HAVE A Renault SCENIC Speedo is KPH CAN IT BE CHANGE TO MPH

If your Renault Scenic is changing the display settings back to the default settings when you start the vehicle, it is possible that there is an issue with the vehicle's settings or its onboard computer. It is also possible that the vehicle's software has become corrupted or that there is a problem with the display itself. I recommend trying the following steps to resolve the issue:

1. Disconnect the vehicle's battery for several minutes, then reconnect it and start the vehicle. This can sometimes reset the vehicle's onboard computer and fix any issues with the settings or software.
2. If the problem persists, try updating the vehicle's software by visiting a Renault dealership or service center.
3. If the problem still occurs after updating the software, you may need to have the vehicle's onboard computer and display system checked by a trained technician.

It is important to have this issue addressed, as it could be a sign of a more serious problem with the vehicle's electronic systems. I recommend contacting a Renault dealership or service center for further assistance.

check its engine oil first......also check in morning there is any pollution.....if it have then replace its ring set and piston..

Go to the trip computer settings.

You will need a clip tool or dealer can change language will take 5 minutes

yes

Go on line and find a used Spider speedo USA or UK and change the whole assembly. It's easier to change than taking apart the speedo. Also there are some new ones on the net too.

You probably have a broken speedometer cable. Was the needle wagging back and forth and making strange noises periodically before it quit working?

new unit complete

It could be the sender unit from the transmission.
Or it could be that the head unit (the speedo its self) has a problem.

Change the sender unit first.

is the car petrol ? if so have you changed the plugs
