Yes - I was running an ESS tune with the minimal cold-start. I really like not having the car sound like a bag of spanners when I start it up on a cold morning, but it's also somewhat obvious to a BMW service technician.

For the moment, I'd rather not have any warranty arguments! ;-)

Don't get me wrong, ESS were pretty helpful and responsive at getting me the new software, but there's an important difference between 'updated software version available, please upgrade at your convenience' and 'license expired, you can no longer run this program'
