The unit works well but as mentioned, when voltage drops below 10V all bets are off

So, I've been researching about what the Foxwell letter codes BD & D7 actually mean. I found no reference to them in any Foxwell or (limited) BMW info I have (not even a Bentley), but I did find info via the internet, on various BMW enthusiast sites. The most useful reference to those letter codes was found in some notes I had compiled prior to even getting the X5. I had a list of what I called "KOMBI codes".

Where I found it originally, I don't know when, or where, or from whom. It does agree with another list I found on Bimmerfest:https://www.bimmerfest.com/threads/instrument-cluster-fault-codes.1369463/post-13259319

Using that list (and the BMW abbreviations list from https://bmwsections.com/info/abbreviations.php, I did more searching, decided that : BD Electronic brake power on my list actually referred to Electronic Brake force proportioning, and found this thread https://xoutpost.com/bmw-sav-forums/...ebv-fault.html right here on XO.

As far as they could tell, and I tend to agree, it's a phantom, since I have no brake light lit up on my dash.
