Won't pass inspection...
I'm about to take possession of a 2001 ML55. I bought it from my indie mechanic and it's ready to go, except he's having trouble getting it to pass inspection.
It won't get past these two monitors- secondary air pump and the evap system.
He's been working on German cars for over 30 years, so he knows what he's doing and this has him stumped.
He's tried every trick in the book and still no go. It only has to pass one more for him to put an inspection sticker on it.
I thought one of you might have had the same issue.
Thanks for any suggestions you might have.

EVAP system will probably need a smoke machine to check for leaks. On a 20+ year old truck I’m sure there’s a crack in a hose or some other air leak holding you up.
Good luck! 👍

Thanks. I sent your idea on checking the evap for leaks to my mechanic.
He replied that there are no faults for anything. He also said "The problem is that the monitors won't set for the evap and secondary air".

He reran the test first thing in the morning after a cold night and the monitors reset.
Good thing too. He left for vacation after work yesterday. If it didn't pass, I would have to have waited at least another week.
