Speedo reading low
I’ve searched in both tech and general and can’t seem to find any truly relevant threads, so thought I’d ask. The speedo in my 2000 Base coupe, m6, is reading about 8 kph, or 5 mph, low as compared to 2 different gps’s. Tire size is original, no erratic speedo operation, it’s off equally in mph or kph. Any suggestions as to where I could start looking?
