in my opinion Autohex is overpriced in terms of that annual fee. Most likely the last years payment I paid for subs was the last one from me I waited a couple more years but no development at all just some rear database updates. So no point to do it as all the module updates, codings, you can easily do with Standard BMW tools and ESys with always the latest up-to-dated files without waiting for new versions from Microtronik. There are some other features linked to they servers which requires subscription like FEM jobs, CAS3+ downgrades, some others. But now there are quite a few cheaper options in the markets together with some leaked info on E/F series I think you can do most of the jobs without Autohex.
In general very nice tool, but annual fees are ways too high imho there shouldn`t be any from 2-3 years ago.
