There are at least 3 different Bosch testers. I have the less 
desirable of the late version: It has poor quality switches. The 
early version won't test the later FI cars.

I really don't care for the VW one. It doesn't tell you what it sees; 
it just tries to make the diagnosis itself and give you the answer. 
Unfortunately the answer is often wrong. I guess the problem is that 
it's smart, but not smart enough.
