TPMS issues causing increasing number of MOT failures

TPMS issues causing increasing number of MOT failures 23rd April 2015

Late last year, it became a legal requirement for all new cars in Europe built after 2012 to be fitted with a Tyre Pressure Monitor System (TPMS), to check and inform drivers about any issues with regards to the pressure of their tyres. 

However, while the new legislation is fantastic for reducing the number of tyre blowouts and increasing safety by alerting drivers to issues, it is also now catching more people out and causing a rising number of automatic fails in MOTs. 

Tyre charity TyreSafe has said that with millions of cars in the UK now fitted with a TPMS system, the number failing their MOT because of a new rule that as of January 2015, any TPMS errors that show up cause an automatic failure, has been rising considerably. 

"Although TPMS technology has been around for decades, its inclusion in new model vehicles has only been mandated in Europe since 2012 and on all new cars since 2014. This led to a gradual introduction into the market over a period of years and with little or no fanfare to help educate motorists." noted Stuart Jackson, chairman of TyreSafe.

TPMS works through having a sensor attached to the valve of a tyre and a dash-mounted indicator to tell the driver of any errors detected in air pressure. It can be a good indicator for car owners of when they need new tyres fitted and it can also help to highlight low air pressure before it leads to problems such as accidents. 

However, TyreSafe said the biggest issue faced is that drivers have little knowledge about TPMS, how it works and how to spot problems, all of which adds up and causes failures. 

As a result, the charity is now spearheading a new campaign to raise awareness of TPMS and how not maintaining it can cause cars to fail their MOTs. 

To make sure your TPMS is working effectively, there are a number of things you will need to do. For one, regular services are recommended. Although the system is designed to last many years, things can happen, such as malfunctions and batteries in the sensor running it. Taking your car in for a TPMS service can help spot these issues before it comes to time for an MOT. 

In addition to this, it's also recommended that the valve cap and core components are changed whenever you have a new tyre fitted to the car. This helps to maintain the integrity of the system as a whole in the long run.
