What's up guys? I am new to this forum and have a problem. It seems the Speedometer is constantly inaccurate. 10 miles per hour to be exact. When it says i am going 65 on my speedometer i am actually going 55. What could be causing this problem. Any info would be greatly appreciated.

the transmission is also original. Does a 81 320i have a sensor in it? All i see is the speedometer cable coming from the transmission. The cables are fine since I do get speeds on my speedometer.

Mmm maybe I can swap out my gauge with a spare that i have and test it from there. If anyone else has any ideas please post on this topic.

Thanks,
