Check Engine Light
So it finally happened guys. Have been driving my brand new c43 and only put 2259miles on it when the dreaded CEL came on today. I already set up an appointment with the dealership I purchased it but would like to know what was the experience like for anyone that was affected by this. Did it get resolved, did it get lemon, did a buyback occur? Anything really just want some more information for when i go to get it serviced.

in my experience none of them work on w206. I've tried the best and very expensive. The car is listed as it's scannable but in reality it is not. Let us know if you find one that works.
CEL on this car will reset after about 18 hours. It could happen for reasons that should not be alarming and others that are. I would say that if it does go away after that 18 hour period then don't worry about it.

The Launch scanner has on its main screen a box labeled OBD. Selecting it causes the Launch to scan for the all the possible OBD protocols. The scanner reports all failures doing this?

I started it up like normal today and it was gone so you may be right for now. I really hope it was just a glitch because other than that im loving it

it lets you select 206, scans it, then says it's not recognized. I don't have any of them now as I tried a few best ones and had to return but that's what I remember.

Sometimes it's only the VIN that's not recognized, and it and the vehicle information have to be entered manually. Was this the "not recogized" event, or did the VIN and vehicle info register, but things crashed thereafter?

so you can enter 2 ways, wither by auto vin recognition or actually search for the chassis number. Again, at the end of scanning, no data appeared but the message that car is not being recognized. The support actually remoted in, but couldn't fix it. Referred to development team who couldn't do anything either. I tried several expensive scanners, always the same result. I heard somewhere, 206 and 223 and perhaps others have a security wall.

This is all very interesting because as you might be aware, "right to repair" laws are being passed that require manufacturers to provide enough information to owners to make basic car repairs. Locking out scanners and then disabling a vehicle that requires it be taken to a dealership for repair will not be permitted. Locking out re-coding as BMW has done is one thing, but denying an owner the ability to scan for emissions sufficiency is quite another. Much of what's going on with new automobiles is encouraging me to keep what I have and not buy another. Maybe when sales plummet, they'll wake up.

2023 C43
I must have the worst case scenario with the CEL coming on. Mine came on after 6 days on my 2023 C43. When I took it to the dealership, after a few days, they told me that due to a manufacturer's defect, debris was getting into the radiator. After a week or so of attempting to remove the debris and flushing the radiator out numerous times, the dealership told me that it could not be fixed and that I would require an entire new engine!! They also said that the engine is on back-order with no scheduled ETA.
So far, as of this post, my car has been in the shop for 30 days with no end in sight. They are currently attempting to reach out to MB to see about buying me out of the car and/or other options to get something else. The dealership has been wonderful but so far owning this car has been a nightmare!
