W166 Service Bulletins
I've had my ML350 for 6 months now and have no reason to bring it in for any service. Is anybody aware of any service bulletins that we should be aware of? Thanks

Seems like the BlueTECs have had the most common issues (errant low DEF warning and rough running on cold startup). Not sure how those issues have been documented to the dealers.

I suspect there may be something coming due to the random stalling issues in the gas models. Possibly related to the high pressure fuel pump.
