BMW uses direct TPMS (RDC) on most models — reset is via iDrive after inflating, then drive for a few miles for the system to confirm.
Why the BMW tyre pressure light is on
BMWs use proper wheel-mounted pressure sensors (RDC — Reifendruckkontrolle). When the warning comes up it's either a real pressure loss, a sensor with a dying battery (typical lifespan 5–7 years, so very common on 2017-and-older cars), or you've just had tyres changed and the system needs a relearn.
BMW tyre pressure light reset — step by step
- Inflate all four tyres cold to the placard pressures (inside driver's door pillar).
- Start the engine — RDC needs the car running for the reset.
- On iDrive cars (F-series and newer): iDrive → CAR / Vehicle Info → Vehicle Status → Tyre Pressure → Perform Reset (or 'Reset').
- Confirm the reset — the system will say 'Reset in progress'.
- Drive away normally. After about 5–10 minutes of driving over 15mph, the message will change to 'TPM status: active'.
- On older E-series without iDrive (E90, E60, E70): press and hold the RDC button (next to the hazard switch) for about 5 seconds until the indicator light flashes.

If the light won't go off
If the warning says 'TPM Malfunction' or 'TPM Sensor Failure' (rather than just 'Low Tyre Pressure'), one of the four sensors is dead or has lost contact. A BMW-specific scan tool will tell you which wheel. New sensor + valve service kit + balance is the fix — refusing to do it means MOT advisory and the warning will never clear.
What it costs
DIY reset is free. RDC sensor replacement: £40–£80 per sensor for aftermarket (Schrader, Huf), £90–£160 for genuine BMW. Always do the sensor service kit (valve, seal, nut) at the same time — £8–£15 extra and avoids a comeback for a slow leak.
Bob's workshop tip
If your BMW is 2018 or older and has had new tyres on the original sensors more than once, just budget for a new set of sensors at the next tyre change. Replacing 4 in one visit (while tyres are off anyway) is a third of the price of doing them one at a time as they fail.

What Bob keeps in the boot
A pump puts air back in, but it will not seal the hole. For a nail or a screw in the tread, the repair itself is the Emergency Puncture Repair Kit — £9.99 with free UK delivery: rubber rope plugs, reamer, T-handle tool and rubber solution, posted from the workshop in Birnam, Dunkeld. If you would rather not take a wheel off at the roadside, the quick-fix tyre repair spray is the no-tools option. Keeping the pressures right in the first place is covered in tyre pressures by registration and resetting the tyre pressure warning light, and the pump itself in Bob's electric tyre pump picks.
Be straight about what a plug is: a get-you-home repair for small punctures in the central three-quarters of the tread. Never plug sidewall or shoulder damage, drive gently afterwards, and have the tyre inspected or replaced by a tyre specialist as soon as you can.
