If the tyre-pressure warning has come on in your Alfa Romeo 159 (2005–2012) after you’ve adjusted the pressures or changed a wheel, you reset it by storing the new pressures and driving for a few minutes. Here’s how.
When to Reset
- After checking or adjusting the tyre pressures.
- After changing wheels or tyres, or fitting winter wheels.
Resetting the System
- Park level and set all four tyres to the correct cold pressures (placard in the driver’s door shut).
- Switch the ignition on and confirm/reset the tyre-pressure setting in the menu if your 159 offers one.
- Drive for about 5 minutes at over 20 km/h (12 mph) — the new pressures are then stored as the baseline.
If the Warning Stays On
- Recheck every tyre — one below spec keeps the warning on.
- Complete the learn drive — a very short trip may not be enough.
- After a wheel change, make sure pressures are exactly to spec before driving.
- Still showing with correct pressures? A fault may be stored — look it up on autodtcs.com.
Frequently Asked Questions
How do I reset the tyre pressure light on an Alfa Romeo 159?
Set the pressures, confirm in the menu if offered, then drive about 5 minutes above 20 km/h to store them.
Why won’t the warning clear?
Usually a tyre still below spec, or the learn drive wasn’t long enough.
Do I need a tool?
No for a normal reset; a tool is only needed if a pressure sensor is replaced.
Does adjusting one tyre need a full reset?
Yes — set all four correctly first, then do the learn drive so the baseline is right.
If the warning came on with other lights, decode the code on autodtcs.com.
