That little yellow horseshoe on your dashboard. Most drivers either freeze up or flat out ignore it for weeks. Neither works out well, honestly.
Your TPMS warning light is not random. The car is telling you something is off whether that is tyre pressure, a dodgy sensor or occasionally both at the same time. Deal with it early and you are fine. Leave it too long and you are looking at blowouts, patchy tyre wear, or a nasty MOT surprise you really did not need.
Worth spending five minutes on before you ring anyone.
What Is the TPMS Warning Light and Why Should You Care?
Tyre Pressure Monitoring System (TPMS) is the term used for the system. All cars sold in the UK from 2014 have been fitted (unless exempted).
Small sensors sit inside your wheels and track pressure as you drive. The moment pressure drops past a certain point, the light comes on. Simple enough in theory. The annoying part? The light does not tell you which tyre. It does not tell you why. Just on.
Two Systems, Two Very Different Setups
- Direct TPMS puts a physical sensor inside each tyre. More precise, more common in newer cars.
- Indirect TPMS works through the ABS, comparing how fast each wheel spins rather than reading pressure directly. No sensors inside the tyres at all.
These two systems behave differently when something goes wrong. Worth knowing which one your car uses before you assume anything. Check the handbook, or ask a technician when you next book a mobile tyre fitting appointment.
Before You Call a Fitter, Do These Three Things
Booking someone out before checking the basics yourself is a bit like calling a plumber before checking if the tap is turned on. Give it five minutes first.
Step 1: Check the Tyre Pressure Properly
Drive to the closest petrol station and use the air machine. Do not just look at one tyre but inspect all four. Normally the correct pressure will be listed on a small sticker inside the driver’s door frame or in the car’s handbook.
If every tyre is at the right pressure and the light is still on the fault is in the sensor not the tyre. Drivers who book a TPMS Sensor Check Richmond upon Thames appointment often find out the pressure was perfectly fine. A reset is all it took.
Step 2: Walk Around and Actually Look at the Tyres
It sounds obvious. Most people skip it. Inspect car for nails, screws, bits of glass, etc. by walking around the car. Also check whether any tyre looks visibly lower than the others when the car is sitting still.
If you find something, a puncture repair service can come to you wherever you are. No need to limp to a garage on a damaged tyre. For anything more urgent, an emergency tyre callout gets someone to you fast, roadside or otherwise.
Step 3: Is the Light Solid or Flashing?
This one matter more than most people thinks.
- Solid light = pressure issue in one or more tyres
- Flashing light = sensor or system fault, not necessarily a pressure problem
A flashing TPMS light is not automatically dangerous, but it does need attention. TPMS Diagnostics Hammersmith and nearby areas have mobile technicians who carry scanning equipment and can read the fault codes on-site, in your driveway if needed.
When Should You Actually Call a Mobile Fitter?
After the checks above, you will have a better read on the situation. Here is when calling in a mobile technician makes real sense:
- Pressure keeps dropping back down after you inflate the tyre
- The light stays on even with all four tyres correctly inflated
- There is visible damage or something embedded in the tread
- The sensor needs resetting after a recent tyre change
- Driving to a garage would put you or the tyre at risk
Mobile TPMS Service Barnet runs same-day in north London. Down south, TPMS Repair Bromley covers cars, vans, and SUVs with vans that carry the tools and stock to sort it on the spot.
One more thing worth knowing: if you are already getting a mobile callout, pair it with a mobile wheel balancing check at the same time. Saves booking twice, and your tyres will thank you for it.

TPMS Light Came Back on After a Tyre Change? Here Is Why
These trips people up constantly. New tyre fitted, pressure correct, everything should be fine. Then the TPMS light comes back on before they have even got home.
When a tyre is removed and put back the sensor inside loses its pairing with the car’s system. It needs to be reset and re-recognised. Without that step, the light just keeps coming back on regardless of pressure.
A TPMS Reset Service Westminster or a nearby mobile reset service takes a matter of minutes with the right equipment. The thing is, not every fitter includes this automatically. When you book a mobile tyre fitting or home tyre fitting, ask specifically whether the sensor reset is part of the job.
The same rule applies with seasonal tyre changes. Running all season tyres year-round avoids this entirely, but if you swap between winter and summer sets, a reset needs to happen each time the tyres come off.

Questions UK Drivers Ask About TPMS
Who should reset a TPMS sensor after a tyre change?
A mobile technician with dedicated TPMS reset tools, not just any garage with a generic scanner.
What does a flashing TPMS light mean compared to a solid one?
Solid means pressure is low in one or more tyres. Flashing points to a sensor or system fault rather than pressure.
When does a TPMS sensor need replacing rather than just resetting?
If the sensor is dead, it is physically cracked or damaged or it continues to fail after reset.
Where can I get a TPMS check without visiting a garage in London?
TPMS Sensor Repair London through a mobile service means the technician comes to you, home, work or roadside.
Why does the TPMS light trigger more in winter than in summer?
Cold air reduces pressure inside the tyre naturally. That drop alone is often enough to cross the sensor threshold.
Simple Habits That Keep Your TPMS in Good Shape
- Check tyre pressure manually every two to four weeks, regardless of what the dashboard says
- Replace TPMS sensors alongside new tyres on any vehicle past the six-year mark
- After an emergency tyre replacement, confirm the sensor has been reset before pulling away
- Performance tyres and all season tyres sometimes need specific sensor calibration so mention your tyre type when you book
- Keep a brief service record for your sensors, useful if a TPMS fault gets flagged during an MOT
- Driving a van or 4×4? Ask specifically about compatibility when booking as 4×4 tyres and commercial vehicles sometimes use different sensor types.
The TPMS Light Is a Warning Not a Worst-Case Scenario
Nine times out of ten it is something straightforward. A pressure drop. A sensor that needs resetting. A battery that ran out quietly after years of service.
Check the pressure first. Look at the tyres. Then you will know whether you need help or just a quick reset at the petrol station. Most TPMS issues get resolved at the roadside or at your home in under half an hour when a properly equipped mobile technician handles it.

FAQs
How much does TPMS sensor replacement cost in London?
It will be dependent on the type of car and the type of sensor. Never agree to any price without proof. Tyretick quotes upfront with no surprise charges afterwards.
The TPMS light came back on straight after a tyre fitting. Is something wrong?
Almost certainly not with the tyre. The sensor just needs recalibrating. This is why it is worth confirming the reset is included when booking a home tyre fitting or a puncture repair service.
Do electric cars need TPMS sensor checks as well?
Yes and arguably more so. EV tyres carry more weight and wear faster than standard tyres. An accurate TPMS reading matters more, not less, on an electric vehicle.
Does TPMS cover vans and commercial vehicles?
It does. Vans sold in the UK have TPMS fitted as standard. Van tyre fitting services cover sensor checks and replacements too, and mobile vans carry van-specific sensor stock.
