Tyre pressure warning
The light that sends most people to this page
Tyre pressure warning light on? TPMS servicing at your door
Your tyre pressure monitoring system, or TPMS, warns you when a tyre loses pressure. When the light stays on or flashes, a tyre may be low or a sensor may have failed. We check it and replace sensors at your home or workplace, Monday to Friday.

The warning light
What does the tyre pressure warning light mean?
On most cars the light behaves in one of two ways, and they mean different things.
Steady
Light on and steady
One or more tyres is below the pressure it should be. Check and inflate all four to the figures in your handbook or door frame. If one keeps losing air, you may have a slow puncture, so we treat a steady light as a possible puncture and check the tyre first.
Flashing, then on
Light flashes, then stays on
This usually points to a fault in the system itself, often a sensor that has failed or whose battery has run flat. Inflating the tyres will not clear it, so we treat it as a sensor fault.
A TPMS fault can fail your MOT
If your car was first used on or after 1 January 2012 and has TPMS, a warning light showing a fault with the system is an MOT failure. Getting it checked before the test saves a fail and a retest.
How it works
How a TPMS visit works
Most tyre pressure warning lights come down to a tyre that is losing air or a sensor that has stopped working. The fitter checks them in that order, so you only pay for what your car needs.
1
Tell us what the light does
Send your reg and postcode and tell us if the light is steady or flashing. That tells the fitter where to start.
2
Pressures and tyres first
All four tyres are set to your car’s figures and checked for a slow puncture. If a tyre needs repairing, we price it before any work.
3
The sensors are checked
If the light still shows a fault, the fitter checks each sensor to find the one that has failed.
4
Tyre pressure sensor replacement
A failed sensor is replaced and coded to your car, and we check the warning light has gone out before we leave.
The TPMS check is free when we are already with you for another job, such as new tyres or a puncture repair. We also measure the tread depth on every tyre while we are there.
What servicing involves
TPMS sensors: what we check and replace
Direct TPMS
Most cars have a small tyre pressure sensor inside each wheel, fixed to the valve. Each one reads the pressure and sends it to the car.
Indirect TPMS
Some cars work out pressure from the wheel speed sensors instead, with no sensors in the wheels.
Seals, valves and batteries
The seals and valve core on a sensor wear over time. The battery inside is sealed and usually lasts around 5 to 7 years, then the whole sensor is replaced and coded to the car.
When to book a TPMS check
- The light flashes when you start the car, then stays on
- The light stays on although all four tyres are at the right pressure
- The light came on after new tyres or wheels were fitted
- Your MOT is coming up and the light is on
- Your car is more than five years old and has never had a sensor replaced

Why is my tyre pressure light on when my tyres are fine?
A steady light can mean a tyre is losing air slowly, so we check for a puncture first. A flashing light usually means a fault in the system itself, most likely a sensor. A TPMS check tells you which, and it is free when we are already with you for another job.
Can I drive with the TPMS light on?
Check your pressures as soon as you safely can. If they are right and the light stays on, the system has a fault. The car is usually fine to drive carefully, but get it checked, because you will not be warned if a tyre does go down.
Will a tyre pressure warning light fail my MOT?
It can. If your car was first used on or after 1 January 2012 and has TPMS, a warning light showing a fault with the system is an MOT failure. Book a check before the test to avoid a fail and a retest.
How long do TPMS sensors last?
The battery in a sensor usually lasts around 5 to 7 years. It is sealed inside, so when it runs out the whole sensor is replaced.
Why is my tyre pressure light on after new tyres?
A sensor may have been damaged when the tyre was changed, a valve seal may be leaking, or the car may need to relearn the sensors. A TPMS check finds which.
How do I reset the tyre pressure warning light?
Set every tyre to the pressure shown in your handbook or on the sticker inside the driver’s door or fuel flap. Many cars then reset the light through the settings menu or a button, as the handbook explains. If the light comes back or keeps flashing, the system has a fault and needs checking.
Can you replace a tyre pressure sensor at home?
Yes. We supply the sensor, fit it and code it to your car at your home or workplace. It costs £90 including VAT per sensor when we are already with you for another job. If we come out just for the sensor, a travel charge is added and we confirm it when you book.
Is the TPMS check free?
Yes, when we are already with you for another job, such as fitting tyres or repairing a puncture. If a sensor needs replacing, it costs £90 including VAT, supplied, fitted and coded to your car. If you need us to come out just for the warning light, call 0330 043 4147 and we will confirm the cost when you book.
How do I pay?
By cash or card, and card payments can be contactless. You pay when the job is done.
