Brand new to BMW

I just bought a new 2011 E90, came with 37 miles. I love the car but I hate that I don't know how fast I am going and that I'm getting extra miles on my odometer. I know it puts extra miles on because I run a one mile route, I drove to the half way marker and the odometer said it was 0.7 miles which i know is incorrect. Are there any fixes to have it show the correct speed and distance?

While a European car speedometer error of 2~5% high is common due to Euro laws prohibiting speedos indicating under the actual speed, the odometers are independant and generally spot on. Of the 5 Bimmers I've owned, 4 had accurate odometers and one actually under-read distance by about 1.5%.

You might want to test yours over a longer span, either with accurate highway mileposts or a GPS. And if you really are encountering a 40% error, raise the issue with your dealer.

I'm taking it in tomorrow, I've been reading that it was a "normal" thing and dealers wouldn't touch it. Last night i set my cruise control to 70 and drove thru a 60mph zone with a speed detector and it stated I was going 64. Was just wondering if any had the same problem or found a solution to it.

Search for this. Our speedo's read about 5% fast on purpose due to European regulations that do not allow cars to run faster than indicated on the speedo. This has nothing to do with the odometer which uses a different sensor.

the odometer is not biased upward. and how did you measure 0.5 miles? i highly doubt that your odometer is off by 40%

I have been researching it and actually read that thread before i posted haha. Just wanted to see if there was a fix for it, it's annoying cus i drive 90% freeway. I'm going tomorrow for something else and was going to bring that up.

You can't do anything about the speedometer reading 2 - 4 mph high. The odometer should be virtually 100% accurate and it would be rare if it is not. But, if it is not it is certainly a warranty repair issue.

I coded the v= speed on the OBC, then coded the correction factor. The v= speed then was pretty much spot on with my GPS. Now I have actual speed and BMW speed. I think you can code it so the speedo gauge to read actual speed too but I have to check, it's been awhile since I did it. Moral of the story, yes there is a way but the dealer won't do it for you.
