Steve, thanks for that post. Very, very informative.

I've wondered what the new 'sw' limits were; could tell that the limits were increased because 'hex' numbers were larger, both positively and negatively. But MB really increased the limits quite a bit. No wonder the CE due to DTC 19 was fixed.

Are you saying the the MAF sensor was the 'cause' on the 600SEL? So replacing it, fixed the problem?

May I add this 'gist' of this info to my page under LH-SFI menu?
