If the tyre-pressure warning is on in your BMW 1 Series Mk3 (F40, 2019–present) after adjusting pressures or changing wheels, you set the current pressures as the new reference through iDrive, then confirm with a short drive. Here’s how.
Set the Pressures First
Inflate all four tyres cold to the figure on the label in the driver’s door opening (BMW lists pressures by load — use the right values).
How to Reset the F40 TPMS
- With the ignition on, open iDrive and go to the ‘CAR’ / Vehicle menu.
- Select ‘Tyre Pressure Monitor’ (tyre pressures).
- Choose ‘Perform Reset’ / ‘Reset’ and confirm.
- Drive off — the system learns the new pressures as you drive and the warning clears.
If the Warning Stays On
- Re-check every tyre, including the spare if it’s a monitored full-size wheel.
- One tyre keeps dropping — look for a slow puncture; the system is doing its job.
- A steady-flashing TPMS light points to a sensor fault and needs a tyre shop’s tool.
Frequently Asked Questions
Where is the tyre-pressure reset on the F40?
In iDrive: CAR/Vehicle → Tyre Pressure Monitor → Perform Reset, then drive.
Do I need a tool?
Not for a normal reset — set the pressures, reset in iDrive, and drive. A tool is only needed if sensors were replaced.
Why did the light come on in the cold?
Pressure drops with temperature. Top up to the door-label figure and reset.
The light keeps flashing — low pressure?
A persistent flash usually means a sensor fault rather than low pressure — have the sensors checked.
If a fault code is stored, look it up on autodtcs.com. To clear a service reminder, see our 1 Series F40 service reset guide.
