Mobile TPMS Sensor Replacement & Reset - Direct Sensors at Your Door
TPMS warning light won't go out, even after you've topped the pressures up? Nine times out of ten that's a dead sensor battery — they last 5–7 years and they aren't user-replaceable. I'm Simon, owner-operator at Breakdown Man, based in WN5 Wigan, covering the North West. I bring programmable replacement sensors and the diagnostic tool to the driveway, fit them, reset the system, and you're done. Quote on the call, no call-out fee. 07549 676 220.
What TPMS Does — and Why It Eventually Fails
TPMS — Tyre Pressure Monitoring System — has been a UK MOT requirement on passenger cars first registered from 1 January 2012, and a mandatory fit on all new passenger cars sold in Europe since November 2014. The dashboard warning light is not optional — a TPMS that isn't working will fail the MOT.
Two flavours run in the UK fleet:
- Direct TPMS (most cars from ~2014 onwards) uses a small battery-powered sensor inside each wheel, transmitting actual pressure to the car. Sensors last 5–7 years on average. The battery is sealed in — when it dies, you replace the whole sensor.
- Indirect TPMS uses the ABS wheel-speed sensors to detect an under-inflated tyre (it rolls slightly faster than the others). No sensors to fail — the system just needs a recalibration after pressures are corrected or wheels are swapped.
Simon will tell you which one your car has when you ring with the reg, and price the job accordingly.
How a Mobile TPMS Job Works
- Ring with the reg. Simon checks the TPMS protocol your car uses (direct vs indirect, and which manufacturer ID).
- Quote on the call. Sensor cost varies by vehicle. He prices the full job — sensor(s), service kit, programming and reset — up front. No callout fee.
- On site, diagnostic first. The TPMS tool reads every sensor: ID, signal, battery health, last pressure. That tells you exactly which sensor(s) have failed and saves replacing healthy ones.
- Payment taken in advance. Once you've okayed the price, payment's settled up front before any work starts — bank transfer or cash. Nothing to pay afterwards.
- Wheel off, tyre off the rim. Standard mobile fitting procedure — the only way to safely change a TPMS sensor is to remove the tyre from the rim.
- Sensor swapped, service kit fitted. Old sensor out, new programmable sensor in, fresh rubber grommet/valve core/cap.
- Sensor configured. Either programmed with a fresh ID (and the car learns it on the next drive) or cloned to copy the failed sensor's ID (the car never knows).
- Tyre back on, balanced, refitted. Torqued to spec, warning light reset on the diagnostic tool.
- Test drive optional. On vehicles that need a relearn drive cycle, a short drive completes the process — Simon will tell you if your car needs it.
Single-sensor replacement is typically 30–40 minutes once Simon's on site. A full set of four is closer to 90 minutes.

FAQs — TPMS Sensor Replacement
What is TPMS and why is the warning light on?
TPMS stands for Tyre Pressure Monitoring System. Since November 2014 all new passenger cars sold in the UK have to be fitted with one; from 2015 it became an MOT-fail item on those cars. The warning light on the dash means one of two things: a tyre is genuinely losing pressure, or one of the sensors has failed (typically a dead internal battery on a direct-TPMS sensor — sensors last 5–7 years on average and they aren't user-replaceable). I can check pressures on site and read the sensors with a diagnostic tool to tell you which it is.
Direct TPMS vs indirect TPMS — which do I have?
Direct TPMS has a battery-powered sensor inside each wheel transmitting actual pressure to the car. Indirect TPMS uses the ABS wheel-speed sensors to detect a smaller wheel circumference (an under-inflated tyre rolls slightly faster). Most UK cars from ~2014 onwards use direct. If your car has direct TPMS and a sensor's failed, the only fix is a replacement sensor. Indirect TPMS doesn't have sensors to replace — if the warning light is on, the system just needs a recalibration after pressures are corrected.
Do I have to replace all four sensors at the same time?
No — single sensor replacement is fine. That said: if one sensor's battery has died at age 5–7, the other three are usually within 6–12 months of doing the same. Some customers prefer to swap all four at once to avoid another callout next year. I'll tell you the actual age of each sensor on the diagnostic before you decide.
What's a TPMS service kit and do I need one with every tyre change?
The service kit is the rubber grommet, valve core and dust cap that seal the sensor stem to the rim. Industry best practice — and the position of all major sensor manufacturers — is to renew the service kit every time the tyre comes off the rim. The grommet compresses; the core can corrode; once the seal goes, the tyre slowly loses pressure and the warning light comes back. I fit a fresh service kit with every tyre change as standard.
Can you reset the warning light without replacing anything?
Sometimes. If the pressures are simply low (slow leak, cold weather drop), the light clears once they're brought back to spec and the car relearns. If the sensors are healthy but the IDs aren't recognised after a wheel swap (winter wheels, for example), a relearn with the diagnostic tool wakes them up. If a sensor's actually failed, there is no reset that fixes it — replacement is the only honest answer.
Will replacement sensors work with my car? I've heard about cloning.
Yes. I use programmable sensors that can be configured to match your vehicle's TPMS protocol. There are two options: program-new (the sensor gets a fresh ID, the car learns it on the next drive) or clone (the sensor copies the ID of the failed one, the car never knows it's a different sensor). Both work; some vehicles prefer one approach over the other and I'll tell you which on the day.
Can you do TPMS at the same time as a tyre fitting or puncture repair?
Yes — and ideally yes. Every TPMS-equipped tyre that comes off the rim should get a fresh service kit and have the sensor inspected. Combining the jobs into one visit is faster and cheaper than two callouts.
What does a TPMS sensor replacement cost?
Quote on the call. Sensor cost varies a fair bit by vehicle — premium German cars often use higher-spec sensors than mainstream Japanese ones. Service-kit replacement is a small per-wheel add-on. Ring with the reg or make/model and I'll tell you the lot up front.
Do you do motorbike or HGV TPMS?
No — cars, vans, 4x4s, caravans, motorhomes and EVs/hybrids only. Motorbike, HGV and tractor TPMS systems use different protocols and tooling.
