Sometimes It Is the Seal, Not the Sensor
Three completely different things get called a failed TPMS sensor, and only one of them actually is one.
The first is the service kit. That is the rubber seal, the valve core, the retaining nut and the cap. They are consumable parts. They perish with age, they corrode, and they get damaged during a tyre change. Replacing a kit costs a fraction of replacing a tyre pressure sensor.
The second is the stem. On a lot of sensors the stem can be swapped on its own while the sensor body carries on working perfectly well.
The third is the sensor itself. The battery is sealed inside, so once it is flat the whole unit gets replaced. Same if the body has been cracked by a pothole.
Here is the pattern I see more than any other: a light that appears within a week of somebody else fitting new tyres is almost never a dead sensor. It is a seal that was not replaced, a stem snapped on removal, or a sensor that never got re-learned.
So we read the sensors first. If yours are fine, we tell you they are fine. We do not guess, we diagnose.
Direct or Indirect: Not Every Car Has Sensors in the Wheels
Worth checking before anybody quotes you for four of anything.
Direct TPMS
Direct TPMS is what most people picture. A small battery-powered sensor sits inside each wheel, usually built into the valve stem, and sends a live pressure reading to the car.
Indirect TPMS
Indirect TPMS has no sensors in the wheels at all. It works off the ABS wheel speed sensors instead, spotting a soft tyre by the fact that it rotates slightly faster than the others. There is nothing in there to replace. Usually it just needs resetting after you inflate the tyres or have a tyre changed.
That distinction matters to your wallet. If your car uses indirect TPMS, nobody should be quoting you for sensors you do not have.
Establishing which system your vehicle runs is the first thing we do, and it takes a registration lookup rather than a callout.
What Actually Goes Wrong
The battery has reached the end of its life
Tyre pressure sensor batteries typically last around five to ten years, depending on mileage and climate. The battery is sealed into the unit and cannot be changed on its own, so the sensor gets replaced. A lot of the 2015 to 2018 cars still on the road round here are arriving at exactly that point now.
The light came on after new tyres were fitted
Very common, and rarely a coincidence. The usual causes are a perished seal that was not renewed with the tyre, a stem snapped while the old tyre was levered off, or a new sensor that was fitted but never re-learned to the car.
Pothole and kerb damage
Sensor bodies crack and stems bend. Pothole season runs roughly January to March here, and the kerbing that comes with tight city parking does its share too. More on that in our guide to pothole tyre damage.
Corrosion
Road salt goes down from November through March and it attacks alloy valve stems and the seat the seal sits against. A properly Scottish failure mode, and one reason service kits matter more up here than in a dry climate.
A seized metal valve cap
Those aftermarket metal caps look smart and then corrode onto an alloy stem. Force one off and the stem can snap, which turns a free job into a paid one. Keep the plastic caps the sensor came with. Honestly, that one tip has saved more sensors than anything else I could tell you.
Tyre sealant
Plenty of new cars ship with a sealant canister instead of a spare wheel. Some aftermarket sealants are ammonia-based and can wreck a sensor from the inside. Check the label before you squeeze it in.
One line on the light itself: a solid warning light usually means genuinely low pressure, while a light that flashes for around a minute and then stays on usually means a system or sensor fault. We have written that up properly in what to do when your TPMS warning light comes on, so read that first if you are still working out which one you have.
In a Glasgow Cold Snap, Most TPMS Lights Are Not Faults
1 PSI drop for every 5°C
Tyre pressure falls by roughly 1 PSI for every 5 degrees Celsius the temperature drops. So a mild week followed by a cold morning will switch warning lights on across the whole city inside about 48 hours.
“The phone tells me winter has arrived before the forecast does.”
Before you book anything, check your pressures against the placard on the driver’s door pillar or inside the fuel filler flap, set them cold, and reset the system. If the light goes out and stays out, nothing has failed and you owe nobody anything.
If it comes back within a few days, that is different. That is a leak or a sensor, and it is worth a look. Our guide on one tyre that keeps losing pressure covers where to start.
A New Sensor Has to Be Taught to Your Car
Fitting a tyre pressure sensor is only half the job. The car has to accept it.
A new sensor is programmed to your vehicle first. On many cars a programmable sensor can be cloned to the original sensor’s ID, which means the car recognises it straight away without any further work.
Then comes the re-learn. Some vehicles pick the new sensor up automatically over a short drive. Some need an OBD re-learn through the diagnostic port. Some use a manual procedure at each wheel.
What that means for you: on an auto-learn car the light may not clear the moment we drive away. It can take a few miles at road speed. We will tell you before we leave which sort your car is, so you are not sitting there at teatime wondering why the light is still on.
OE or aftermarket?
Both, and the honest answer depends on the car. Programmable aftermarket sensors match the function of the original on a lot of vehicles for meaningfully less money. On certain marques the manufacturer’s own sensor is the cleaner option and we will say so rather than talk you into the cheaper part.
What Happens When We Come Out
Registration First
We take your registration at quote stage, so the correct sensor type is identified before the van leaves.
Read Every Sensor
Every sensor is read for its ID and battery status, not just the one the car is complaining about.
Cold Pressure Check
Pressures are checked and recorded cold where possible.
Fault Identified
The actual fault is identified and explained to you before a single part is fitted.
