996 C2 2000 - Difference b/n Analog and Digital Speedo Readings

[Y2K911]

My analog and digital speedometer readings always differ: At 60km/hr, the difference is 3 km/hr and at 150 km/hr, the difference is up to 10 km/hr.

The analog reading is always higher than the digital reading.

Of course, I have no idea which one, ie, digital or analog, is the most accurate reading! ... and not about to ask an RCMP officer to check the accuracy of my speedometers at 150 km/hr, either.

Have any of you encountered the same speedo anomaly? Merci!

Very common in Porsche. Best way to check is with a GPS (Garmin).

It has a speedometer? Wow! I'm too busy having fun to notice that thing..... :D

I rarely use the analog speedo. Mostly the digital. In the 2006 Boxster it shows abour 2-3 MPH faster than actual (normal highway speeds). In the 1997 993 Turbo the digital is dead accurate.

Thanks guys! I get from this that the digital reading is likely more accurate than the analog one. I also default to digital reading most of the time but it is nice to still have the analog one for tradition's sake.
