2009 M3 vs 2011 + M3 Computer Flash

2009Cabriolet · 08-19-2012, 09:18 PM

I'm new to the M3 brethren, and have been slowly reading previous threads to learn more about my newest addition.

I'm trying to confirm whether there is a difference between my model year's and newer M3s computer flash, and if so, what are the differences and should I be requesting this update?

Thanks, and keep the good information rolling!

Yes, the software on your car may be different from what comes on a newer car. For the most part, the dealer will not update the software unless your car has a problem. You can pay for the service if you like though.

I just had my car reflased due to a new amp being installed and my MPG has gone up almost 1 mpg and I am driving the same as I have always driven.

Thanks for confirming. Any recommendations on where to go if I'm willing to pay?

Unless you have an actual problem with your car I wouldn't bother paying real money for the latest BMW software (aftermarket coding or engine tune is a different story though.) Unless you have a problem (in which case BMW buys your software - at least here in the US that's the case, not sure about Canadian warranty) you're not going to see any appreciable difference in performance and whatever you bought would be replaced or wiped out by a subsequent dealership service visit.

Thanks for the information. I think I'll start looking into aftermarket flashes then, as I'm a big proponent of maximizing the stock package.

Desert BMW did mine for free but if any modules failed, i would pay for the replacemnt module out of pocket. 20 free hp i guess.
