It is a 2018 TT so I am hesitant about rewiring the whole thing. I will explore the whole system again. I can never reduplicate it without driving hundreds of miles. I appreciate all the suggestions. I thought about replacing the magnet in the suspected wheel first.
Your first post said "2008 TT", never the less if you think these things are made correctly think again. My KZ had one brake wire crimped on the insulation, so only three worked.
Since your controller reported a disconnect, I would think that three brakes working would not cause the warning. Also, a short is probably not the issue.
