190e 2.3 failed emissions, I do not have the original catalytic converter, but a midas one.

Do you think this might be the cause? Is there some way I can "cheat" on the emissions test by using a certain fuel or making an adjustment to the car?

Should I buy the fastlane catalytic converter for my car here? Do you think that will solve the problem for sure?

Btw, the dealer quoted me $1800 for a catalytic converter!! Why so expensive!!!?
