I had a check engine light while driving.The scan shows code P0410-Secondary air injection: (fault function chain)Air flow is too low.
I checked all the relays,fuses,vacuum lines.
Replaced the post catalytic o2 sensor.
Erased the code and returned on driving 2 miles.
I notice smell of gasoline on and off in the car and rough idle as well.
Planning on changing the canister purge valve.
Sir, waiting for your expert comments.

I think you are on the right path. This issue is more then likely the purge is stuck open or closed.

I attached the testing that needs to be done but Mercedes requires a scan tool for most all their tests. So if it were me, I would replace the control valve and go from there.

Please let us know what happens with this as I am curious to see how this turns out. Thanks

Good morning Sir.

After almost 9 weeks I received my shipment (it was delayed because of Covid) hence I didn't contact you. I replaced the purge valve with the new one I received and cleared the code P0410. No CEL after that. So it seems that the purge valve was faulty.
Thanks for your valuable support, your advice is highly appreciated. Have a blessed weekend,bye.
