Okay car has 99.4 and its asking for a B1 now.

This means a B14 (sparks, t belt) should pop up like 107k

Does this sound right?!?

 

Yes. The average interval is 7k miles. 105k/7k = the 15th interval. This is just an average, though. The biggest contributor is resetting the mid before or after 7k exactly. The system also can monitor driving conditions and change the interval slightly.

 

Switched to B14 now ....
