump, then you need to take off the airbox lid and trunking,disconnectingthe air flow meter and remove the engine cover. You then unscrew the top of the housing with a 27mm socket- I needed a universal joint as the clutch reservoir gets in the way- and lift away, then retrieve the filter from the housing. Then under the car you need to undo the 17mm bolt at the base of the filter and drain the housing. The refit the bolt. Replace the rubber seal in the cap (included with the filter), refit the filter and screw up the top of the housing, tightening top the correct torque. Re fill with the correct grade of fully synthetic oil (5w/40, AECA C3 if you still have your DPF in place), start and allow to idle (having replaced the wire to the air flow meter to prevent the MIL coming on), recheck oil level, top up if required and you're done. Don't forget to reset the oil life indicator by switching on the ignition. depressing the accelerator to the floor 3 times within 10 seconds and then switching of the ignition!
