7 Hidden features & tips for your Audi A4

Let’s check out some amazing hidden features and tips for the Audi A4!

1. Open all windows automatically with your key fob

Every Audi A4 owner uses their key fob to open and close the car.

What many of them don’t know is that you can use your key fob to close or open all the windows automatically and even the sunroof if your A4 has one!

This is an excellent tip if you want to get some fresh air into your car quickly or if you want to cool down the interior on a hot day.

So, here’s how to do it:

  • Press and hold the ‘Unlock’ button on your key fob to open all windows (and the sunroof if you have it).
  • Press and hold the ‘Lock’ button on your key fob to close all windows (and the sunroof if you have it).

2. Turn off the beeping sounds when you open the door with the ignition on

Tired of those long beeps that start when you open your door while the ignition is turned on?

Don’t worry; we have the solution.

On the bottom of your wiper stalk, there is a small ‘Reset’ button.

Press it a few times, and the annoying beeping noise will instantly stop!

3. Let the passenger side mirror pivot down automatically when in reverse

The next tip is particularly useful when parallel parking.

Did you know that you can automatically let your passenger side mirror pivot down when in reverse?

This will allow you to see any curbstones and prevent you from damaging your wheels!

You can enable this feature by ensuring your mirror adjuster button is set to the passenger’s side.

So, if you have a left-hand drive car, ensure the mirror adjuster button is set to the right, and your passenger side mirror will automatically pivot down when reversing.

4. Launch control

The Audi A4 offers drivers a unique feature for race-level performance: launch control.

Activating launch control allows drivers to get maximum acceleration and performance when starting the car from a standing stop.

It works for any Audi A4 with an automatic transmission from the B9 generation (2015 – present) onwards.

To activate launch control on your Audi A4, follow these six steps:

  1. Start up your engine.
  2. Put the transmission in sport (S) mode.
  3. Turn off the traction control by long pressing the traction control button.
  4. Put your left foot on the brake.
  5. Floor the gas pedal all the way.
  6. The engine will rev up and hold its speed at roughly 3,100 RPM.
  7. Release the brake pedal.
  8. And you’re off!

5. Unleash your A4’s hidden powers with RaceChip

While it’s not always needed, having more power in your car is definitely more fun, right?

So, if you are looking for ways to increase the power of your Audi A4, chip tuning could be the perfect way to bring it to the next level.

And it doesn’t have to be hard to do it – all it takes is plugging a device into the car’s diagnostic link connector, revealing several engine options from which to choose.

From there, it’s just a matter of selecting one and watching as your newly-customized vehicle takes on a whole new level of power!

RaceChip is a great company that develops easy-to-install tuning boxes for Audis and most other manufacturers.

7. Automatically put the transmission in ‘Park’ when turning off the car

The last hidden feature of the Audi A4 is that it automatically puts the automatic transmission in ‘Park’ when you turn off the car.

So, if you have your automatic transmission in ‘Drive,’ and you arrive at your destination, you can turn off the engine, and the car will go into ‘Park’ automatically!

This feature is beneficial if you’re parked on an incline, as it will prevent the car from rolling away. But also, it’s just more convenient not having to press the ‘Park’ button every time.

And here’s another bonus feature – if you have your automatic transmission in sport or manual mode and you turn off the car, the gear leaver will also automatically pop back into the central position!
