The tire pressures in an Audi S4 are shown by the TPMS in either the instrument cluster or the MMI/Virtual Cockpit; you will see each tire's current pressure and the vehicle's recommended cold pressure.
This guide explains where to find the tire pressure readouts on common Audi S4 configurations, how to read them, and what to do if a warning appears. It covers older models with a traditional instrument cluster as well as newer cars with the Virtual Cockpit and updated MMI.
Where to view tire pressure in the Audi S4
TPMS data appears in two primary places depending on model year and trim: the instrument cluster (the gauge cluster behind the steering wheel) and the vehicle's MMI/Virtual Cockpit. Below are the typical paths for each configuration.
Via the instrument cluster (Driver Information Display)
Use the device’s original dashboard display to quickly check each tire’s current pressure without navigating menus.
- With the engine on or ignition on, press the View button on the steering wheel to cycle through the instrument cluster screens until you reach the Tire Pressure screen that shows all four tires.
- Read the pressures displayed for front-left, front-right, rear-left, and rear-right tires (watch for the unit shown, psi or bar).
- Refer to the door jamb sticker on the driver's door frame to confirm the recommended cold inflation pressures for front and rear tires.
- If a tire is low, inflate it to the recommended value and recheck. If a TPMS warning light is on, inspect for a puncture or slow leak.
- Note that readings can update after driving or temperature changes; if necessary, drive a short distance and recheck.
Using the instrument cluster method is quick and doesn’t require navigating the MMI. It’s handy for a fast check during routine stops.
Via the MMI / Virtual Cockpit (latest models)
For a centralized view or to monitor all tires at once, use the MMI or Virtual Cockpit navigation to access tire pressures.
- With the car on, access the MMI/Virtual Cockpit by pressing the Car button (or equivalent) on the center console or steering wheel.
- Navigate to Tire Pressure, Tire Inflation Pressure, or a similar Tire Monitoring option. Labels may vary by model year (e.g., "TPMS" or "Tire Pressure Monitoring").
- View the live readout for all four tires; the screen usually shows current pressures and the recommended cold pressures per tire.
- If a tire is significantly under the target, inflate to the recommended value and recheck all four readings.
- Exit the menu when finished. The TPMS will recalibrate after driving or temperature changes.
The MMI/Virtual Cockpit method is beneficial when you want a single, centralized view of all tire pressures and to compare them side-by-side.
Practical tips for reading and using TPMS data
Interpreting the numbers and taking action in a timely manner keeps you safe and improves fuel efficiency and tire wear.
- Tire pressures are typically shown in psi or bar; confirm the units in use on your readout to avoid misreading values.
- The recommended pressures come from the door jamb sticker and may differ between front and rear tires depending on load and speed rating.
- When inflating, do so from cold (before driving) to get an accurate target pressure. Recheck after driving a few miles, as tires heat up and pressures rise.
- A TPMS warning light indicates at least one tire is below the threshold; inspect all tires and inflate as needed.
- If a wheel sensor is faulty or a tire is unusually leaking, the TPMS may still show readings that don’t reflect the actual pressures until repaired.
Regular checks prevent under-inflation risks and help maintain performance and safety.
Troubleshooting and notes
If you notice inconsistent readings or the TPMS warning light remains on after inflation, it may indicate sensor or system issues. In such cases, have the system inspected by a qualified technician, especially if you recently serviced the wheels or replaced a tire.
Summary
To view tire pressure on an Audi S4, use either the instrument cluster’s Tire Pressure screen or the MMI/Virtual Cockpit’s Tire Pressure menu, depending on your model year. Read the current pressures for all four tires and compare them to the recommended cold pressures found on the door jamb sticker. Inflate under-inflated tires and allow the TPMS to recalibrate after driving. For ongoing monitoring, the MMI/Virtual Cockpit offers a consolidated view, while the instrument cluster provides a quick, on-the-go check.
