- Oil leak!!
A Blog for Audi Addicts
An oil change is an important part of your car’s maintenance regimen. Because of the synthetic oil used on many modern Audis, the recommended interval is 5000 miles. The B7 oil change is slightly more involved than the B6, but in many ways it’s more efficient, and most definitely less messy. It may seem daunting, but it’s quite an easy process. Audiction took advantage of a beautiful, warm March day to prepare a detailed DIY to help guide you through your first oil change on your 2.0T. Before you know it, you’ll be a pro! Some of the items are interchangeable; what’s listed is what we used.
Drive the car to warm up the engine oil. About 15 minutes of driving is sufficient to get the oil warm. We added a bottle of Motul Engine Clean to degunk the engine a bit. If you choose to follow this, you can add this and let the car idle for 15 minutes instead of driving it. We found the oil to be warm enough.
Drive the car onto ramps or put it on jack-stands. Make sure the car is secured properly before climbing underneath.
Remove the belly pan using the flat head screwdriver.
Open the hood and remove the oil cap to let the pressure in the crankcase escape. This should go without saying, but make sure your car is off before removing the oil cap. Set the cap aside and carefully clean around the hole into the crankcase (if it’s dirty). Be careful not to let any dirty or debris fall in.
Locate the engine oil filter. It is on the driver’s side of the engine right above the motor mount. Unscrew the protective cap on the bottom of the oil filter. From underneath the car, screw the head of oil filter housing drain tube into the bottom of the filter until you feel resistance. Then connect the hose, making sure the line is pinched. Continue to screw until you hear the click of the drain valve. Oil should start to drain down the hose. Un-pinch the hose and let it drain into your drain pan. When it’s done, re-pinch the hose and let it catch whatever else drips out.
Climb under the car. If you’ve never done an oil change before, it’s a good idea to lay a piece of cardboard down under the oil pan. Grab your ratchet and 19mm socket. The drain plug is on the passenger side of the car. Make sure the socket is seated properly and steadily apply pressure until the initial bond breaks. For the most part, you should be able to unscrew the bolt by hand (be careful, the oil pan is probably still very warm).
Grab your drain pan and hold it up close to where the drain plug is. Continue to unscrew the plug. You’ll start to see oil drip out, and you’ll start to get a sense of where the end is. When the plug finally releases, let it drop into the drain pan. By holding it close to the plug, hopefully you’ve caught the initial jet of oil and it hasn’t sprayed all over your driveway. You can lower the pan to the ground; just gauge where the oil flow is going. As it slows, it will trickle out. Let the oil drain out for about 10 minutes or so.
Go back to the engine oil filter. Drain any remaining oil and unscrew the hose and head. Use the oil filter socket (you may need an extension), and unscrew the oil filter from under the car. Once you break the initial bond, you should be able to unscrew it by hand. Remove the assembly, and drain any oil into the drain pan. Discard the old filter.
Take your new filter and seal out of the box. Note how the old seal is situated on the filter housing (there’s a little tab sticking up, use that to gauge its relative position). Remove the old seal, dab the new seal with some of the used engine oil, and reinstall it. Put the new filter in the housing and screw it back into position. You may need to apply some pressure to help it catch the threads, but once it catches, it should screw on effortlessly. Use the torque wrench and tighten the filter to 25 nm (neuton meters). Reinstall the protective cap.
Screw your new oil drain plug into the oil pan. Screw it in by hand so you don’t cross-thread it. When it’s tight, use a torque wrench and tighten to 30 nm (neuton meters). If you don’t have access to a torque wrench, tighten it with a ratchet just to the point that you feel resistance, and then give about a quarter turn.
Add your engine oil. The 2.0T has a capacity of 4.5L of oil. Add it slowly through the hole in the crankcase. If you’re unsure of exactly how much to add, err on the side of caution and add less (you can always add more, but it’s a pain to take oil out). Make sure the cap is on tight.
Start the car and check for leaks. If there are none, reinstall the belly pan and put the car back on the ground. After the car has run for ~10 minutes, check the oil level and adjust as necessary. Dispose of the old engine oil properly (I put it in the oil containers that are now empty, a funnel helps greatly here). Local laws differ, but most gas stations or places that sell oil will take your old oil from you.
