C4S speedo

[Tiptronic2]

I wondered if anyone here with a C4S has experienced a difference in apparent speed between the digital speed display and the analogue display. Mine always reads about 10% faster on the digital display for some reason - not sure sure which is right and don't want to risk going 10% slower than necessary!

Just to make you feel better my digital speedo is also out by a fair way! The analogue one is almost bang on the money compared to a GPS but the digital one, for me, displays outside air temperature only now []

that's a good idea - I hadn't thought of that I will try the GPS.

My analogue speedo is pretty accurate compared with a GPS, but starts to over-read by one or two mph over 80 mph. (On de-restricted autobahns only, of course).
