Is there any negative reasons to NOT update to the newest daten files? My personal car in an 06 E90 so I would think the older daten files would be better. Please clarify.
You should search around here as that information has been discussed countless times.
Using old daten files on a newer car with later daten files can screw things up. The biggest one is Kombi, where the dials don't work when coding with an older release daten files.
To fix that, you need to recode the Kombi once you have the correct version (or later) daten.
I hope you are confident in your coding before coding other peoples car (saw your thread posting about coding services).
