I was looking for the 229.51 spec mobil 1 last week since it is the spec required for MB Diesel or at least for my 09 ML. I looked in every parts house, walmart, etc but couldn't find it. After calling Mobil 1 directly they found it for me at a distributor about 30 miles away.
I wound up buying 30 qts to cover 3 services.
I use 0w40 in my W210s and my W211 but the spec on the diesel is pretty clear and might be the same for the OP.
