Thought I would update this. I just did the next service 2 yrs later, while doing the epic oil cooler seal replacement.

I took the car to the dealer afterward to make sure there were no codes stored and to do the adaptation on the new MAF sensors I installed as part of the new "bat wing" assembly.

Turns out that even if you just replace the air filters then you have to do the adaptation on the MAF sensors with the Xentry system.

So your options are to pay for an hour of shop time at your MB dealer, find a willing indie with Xentry, or buy a bootleg Xentry off e-bay.
