Note: if Mercedes 229.x is NOT printed on the bottle, it's NOT a suitable oil for your car.
It's NOT on "turbo diesel truck" oil and it is on 0W-40 European Formula Mobil 1.

I completely disagree. Mobil 1 turbo diesel truck should be at least as good as 0w40 for your application. M1 0w40 is a fantastic oil and has high TBN, but 5w40 "TDT" is specifically formulated for diesel engines and has better soot & deposit control than 0w40. Also 0w40 shears rather quickly into a thick-30wt oil at which point it holds viscosity very well, while 5w40 "tdt" doesn't usually shear out of the 40wt range.
Manufacturer specifications are usually a good guideline for choosing oils, but remember that MB generally chooses one oil that will work with their entire product line (gas or diesel) in all climates. I have used both oils and found that both the '05 e320 cdi & '97 e320 ran a bit better on the 5w40 "TDT" out here in California. Now am running new 229.51-spec Mobil 1 5w40 ESP Formula M in the cdi and Mobil 1 10w40 "high mileage" in the e320...best oils yet for both cars.
Don't get me wrong...M1 0w40 will work very well in your diesel, but it is my opinion that:
M1 5w40 ESP Formula M > Mobil 1 5w40 TDT > Mobil 1 0w40

i agree with stickygreen on this one, mobil1 5w40 tdt would be my first choise for your engine. also rotella 5w40 would be a good choice in my opinion, and cheaper too.
