Keith's right, we've been oversimplifying it. It varies over quite a 
range depending on the operating conditions, but the only conditions 
it can be measured under by most shops will be at idle. 14.7 is the 
theoretical ideal number, but I'm not sure where most of our cars 
actually fall.

If you find a shop that has an exhaust analyzer, they will probably 
be most likely to measure CO levels. They may know what to expect, 
but they're most likely to be familiar with newer cars which will 
have lower CO than ours. I'm not sure what ours should be. I'd guess 
1-3%, but I could be wrong. I'm not aware of any specs that VW 
published on this for Type 3s.

Were there specs on this, Russ?
