If the tyre-pressure warning has come on in your Porsche Macan (2014–present) — the 95B — after you’ve adjusted the pressures or changed a wheel, you handle it through the central display (PCM). The Macan uses sensors in the wheels, so the warning is simply telling you the live readings no longer match what the car expects — it’s a prompt, not a fault. A quick top-up may clear on its own, while a wheel or tyre change needs you to confirm the new profile. Here’s how both cases work.
How It Works on the Macan
The 95B Macan runs a direct system: each wheel carries its own pressure sensor that reports to the car, so the PCM can show the actual reading at every corner rather than estimating from wheel speed. Because the readings are live, correcting a slightly low tyre often clears the warning on its own once the sensors report during a drive. A wheel or tyre change is different — you tell the car which wheel/tyre profile is fitted (for example a seasonal set or a different size) so it monitors against the right expected pressures.
Before You Start
- Check and set pressures cold, before driving, so heat doesn’t inflate the reading.
- Use the figure on the driver’s door-pillar label, matched to your load and the tyres fitted.
- Set all four corners correctly — the live display makes it easy to see which is low.
- After a seasonal swap, know which wheel/tyre profile to select (summer/winter or the size fitted).
- Allow a few minutes of driving so every sensor can report.
After Adjusting Pressures
For a simple top-up, no manual reset is needed — just drive the car and the system re-reads the corrected pressures.
After Changing Wheels or Tyres
- Set all four tyres to the correct cold pressures.
- On the PCM / multifunction display, open the tyre-pressure page.
- Select the correct wheel/tyre setting (e.g. summer/winter or the size fitted).
- Drive the vehicle to complete the procedure — the warning clears once confirmed.
If the Warning Stays On
- Recheck every tyre. One below spec keeps the warning on — the live page shows which corner.
- Pick the matching wheel/tyre profile after a seasonal swap so the car monitors the right pressures.
- Drive a few minutes so the sensors report — the light may not clear the instant you set off.
- Cold morning? Pressures drop as temperature falls; top up to the label figure and drive.
- Slow puncture. If one corner keeps dropping, look for a nail or a leaking valve rather than a system fault.
- Spare or space-saver — if fitted temporarily, its pressure and sensor status can affect the display.
- Still showing with correct pressures? A sensor may have a flat battery — look up the code on autodtcs.com.
What to Expect After
Once the corrected pressures are read on a short drive — or the right wheel/tyre profile is selected after a swap — the warning goes out and the PCM shows a normal reading at each corner. It should stay off for the trip and beyond. A light that returns on a cold night is usually just seasonal pressure loss: top up and drive. One that comes back quickly, or with the pressures confirmed correct, points to a genuine leak or a tired sensor rather than a reset that didn’t take.
Frequently Asked Questions
How do I reset the tyre pressure warning on a Porsche Macan?
After a top-up just drive and the system re-reads the corrected pressures. After a wheel or tyre change, set all four cold, select the correct wheel/tyre profile on the PCM tyre-pressure page and drive a few minutes to confirm. The warning clears once the sensors have reported.
Does the Macan have sensors in the wheels?
Yes — it’s a direct system, so each wheel has its own sensor and the display shows the actual pressure at every corner. It also means a sensor with a flat internal battery can keep the warning on even when the pressures are correct.
Why won’t it clear?
Usually a tyre still below spec, or the wrong wheel/tyre profile selected after a wheel change. Recheck all four against the label, make sure the fitted profile is chosen, then drive a few minutes so every sensor reports.
Do I need a tool?
No for a normal reset — adjusting pressures and driving, or selecting the fitted profile after a swap, is all it takes. A tool is only needed if a sensor is replaced and has to be matched to the car.
Why does the light come on in cold weather?
Air pressure falls as the temperature drops, so on a cold morning the tyres can read low enough to trip the warning with no leak present. Set each corner back to the label figure while the tyres are cold, then drive a few minutes and it clears.
Do I need to reselect the profile after every seasonal swap?
Yes, if you fit a different wheel or tyre set the car should be told which profile is now on it, so it monitors against the right expected pressures. Skipping that can leave the warning on or let it judge the tyres against the wrong reference.
If the warning came on with other lights, decode the code on autodtcs.com.
