TPMS (Tyre Pressure Monitoring System)
TPMS (Tyre Pressure Monitoring System) is an electronic system linked to your vehicles on board computer to monitor air pressure in the tyres. It has been designed to reduce accidents, increase fuel economy and also prevent poor tyre wear, all a result of incorrect tyre pressures, There are 2 main systems, In-direct and direct. In-direct uses information from the ABS/ESC system but Direct uses information from a pressure sensor fitted inside the wheel. When the tyre drops below a set pressure, a warning light will appear on the dash. As of November 2014, all cars by law have to be fitted with a TPMS which is also part of the MOT. If your vehicle has a warning light on when presented for MOT, it will fail.
If your vehicle has a direct TPMS installed, (with a sensor in the wheel) it's best practise to have your valve serviced or replaced each time your tyre is repaired or a new tyre is fitted. This can be done without replacing the sensor itself.
A service kit costs from £6 including VAT per wheel, Snap in TPMS valve from £5.40 including VAT per wheel and a bolt in TPMS valve from £8.40 including VAT per wheel.
If your TPMS light appears on your dash, it’s most likely indicating a punctured tyre, but could also be lack of tyre pressure maintenance or even a failed sensor. Sensors have an average life of 5-7 years and then need to be replaced.
We can also supply, fit and program new sensors to your vehicle to avoid that big main dealer cost!
