Don't stress if you come across error code B7F668 on your BMW F10; You probably won't see it in your active codes as it's usually in the "inactive / historical" section. The code simply indicates that the system time was reset at some point, which can happen if you reprogram the KOMBI system, disconnect the battery for a long time, or reset the system's voltage. You shouldn't experience any actual problems with this diagnostic trouble code (DTC); if you're having performance issues, it's likely due to another issue. The main hassle with B7F668 is that it may persist even if you can't clear it. Fortunately, dealing with this is one of the least troublesome issues you may encounter with BMW's "German Engineering"!

My 2019 BMW 430i recently displayed a code after I filled up with gas from a new station. Despite emptying the tank and refilling it with higher octane gas, the check engine light remains after four days. Would it be advisable to disconnect and reconnect the battery terminals to see if that resolves the issue?

Hey there! I had this issue with my car for about two weeks. I took it to a professional who diagnosed the problem as a faulty EGR valve, which was causing the check engine light to turn on. I replaced the valve and now my car runs perfectly without any issues. The repair cost me $300. Just wanted to share this in case it helps someone else out.

I received a code when I put additives in my diesel tank, and it keeps reappearing. I just realized there's a warning on my fuel lid not to add additives. I hope my BMW F10 will be okay after I fill the tank with regular diesel.