Wheel Off, Bead Broken
The wheel comes off and the bead is broken, because the sensor lives inside the wheel.
The Right Part Fitted
The service kit, the stem or the sensor is replaced, whichever the fault turned out to be.
Programmed and Re-learned
The new sensor is programmed and re-learned.
Wheel Back On, Torqued
The wheel goes back on, torqued properly and rebalanced where it needs it.
Light Off, Or Drive Cycle Explained
We confirm the light is off, or explain the drive cycle if the car needs one.
Zack does most of this work and he is the name that keeps appearing in our reviews, which tells you something.
One honest note: some faults only become fully visible once the tyre is off the rim. If what we find changes the price, you hear it then, not on the invoice.
TPMS Sensor Replacement Cost in Glasgow
We do not publish a fixed price list, and I would rather tell you why than pretend otherwise. Every job here depends on what actually failed.
What is useful is the shape of it. Across the market a service kit is the cheapest outcome by some distance. A stem-only replacement sits in the middle. A complete tyre pressure sensor is more than either. And a main dealer sensor is typically the dearest route of all, with documented UK cases of over £100 per corner for a part that a programmable equivalent can replicate for considerably less. Those are market figures for context, not our prices.
What moves your number: how many corners are affected, whether a tyre is being fitted anyway, the sensor type your car takes, whether programming or an OBD re-learn is needed, and the time of day.
You get a quote before we travel, and the quoted price is what you pay.
If a tyre is being replaced or repaired anyway, the wheel is already off. Sorting the sensor or the service kit at the same time costs less than a separate visit.
Will a TPMS Fault Fail an MOT?
Yes, but only for certain vehicles, and the qualifier is the part most pages leave out.
A tyre pressure monitoring system malfunction indicator showing a fault is a major defect at MOT for vehicles first used on or after 1 January 2012. On a vehicle older than that, it is not a test item at all.
The two dates that get muddled elsewhere are simple enough once separated. Type approval required TPMS on new car models from November 2012, and every new car registered from November 2014 onwards had to have it. That is why you will see both years quoted, and why neither on its own is the whole answer.
The DVSA MOT inspection manual, section 5 covers wheels, tyres and fixings if you want the source.

Mobile TPMS Repair Across Glasgow and Nearby Towns
Driveway, work car park, roadside, multi-storey. If the car is there and the wheel can be taken off safely, we can do it there.
Searching for TPMS repair near me and getting a list of shops that shut at six is a familiar problem, and it is most of the reason we run the hours we do.
We also cover Paisley, East Kilbride, Hamilton, Rutherglen and Cambuslang, with the same service running further out in Edinburgh, Aberdeen, Dundee and Inverness.
Arrival times vary by where you are and what else is on. We give you a real window when you call, not a comfortable one. And if you are wondering whether there is anyone doing this near me on a Sunday, there is.
What Else We Do While We Are There
Mobile tyre fitting, puncture repair, wheel balancing and locking wheel nut removal are all part of the same visit if you need them. Drivers who work for a living can find how we handle vans, taxis and private hire on our fleet and business customers page.

TPMS Questions We Get Asked
How much does it cost to replace a TPMS sensor?
It depends on what failed. A service kit is the cheapest fix, a stem-only replacement sits in the middle, and a complete sensor is the most. Main dealer parts are typically dearest of all. We quote before we travel once we know your registration and which corners are affected.
Do I have to replace all four TPMS sensors at once?
No, and anyone insisting otherwise is guessing. If one battery is flat the other three are the same age, so replacing the set can make sense on an older car and saves repeat visits. But it is a recommendation, not a requirement, and you decide.
How long do TPMS sensors last?
Typically around five to ten years, depending on mileage, climate and how many tyre changes the sensor has been through. The battery is sealed inside the unit, so it cannot be replaced separately. Salt and repeated bead-breaking both shorten the life of the seal well before the battery gives up.
Will a TPMS fault fail an MOT?
For vehicles first used on or after 1 January 2012, yes. A malfunction indicator showing a fault is recorded as a major defect. On older vehicles the system is not a test item. If your test is booked, tell us the date and we will work to it.
Why did my TPMS light come on after I had new tyres fitted?
Usually because a consumable part was not renewed with the tyre. The rubber seal perishes and should be replaced every time, the stem can snap while the old tyre is levered off, and a sensor that was disturbed sometimes needs re-learning to the car afterwards. Rarely a dead sensor.
Can a TPMS sensor be repaired instead of replaced?
Partly. If the seal, valve core, nut or cap has failed, a service kit fixes it and the sensor stays. On many sensors a damaged stem can be swapped on its own. What cannot be repaired is a flat internal battery, because it is sealed inside the sensor body.
Do new sensors need programming, and how long until the light goes off?
Yes, every new sensor is programmed to your vehicle. After that the car has to re-learn it, either automatically over a short drive, through the OBD port, or with a manual procedure. On auto-learn cars the light can take a few miles at road speed to clear.
My car has no sensors in the wheels, so why do I have a TPMS light?
Because your car uses indirect TPMS. It reads wheel rotation speed from the ABS sensors and flags a tyre that is turning faster than the rest, which means it is soft. There is nothing in the wheel to replace. Inflate to the placard pressure and reset the system.
