I don't understand your question. What do you mean by switching of the check engine light?

you know that yellow engine thing in the dashboard,it`s lit,can we turn it off?should`ve added the second f

I think you need to go to the dealer to have the code pulled... and they can reset it after repair. I doubt you can reset it from your dash. Plus, I don't think it's good to drive with the CEL too long.

Yeah, that indicates a malfunction within the emission control system. Take it to the dealer asap. If it blinks while you drive, pull over and have it towed. First check your gas cap, though. If it's loose, tighten it and the light will go away in a few days. If the cap is tight, it's probably a stuck purge valve. Dealer repair if under warranty. Could also be a slew of other things but those are the two most common on the C63.

By a OBD2 scanner, I just got an Autel AL309 (80$CAD) and you can read detailed error codes and clear them at will, very useful when it's just something minor!

you can pull the positive cable off the battery for 1 minute or so and the ecu will reset itself

My problem is that I removed the cats,I need to switch it off from ecu.

you can use a "o2 cel eliminator" which is just a spacer that sits between the o2 sensor and the exhaust pipe

I think you need to get a tune with the 02 sensor code(s) set to Not Reported for the rear sensors. Because it is illegal the DAS may not be able to do it or you may have trouble finding someone willing to do it for you.
