Good question! I never thought about this before, but if you're using an 
oxygen sensor type of system, then the sensor has to be HOT, and there is 
no place on a VW system that will be hot AND in line with the exhaust from 
ALL the cylinders. Quite a dilemma.

I would think the bus would have the same problem.

The old Heathkit meter that I have runs off "cool" exhaust gas, so it just has 
a tube you stick up the tailpipe. This is hard to do while driving, however.  ;-)
