This very welcome news comes from Aaron at OutMotoring.com:

Well after a threatening letter requesting that my 03 MCS be replaced under the Ohio Lemon Law, I got the newest software that has not been released to the dealers and it actually FIXED the stumble. The low RPM 1st gear stumble is gone. No more waiting to pull out in traffic until there are NO cars coming. While I would have really enjoyed getting a new MINI, mine is just fine…FINALLLLLY! This is the newest update, not the issue 35 that recently hit the dealers. It does not have a release name/number yet, but has been tested in Arizona for the last 30 days or so. I just happened to bug them at the right time when the software was close enough to being released that they had it loaded to my DME/ECU.

For all those out there that suffer, get in line, the software should be released soon and your dealer can upload it without shipping your DME off to MINI.

Now I can install that ALTA exhaust that's been sitting in the shop for the last week!

Wow this is great news!!! Thanks Aaron!
