[W126 Coupe] Regarding emission equipment on engines..

[Mike R.]

Where are you located?

I failed emissions on my 560SEL in Vegas because they finally realized that 
I had removed the air pump. The emission numbers were fine, it was the 
"visual inspection" that caused the failure. I bolted the pump back on, 
added a belt to it, and hid the connector in a wiring bundle so it would 
NEVER get energized. Passed.

Don't take off too much "stuff" and fail the visual, which depends on where 
the car is tested.

Later,
Mike R.
Vegas, baby!
