How To Reset the Low Oil Pressure Warning Light on Your Audi Q5

Noticing the low oil pressure warning light glowing or flickering on the dashboard while driving your Audi Q5 can be a bit disturbing. However, it doesn’t always indicate severe ongoing issues. Sometimes, a minor glitch in the oil system or a false signal from the sensor also triggers this warning, frustrating you at the end of the day. So, how to diagnose and reset the warning light? Well, this particular article explains the techniques to reset the illuminating low oil pressure alert light and the tricks to perform when the light still stays on even after resetting it.

What is the purpose of your Audi Q5 low oil pressure light?

There is no point in learning to reset the oil pressure warning light without understanding its meaning and cause. This alert is related to your vehicle’s oil system. Thus, when this alert turns on, it indicates a lack of oil in the engine or something is wrong with the oil pressure sensor or pump. If your car is facing these issues, you must take immediate action to resolve the trouble since a low engine oil or faulty oil pressure sensor or pump can impact the engine, degrading the overall vehicle efficiency. But sometimes, this warning light could simply be a false alert or a minor problem that can be fixed easily. So, let’s learn how to detect minor oil system troubles and how to reset the false warning light so that you can get rid of this inconvenience.

Inspect the oil levels

Low engine oil can truly affect the engine. So, whenever there is insufficient oil in the oil pan, it is usual to get these warnings. So, before performing the steps to reset the alert, you must check the engine oil level and add more if required. Mentioning below the process to do the same:

 Park your car on a flat surface to measure the oil level correctly.

 Turn off the engine and let the oil settle down perfectly.

 Open the hood and find the dipstick, which usually looks like a yellow or orange handle close to the engine.

 Remove the dipstick and clean it thoroughly with the help of a clean rag or paper towel.

 Put it inside the tank and take it out again after a few minutes to get an accurate reading.

If you observe the dipstick reading to be below the lower limit, you need to add more oil to the tank. Make sure to use the right type of oil suitable for your Audi Q5. However, if there is enough oil inside the tank, there might be something off with the oil pressure system itself.

Search for oil leaks

Sometimes, the oil leaks also trigger this alert. Thus, you must check the seals, gaskets, or drain plugs for any signs of wear and tear. Because these are the component that usually ruptures or loosens and escape oil through them. You may also check the engine compartment or the area below your car for any oil marks or puddles. If you get any evidence of oil drips, you must seek professional assistance to fix the leaks by replacing the damaged part with a new one.

Check the oil pressure sensor

When the oil pressure sensor malfunctions, it can also make this warning light appear on the dashboard. This sensor is responsible for monitoring the oil pressure in the engine and transfers the data to the instrument cluster to turn on the alert light. Thus, when this sensor fails, it can send wrong information, and as a result, the warning light glows even if the oil pressure is normal. Since the sensors are complex auto parts, it's better to leave these issues for an Audi expert to handle.

Reset the warning Light

If you are done with all the above DYI fixes and still see the alert appearing on the dashboard, it's time to go for resetting the warning light. There are three ways to reset the light, which are mentioned below:

 Using the vehicle’s infotainment system: Power up the car without starting the engine and let all the warning lights glow. Touch the “Car” button on the infotainment display to see the car menu. Next, visit “Settings” or “Vehicle Settings”, according to the model. Go down and select “Oil Pressure Warning”. Follow the on-screen instructions to reset the alert.

 Using the steering wheel controls: Turn on the ignition, but don’t crank the engine. Select the “Menu” button on the steering wheel. Go to “Car” and choose “Settings” or “Vehicle”. Click the “Reset” option for the oil pressure warning light and confirm the same.

 Detach the battery: Even after performing the above two methods, if you still see the warning, then turn off your vehicle. Disconnect the negative battery terminal and wait for a few minutes before reconnecting it. Next, start your car.

Finally

The low oil pressure warning light appearing on your Audi Q5 dashboard can be pretty challenging, but it doesn’t always indicate serious trouble. However, if the light stays on even after following all the above inspection and resetting processes, it means some other part is the real culprit. So, it’s recommended to consult a skilled mechanic to troubleshoot the issue precisely using his diagnostic tools and repair or replace the faulty component to get everything back on track.
