Follow these steps carefully
The 2015-2018 Q3's 2.0L TFSI takes roughly 5 quarts (4.6-5.0L) of full-synthetic VW 502 00 oil — 5W-40 is the common choice, 5W-30 also approved. Top-mounted cartridge — buy the EA888 element kit with a new housing O-ring, plus a new drain-plug washer.
Idle two to three minutes so the oil thins, then shut off. Remove the undertray fasteners (a mix of T20/T30/T45 Torx and 19 mm belly-pan bolts — keep them sorted) to expose the drain plug. Remove the filler cap so the crankcase vents.
Remove the drain plug and let the oil drain until it slows to an occasional drip. Reinstall the plug with a NEW washer and tighten it to 30 Nm - the Audi spec, so use the torque wrench. Move to the top of the engine: fit the 32 mm socket on the filter housing cap and unscrew it. Lift out the old cartridge element, note its orientation, and wipe the housing clean. Seat the new element exactly as the old one sat and install the NEW O-ring, coating it lightly with fresh oil so it seals without pinching.
Set a funnel in the filler neck and pour in 4.5 liters of VW 502 00 oil to start - deliberately short of the full capacity. Wait a full minute, then check the dipstick and add the remainder in small pours until the level sits at the full mark. This fill-then-check approach is the safe method on the Q3, since listed capacities vary slightly across the 2.0T variants - the dipstick is the final authority. Reinstall the filler cap, refit the undertray with all of its fasteners, and lower the vehicle to level ground. Rushing the pour is how oil ends up on the engine cover instead of in the engine - feed it slowly.
Wait two to three minutes for the oil to settle, then verify the dipstick twice: pull, wipe, fully reinsert, read. The level should be at the full mark, never above. Start the engine and idle for 30 to 60 seconds, watching the oil-pressure warning go out and looking underneath for drips at the drain plug and around the filter housing. Shut it off, wait two minutes, and confirm the final dipstick reading. Reset the service-interval reminder through the vehicle menus per the owner's manual.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
