Question

where is the camshaft sensor b in babk 1 0n a 2002 audi a6

Answer 1

Bank 1 is where cylinder 1 is located, Audi does not use  a sensor B to reference their camshaft sensor, Audi uses G40 or G163 as their identification for the camshaft sensor, Depending on the scan tool you use it can give definition such as camshaft sensor A" which on some scan tool mean its reference voltage, or uses "B" for the signal return. If you post the code it would be easier to identify which sensor it is.
