Great app. Easy to use. My ONLY issue is that expert mode, to me, is like having direct admin access to ur car's modules, except that it's 100% in German. I did email the developer and they said basically what I just said. But absolutely worth the money! Pays for itself after one time of coding. I did a search after thinking bout it but there are screen translators and that actually helped a bit with expert mode, just to peak around. I wouldn't recommend expert mode unless u know what ur doing

Really, all cars should have the ability to be coded to some degree. In this case, I've been able to code a couple of items that helps me to customize and further enjoy my in-cabin driving experience. Understanding the menu of coding options is intuitive. As well, there are many YouTube videos about things that can be done. At $60 for this tool plus the one-time "enrollment" fee, it is a solid investment. I only wished that Bimmercode would publish some unique Expert Mode tutorials.

I paid for a full subscription in 2019, and was told that it could be used anytime thereafter. I attempted to use it again recently with the same credentials as before, but I'm being instructed to pay full price (again), which is now $10 more. Customer support only responds with instructions on how to reinstall the app claiming it would then work, but it won't. Proper customer service would have been to a have a record of the purchased subscription on their end, to assist and resolve this issue.
