Modifying your speedometer?

When importing a car to the UK from another country, it is often necessary to change the speedometer from kilometers per hour (km/h) to miles per hour (mph). This is because the UK uses mph as its standard unit of measurement for speed, while many other countries use km/h. If your car is under 10 years old at the point of import, we will need your speedometer to read in mp/h.

Why do you need to convert your speedometer?

In the UK, all speed limits and road signs use miles per hour (mph) as the unit of measurement. Therefore, if your car is being driven on UK roads must have a speedometer that is capable of displaying speed in mph. This is especially important for imported cars, which may have a speedometer that displays speed in kilometers per hour (km/h) by default, as this is the standard unit of measurement in many other countries.

If a car’s speedometer is not capable of displaying speed in mph, it can be difficult for the driver to accurately gauge their speed and comply with speed limits, which can be a safety hazard on the road.

Therefore, it is necessary to convert the speedometer on an imported car from km/h to mph when under 10 years old, and recommended for cars over 10 years old, to ensure that the car is suitable to drive on UK roads and that the driver can safely and accurately monitor their speed.

Frequently asked Questions

What is a speedometer fascia?

A speedometer fascia, also known as a speedometer gauge cluster or instrument cluster, is a component found on the dashboard of a car. It is a vital part of a car’s instrumentation and provides the driver with important information about the car’s speed, engine RPM (revolutions per minute), fuel level, engine temperature, and other critical indicators.

The speedometer itself is the main gauge that displays the car’s current speed, usually in miles per hour (mph) or kilometres per hour (km/h), depending on the country’s standard. It allows the driver to monitor their speed and stay within legal speed limits, promoting safe driving.

The fascia, in this context, refers to the housing or casing that surrounds the various gauges and indicators in the instrument cluster. It provides a unified and organized appearance to the dashboard and helps protect the delicate electronic components inside.

In modern cars, the speedometer fascia may be a digital display, which can show not only the speed but also other information in a graphical or numerical format. Older cars often have analogue speedometers with physical needles indicating the speed.

The design and layout of the speedometer fascia can vary significantly between different car models and manufacturers. Some may have a simple and minimalist design, while others may include additional features like a tachometer (shows engine RPM), odometer (displays total distance travelled), trip meters, fuel gauge, temperature gauge, and warning lights for various car systems.

Overall, the speedometer fascia is an essential component in a car’s dashboard that allows the driver to stay informed about the car’s performance and critical functions while driving.

What is the process for converting an analogue speedometer?

Converting an analogue speedometer from kilometres per hour (km/h) to miles per hour (mph) typically involves replacing the speedometer gauge face or dial with one that displays the speed in mph.

We find the correct replacement based on your car model. These vary and finding  the correct one is quite important.

Then to access the speedometer, we need to remove the dashboard panel. This process varies depending on the car, generally, it involves removing screws, clips, and possibly other parts that secure the dashboard panel in place.

It is something that we wouldn’t recommend you try yourself as the panels can be very tricky to put back where they were.

Then we carefully remove the current speedometer dial from the gauge cluster, and then we take the new mph speedometer dial and securely attach it to the gauge cluster in the same manner the old dial was connected. Sometimes there are other steps here depending on the car as some fascia’s are glued in!

Once everything is back together we check it is calibrated and that it looks correct once the speedometer housing is put back together.

You can do it yourself to save money but it is a really tricky job that we would not recommend.
