Audi A6 Tyre Pressure

What is the recommended tyre pressure of an Audi A6?

The recommended tyre pressure levels of your Audi A6 varies model to model, but generally it sits at around 32-33 psi in all four tyres.

A full Audi A6 tyre pressure guide can be found in your owner’s manual, with the recommended values also noted in the tyre placard (stuck on your driver’s door interior).


Where can I check my Audi A6 tyre pressure?

Audi A6 tyre pressure can be checked by a mechanic at a garage or at a petrol station, where you can also amend pressure.

You can also gather pressure readings at home with a handheld pressure gauge.

The process for checking pressure levels is to:

Remove valve cap from your tyre

Place gauge onto the valve stem and push down until hissing noise stops

Your gauge will now show a reading, note this down

Reattach the valve cap and repeat process for the three remaining tyres.


What should I do once I see a tyre pressure warning?

As soon as the tyre pressure warning light illuminates on your Audi dashboard, the first thing to do is to check tyre pressure of all your wheels.

The light should then go out once you drive away again, if the light remains on cease driving as soon as if safe.

The light is likely remaining on because you either have a puncture or the warning light itself is faulty and may require a reset.


How do I reset a Audi A6 tyre pressure light?

Firstly, ensure the pressure levels are correct on all four of the Audi A6 tyres.

Now, turn your ignition on but refrain from starting the engine.

Press car function button (found on MMI control panel).

Next, select the Systems control button, then “Servicing and Checks”.

You must then select “Tyre Pressure Monitoring” followed by “Store Tyre Pressures”.

Finally, select “Yes, Store Now”.


Bear in mind that the TPMS reset process will vary model to model and will always be noted in your owner’s manual if you are in anyway unsure.

The check engine light, also known as the malfunction indicator light, illuminates when there is an issue with your Audi A6 engine, transmission or emissions system.
