The short answer
Yes — for the vast majority of cars, vans, 4x4s and motorhomes, a mobile fitter can replace TPMS sensors and reset the system. A small number of vehicles need a dealer-specific OBD relearn that goes beyond what most mobile setups carry. I'm honest about that on the phone before I quote.
If you've got a dashboard tyre-pressure warning light that won't clear, or you're due new tyres on a TPMS-equipped car, this page tells you what's involved, what I can do, and where the boundary sits.
What TPMS actually is
TPMS — Tyre Pressure Monitoring System — has been mandatory on new cars sold in the UK since 1 November 2014 (EU Regulation 661/2009). Two flavours:
- Direct TPMS: a battery-powered sensor inside each wheel transmits pressure (and sometimes temperature) to the car's ECU. This is what most modern vehicles use. The sensor lives inside the tyre, usually built into the valve stem.
- Indirect TPMS: no in-wheel sensors — the ABS wheel-speed signals are compared, and a tyre going down is detected because it rotates faster. Older systems, simpler, but less precise.
The dashboard light comes on for one of four reasons: a tyre genuinely low, a sensor battery dead (typically 5–10 years), a sensor damaged during a previous tyre change, or the system needing a relearn after a tyre/wheel swap.
What I can do on the driveway
For direct TPMS systems (the vast majority of cars):
- Replace a dead or damaged sensor. I carry programmable sensors that cover most makes — Schrader EZ-Sensor, Alligator Sens.it, equivalents. They get programmed to your car's protocol on the van before fitting.
- Replace the sensor service kit (valve core, grommet, nut) on every tyre change. That's the part that usually fails first, before the sensor itself.
- Relearn the new sensor IDs to the car so the dash light goes out. Most makes use one of three relearn paths:
- Auto-relearn (BMW, many VW Group, many Ford): drive for 10–20 minutes at over 25 mph and the system picks up the new IDs.
- Manual/stationary relearn (some GM, Stellantis, Toyota): button sequence or magnet activation, supported by my TPMS tool.
- OBD relearn (Hyundai/Kia post-2018, some premium European): the new IDs are written to the ECU through the OBD port.
For indirect TPMS (no sensors in the wheels): nothing to replace — just a system reset through the dash menu after the new tyres are fitted. I do this as part of the job.
Where the honest limits sit
A handful of cars need a manufacturer-specific OBD relearn with the dealer's diagnostic tool. The ones I see most often:
- Some recent Tesla models — sensor IDs are paired through the central screen, but firmware versions vary and a re-pair occasionally fails.
- A small number of very-recent Stellantis (Peugeot/Citroën/DS) and Alfa models where the relearn protocol changes mid-model-year.
- Heavy or specialist vehicles using a proprietary TPMS (some motorhome chassis, EV-specific systems, fleet telematics setups).
Where this hits, I'll either get the sensor fitted and the tyre fitted properly (so you're safe and legal) and you finish the relearn at the dealer, or — more often — I'll say up front "this one's a dealer job, not a mobile job" and we don't waste your time.
The vehicles I don't cover at all are motorbikes, HGVs/lorries and agricultural — that's true for tyres as a whole, not just TPMS.
What it costs
Sensor itself plus fitting plus relearn is a call-for-quote job — the variables are sensor make, whether one or four need doing, and whether your car needs the OBD relearn path. I won't put a "from £X" headline here because it'd be wrong half the time. Ring me and I'll quote on the spot for your specific car.
What to do when the light comes on
- Check pressures cold. Most TPMS warnings are a genuinely low tyre, not a fault. The placard with correct pressures is inside the driver's door jamb on most cars.
- If pressures are correct, drive for 20 minutes. Some systems take a while to update — the light may clear on its own.
- If it's still on, ring me. I can come to you with a TPMS reader, diagnose which sensor (or which fault) is causing it, and quote on the fix.
If your tyre is genuinely flat, don't wait — that's a mobile puncture repair or a same-day tyre fit job, not a TPMS-only job.
Frequently Asked Questions
How long does a TPMS sensor last?
Battery life is typically 5–10 years depending on usage. They're sealed units — when the battery fails, the sensor is replaced as one piece (battery isn't separately serviceable).
Can I drive with the TPMS light on?
Legally yes (the warning is informational, not an MOT failure on its own), but it disables the system that warns you about a tyre going down — so you'll be running blind until it's fixed. It's worth sorting at the next opportunity, not ignoring.
Do new tyres need new sensors?
Not unless the existing ones are dead or damaged. What does always get replaced on a tyre change is the sensor service kit — the rubber grommet, nut and valve core that sit between the sensor and the wheel. They're consumables. Reusing them risks slow leaks.
Can you reset TPMS without a tool?
For some makes yes (auto-relearn or stationary button sequence in the car's menu). For others you need a TPMS tool, an OBD device, or both. I carry the kit needed for the brands listed above — it's part of the standard fit.
What if my car is too new to be in your tool's database?
Honest answer: I'll check the year/make/model before I commit, and if my tool doesn't cover it yet I'll tell you. Most TPMS tool firmware updates monthly so coverage gaps close quickly, but I'd rather flag it than guess.
