NHTSA Complaint #11610832 — 2011 MINI COOPER CLUBMAN

I've just gotten a very common air bag seat mat sensor code (93c1) that Mini had a limited recall on - but alas my car did not get the code until it was outside the parameters of that repair program. What makes it worse is that the fix is over $1000 and there's very little concrete info on the actual danger (or not) of driving around with this code active. I've spend the better part of 2 days researching how to fix this & I'm still uncertain as to what to fully do.
