Audi Check Engine Oil Level & Add

Keeping the oil topped up is one of the few pieces of maintenance an Audi owner can do in five minutes with no tools. This guide covers reading the level on models that still have a dipstick, checking it through the MMI on models that do not, and adding oil correctly. One warning before you start: if the red oil pressure light is on, this is not the fix. That light means the engine is not receiving oil at pressure, and adding oil to a system that is not circulating it will not help. Switch the engine off as soon as it is safe and have it looked at, because the damage is measured in minutes.

The oil dipstick lets you check the engine oil level on most Audi vehicles. Audi engine oil level can also be checked via the instrument cluster or MMI on some models.

The first set of instructions applies to Audis with oil dipsticks. If your Audi does not have an oil dipstick, you must check the engine oil level via the Multi-Media Interface (MMI).

Procedure

1. Park the Audi vehicle on a level surface and apply the parking brake.
2.   Turn off the engine and wait at least three minutes before you check the engine oil level on your Audi. The engine oil can return to the oil pan, and a correct reading can be obtained. 
3. Open the hood of your Audi by pulling the hood release under the dash. The hood release is on the driver’s side.
4. Locate the oil dipstick on the side of the engine. The oil dipstick has a yellow handle. Oil dipstick on an Audi with a 3.2L engine.
5. Remove the dipstick by pulling it up.
6. Use a clean cloth to wipe off any oil that may still be on the dipstick.
7. Note the minimum (LOW) and maximum (FULL) marks before reinserting the dipstick back into the engine block.
8. Reinsert the dipstick into the tube. Make sure to press it in.
9. Remove the dipstick.
10. Read the oil level. The level needs to be between the min and max mark.
11. If the engine oil level is below the minimum mark, you need to add engine oil to your car. If the level is significantly above the FULL mark, you need to remove oil from the engine. If you overfill your Audi engine with oil, you can cause engine and catalytic converter damage.

These instructions work on all models with a dipstick, including Audi A3, A4, A6, A7 Q3, Q5, and Q7. Newer Audi vehicles like this Audi Q5 with a TFSI engine have no dipstick to check the engine oil level.

If that is the case with your Audi, you can check the engine oil level via the instrument cluster. Follow the instructions below to learn how to check the Audi oil level via the infotainment system.

Check Audi Oil Level via MMI

Check Audi oil level via the dashboard MMI or voice system.

1. Power on the car, but do not start the engine.
2. Press MENU in the center console.
3. Go to CAR
4. Go to Servicing and Checks.
5. Check the oil level.
6. Wait a few seconds.
7. Engine oil level OK will show on the screen with the level bar.

Notes

• Note that the measurement will be inaccurate if the vehicle is not on a level surface.
• If the sensor is defective or there is a malfunction, you may get an error message stating:
  • “There is currently no information available on the engine oil level. “

How to add engine oil

Only use the recommended Audi engine oil as your owner’s manual.

1. Locate the oil filler cap.
2. Unscrew the cap from the oil filler opening.
3. Add recommended grade engine oil.
4. Add only a quart at a time, wait a few minutes, and recheck the level.

Add more engine oil if the oil level is still under the MIN mark. Don’t overfill the engine with oil. The oil level should not be above the MAX or FULL mark on the dipstick. Overfilling the engine with oil can cause problems or damage the catalytic converter.

Yellow oil can light and red oil pressure light are not the same

Audi uses two different warnings and confusing them is expensive. The yellow oil can symbol, often with a message asking you to check the oil level, means the level sensor has seen the oil drop and topping up is exactly the right response. The red oil can symbol means low oil pressure, which is a mechanical fault with the pump, a blocked pickup or worn bearings. Driving on with the red light will destroy the engine, and no amount of oil poured into the filler will change that.

Check it warm, level and after it has settled

Audi oil level readings are only accurate on level ground with the engine at operating temperature and switched off for a few minutes so the oil has drained back to the oil pan. Checking immediately after switching off reads low, and checking on a slope can read a full liter out either way. On models with no dipstick the MMI will simply refuse to give a reading until those conditions are met, which is why the measurement sometimes appears to be unavailable.

Using oil between services is normal up to a point

Audi considers consumption of up to around half a liter per thousand kilometres to be within specification on many engines, so needing a top up between services is not automatically a fault. What is worth investigating is a sudden change. If an engine that never needed oil now wants a liter every few weeks, or you see blue smoke on start up or oil pooling on the undertray, that points to valve stem seals, piston rings or a leak rather than normal use.

The oil specification matters more than the brand

Audi engines call for a specific VW oil standard such as 504 00, 507 00 or 508 00 rather than just a viscosity grade, and the required one is printed in the handbook and often on the oil cap. Using an oil that meets the right standard from any reputable brand is fine, but using an oil that does not meet it, even an expensive one, can block a particulate filter or shorten the life of the timing chain tensioners.

Frequently Asked Questions

How do I check the oil level on an Audi without a dipstick?

Many newer Audis have no dipstick. Read the oil level in the MMI or the instrument cluster vehicle menu.

When should I check the oil level on an Audi?

Check it on level ground with the engine warm, after it has been switched off for a few minutes so the oil settles.

What oil should I add to my Audi?

Use oil that meets the VW standard listed in your owner’s manual, such as VW 504 00 or 508 00. The specification matters more than the brand.

What is the difference between the yellow and red oil lights?

The yellow oil can light means the level is low, so top it up. The red oil pressure light means stop the engine right away; adding oil is not the fix.
