Speedometer error?

[mlrwy]

Hi Guys!
Is there any way to calibrate/adjust the speedometer in a E39?

Haven't heard of one...probably one deep in the DME somewhere. I think you are stuck with the factory 3-4% overread. The OBC is much more accurate than the speedo...


Cheers,

Not sure if this applies...
