My odometer (mileage ) don’t work any more, yet I do have spare instruments . I wonder if I source a new plastic cogs , is kph same as mph cogs if I have to source it somewhere (in case bmw don’t have them or at ridiculous price, of course I will try them before I go eBay )
I want to give this a go, as I don’t want to buy another instruments as they gone silly price also it may need services as well
