Tools Needed:
- Wrench or socket set
- Oil filter wrench (if needed)

- Replacement O-ring (if necessary)
- Drip pan or old newspaper
- Funnel
- New oil (check your owner's manual for the correct type and amount)
Instructions:
1. Prepare the Vehicle: Park the Audi A4 on level ground, turn off the engine, and allow it to cool down. Engage the parking brake and chock the wheels to prevent the car from rolling. Open the hood of the vehicle.
2. Locate the Oil Filter Housing: The oil filter on the Audi A4 V6 is located on the top of the engine. Look for a cylindrical housing with a black cap. The oil filter housing is usually near the back of the engine.
3. Remove the Oil Filter Housing Cap: Use a wrench or socket to loosen and remove the oil filter housing cap. Be careful as some oil may spill out. Place a drip pan or newspaper underneath to catch any dripping oil.
4. Remove the Old Oil Filter: Once the oil filter housing cap is removed, you will see the oil filter inside the housing. Use an oil filter wrench (if necessary) to loosen and remove the old oil filter. Be careful not to spill any oil.
5. Inspect the Oil Filter Housing and O-Ring: Check the oil filter housing and the O-ring for signs of damage or wear. If the O-ring is damaged or worn, replace it with a new one.
6. Install the New Oil Filter: Before installing the new oil filter, apply a thin layer of new oil to the gasket. Screw the new oil filter into the oil filter housing until it is snug. Do not over-tighten the oil filter.
7. Replace the Oil Filter Housing Cap: Once the new oil filter is installed, replace the oil filter housing cap. Hand-tighten the cap until it is snug, then use a wrench or socket to tighten it further.
8. Refill the Oil: Use a funnel to add new oil to the engine through the oil filler cap. Refer to your owner's manual for the correct oil type and quantity.
9. Check the Oil Level: Use the dipstick to check the oil level and ensure it is between the "full" and "add" marks.
10. Start the Engine and Check for Leaks: Start the engine and let it run for a few minutes. Check underneath the car for any oil leaks. If you notice any leaks, tighten the oil filter housing cap or oil drain plug until the leak stops.
Note: If you are not comfortable performing this task yourself, it's best to have the oil filter changed by a qualified mechanic.
