That tyre pressure warning light doesn't always mean a puncture. Learn what triggers your TPMS light and when to call a mobile tyre technician in Glasgow.
The Tyre Pressure Monitoring System (TPMS) warning light – the horseshoe-shaped symbol with an exclamation mark on your dashboard – is there to warn you when one or more tyres are significantly under-inflated. But there are several reasons this light can come on, and not all of them mean you have a puncture or are about to have one.
The most common reason is simply low tyre pressure, often caused by natural air loss over time, cold weather (air contracts in cold temperatures, reducing pressure), or a slow puncture. In Scotland's variable climate, a significant overnight temperature drop can trigger the TPMS warning without any actual puncture. In this case, inflating all four tyres to the manufacturer's recommended pressures and driving for a few minutes should extinguish the light.
If the light stays on after inflating the tyres, or if it flashes continuously, this indicates either a faulty or flat TPMS sensor battery or an error in the TPMS module. TPMS sensors have a battery life of 5 to 10 years, and when the battery fails, the sensor must be replaced. This is particularly common after fitting new tyres – the process of removing and fitting the tyre can damage an old sensor. All our technicians are trained to handle TPMS sensors carefully and can replace faulty sensors on-site.
