If the MAF sensor is bad, it won't be long before the CEL is back on.
Regarding the ATF, I checked WIS and found that Shell ATF 3403-M 115, and Shell ATF 3353 are both approved for use by MB. The latter will also work in the 722.9 seven speed transmission.

Can't seem to locate the Shell products listed above. Are there other approved tranny fluids? My dealer is not very close. Also, my local parts shop has a fluid that says it is for use in MB printed on back of bottle, Would that mean ALL MB including my ML?
Thanks!
