The 2015 Audi A5 generally uses an electronic oil level sensor that reports the oil level to the instrument cluster or MMI, so there is usually no traditional dipstick. You check the level by warming the engine and reading the oil level in the MMI; in some markets a dipstick may still be present, but the electronic readout is the standard method.
Check the oil level with the MMI (electronic level)
Use the vehicle’s onboard computer to read the oil level. Ensure the engine is up to operating temperature and the car is on level ground before checking the reading on the MMI.
- Start the engine and let it reach normal operating temperature (the oil should be warm to the touch and the engine at running temperature).
- Park on level ground and keep the engine running. Access the oil level readout in the MMI (the path can vary by software version, commonly Car > Servicing & Checks > Oil Level).
- Read the displayed result. The screen may show a status such as OK or a numerical value. If the readout is unavailable, repeat after the engine has warmed up, or consult the owner’s manual for your software version.
- If the level is low, top up with the correct oil grade through the engine oil filler neck and recheck after the oil has circulated.
Using the MMI to monitor oil level helps ensure accuracy and avoids overfilling. If the reading seems inconsistent or you see an oil warning, contact a dealer or technician for a check.
Oil dipstick method (if applicable in your market)
Some markets or specific trims may still include a traditional dipstick. If your 2015 A5 has one, use these steps to verify the level.
- Park on level ground, engine off, and wait 5–10 minutes for the oil to settle in the sump.
- Open the hood, locate the dipstick, pull it out, wipe it clean, reinsert fully, then pull again to read the level using the marks on the dipstick.
- If the level is low, add oil in small increments, wait a moment for it to settle, and recheck until the level sits between the minimum and maximum marks.
Note: If you’re unsure whether your car has a dipstick, check the owner’s manual or ask a dealer. Many 2015 A5 models in the US and other markets rely primarily on the electronic oil level sensor.
What to do if the oil level is low or readings are uncertain
A low level should be corrected promptly with the proper oil grade. If readings are inconsistent, or you notice oil consumption that seems abnormal, have the vehicle inspected by a qualified technician to rule out leaks or sensor issues.
Summary
For a 2015 Audi A5, the standard method to check oil level is through the electronic sensor readout in the MMI, ensuring the engine is warm and the car is on level ground. If your model has a dipstick, you can use it as an alternative, following the same precautions. Always use the recommended oil grade and avoid overfilling. When in doubt, consult the owner’s manual or contact a dealer for guidance.
