McLaren Tyre Pressure Monitoring System Replacement in Bristol | Hometyre Mobile TPMS Experts

A legal requirement for passenger vehicles post 2012, the Tyre Pressure Monitoring System (TPMS) can be found on pretty much all vehicles in two different forms; Direct and Indirect.

Direct systems have the sensors in the wheels so can display the pressures of each wheel to the main display in the cabin.

Indirect systems monitor the pressures using the ABS (Anti-lock Braking System) sensor housed in the wheel hub. These sensors then relay the information to the car's central computer. One of the big downsides to these indirect sensors is that they can't display the individual pressures but instead only warn the driver if there is a pressure issue. The big upside is that they are cheap so can be found more commonly on economy cars whereas the direct sensors are found on more luxurious and high-performance cars.

Speaking of high-performance cars, we recently went out to this McLaren 570S in Long Ashton, Bristol Bristol that had an error appear on the dashboard indicating an error with one of the sensors. If the TPMS light is static then there is a pressure loss. However, if the sensor is flashing then there is an issue with the sensor itself.

After arriving at the customer's work location, we scanned the units to see what the probably was. Almost immediately, the error presented itself; Low Battery! Being only four years old, this was a bit worrying but makes sense if the vehicle is not driven often.

Carefully taking each wheel off, the tyre was removed and the old TMPS unit taken out. The new McLaren specific black unit was programmed with the old sensors data (so all the car would see is that the units now had 100% battery!), the tyre checked, reinstalled, inflated to the correct pressure and finally balanced. Before the customer could be on the road again, the TPMS system was calibrated from inside of the car.

On a side note, one of the more recent technological advancements is the introduction of the 'Cyber' tyre from Pirelli. Using sensor attached to the back of the tyre (inside of the wheel) it can send the tyre pressures, temperatures, and wear rates to a display in the cabin. Currently found on the McLaren Artura, this system can be retrofitted to other vehicles with the installation of the in-cabin display much like any TPMS system.
