The January issue of Roundel contained some letters about the engine software for the 335s. I have a 335i that was built in 04/07, so it falls into the group affected by the engine software release that is mentioned in the article. I just had my car serviced by the dealer. I asked them not to apply any engine software upgrades because the car performs wonderfully. But, I think the standard policy is to apply the latest updates when a car is in for service. The car has iDrive. Is there a way that I can see what version of the software is installed on my car without having to go back to the dealer to find out?
