My Daughters Mini speedometer is off by 7 MPH. It reads 67 when she is doing 60. The car has the factory 205/45 17 Perelli tires and wheels. Is there a way to recalibrate the speedometer?
Speedometer calibration on 2008 Mini Cooper S
I would first inspect the vehicle speed sensor, because if that is wearing out then the mph will be off. Ever get any check engine lights on, if so, then you may have a Vehicle Speeds Sensor code. Get this issue resolved and if that is all with in spec, then have a shop with a Mini factory scanner check the accuracy of the Speedo, it may be failing, because I have not really heard of a Speed losing its calibration, unless there was some glitch that told the computer system that all of a sudden you have different size tires, that is possible, but it would be unusual.
I have a 2008 Mini Cooper S and the speedo is off the same as yours. I did some research into the issue and found out that BMW set it that way on purpose. I don't know why but when I asked my Mini dealer to fix it they said they have the ability to but they are not allowed to fix it. This made no sense to me. So I know this question was asked three years ago but I noticed that the answer was to go through a lot of checks and none of them will do any good as that is the way they are from the factory.
