Thanks, you just answered another question for me. I wanted to put a little bit bigger tire on my MINI next year, and now I know what size to go with!I'll have to borrow my brother's scan gauge and try it out.
HA!! I usually drive 5 over the posted limit, and now I know why everyone has been running up behind me so quick!

Yepper, mine gives the same numbers. I just went to 195/60R15 tires and it corrected one MPH. I have the scan guage above my rev counter and it will allow you to adjust the mph read out up or down to get a true reading. I use that and don't put the speed in the window anymore.

Guess that is why I never get pulled over... I am actually going the damned speed limit.

All Mini's do that. I am sure there is some corporate logic behind it.

I do the five over thing too and thought the same thing until I learned it was the speedo.

They get in real trouble
if the error is the wrong way.... But when I was having OBC problems with gas mileage calculations, the SA at Mini of Mountain View gave me a copy of speedo error stuff. They can correct it but it's corporate policy to not do it if the error is relatively small, like less than 7 MPH or 10% whichever is smaller.

I agree - I really want the speedo to be accurate.

Mine reads in kilometers, so by the time I convert to MPH, then make the adjustment for the tires, and the % the speedo is off, I'm in a different speed zone:lol:
I think it is a Euro law that speedos read highut:

All German cars (BMW/MINI included) have a fast speedo by 5-10 mph. Corporate policy.

I'm not sure what that would be a law in Europe. I did not think any drivers over there even looked at the speedo. :lol:

Hey Jim......
Don't let opportunities go to waste. You can now use that big spedo face as a picture frame for you favorite horse. -
Whats even weirder is that diff GPS's will give you diff results. I just upgraded from a Garmin 1260 to a 1490. The 1260 had me about 1-2 MPH faster than the speedometer and the 1490 has me 2-3Mph

This is the same thing I have run into. You would think the GPS would be stone-cold accurate.

I noticed this when I bought my first Garmin, since mine is now "hard" mounted, I just look at the Garmin to check my speed....
Don't bother taking it to the dealer to have it corrected, unless it's wildly off, they won't touch it, and even if they do all they'll do is change the speedo head, the new one could be worse!
And even tho it's been written about many times, I still find it hard to believe that they can't/won't make it more accurate. None of my Audis, Porsches or VW's had this much speedo error, in fact my Audis have always been dead on. So I call BS excuse on BMW here......
Tim, my 1490T reads slightly different than my old 660, but only 1 mph - and it may even be less than that as sometimes it matches what the 660 used to say...IOW, the 660 used to read 70 at the MINIs indicated 73, the new one reads 70 at indicated 72, but sometimes it reads 70 at 73 too. -
