They must show speed equal or greater then the actual - to be on the safe side. Normaly it's about 10% off so the faster you drive the more the difference is.

My digital speedo and my needle are pretty much the same


When I check my Micro RoadPilot (GPS Speedo) it reads about 3 - 4 mph higher than my cars speedo.  I guess this is a good thing as it gives you a bit of tollerance when going through speed traps etc.

I'll bet you drove an extra mile for your mileage to be that neat for the photo  :laugh:
How come your speedo needle is blue in the pictures?

Sorry to drag up an old thread.
Just wanted to check what would be the average over read of the speedo?
Came round a corner today and was faced by a camera van in a 30.
Don't think I was speeding but when I looked the digital mfd said 48km/hr, which I know is around 30 on the speedo.
What would be my likely true speed? 26, 27?

Thanks

How do you get the speed up in the MFD as I cannot seem to figure it out, I have read the manaul, but have still been unable to turn it on. Any help would be great, thanks.

kmh should be on the mfd at all times by deafult but you can change it to mph with vag.com

Am sure on my mark 5 with 30 on the speedo, it says 26/7 on the climate control when you get the speed up.

Ah well, I'll know in 2 weeks time.
