Original injector part number for E400 injector?



I pulled my driver's side fuel rail and injectors today, intending to change one failing injector.
What I found (I don't think car has ever been apart) were injectors with part number A 278 070 06 87, my replacement part was A 256 070 01 87.
I installed the new injector (believing it was a new part with a superceding, but compatible PN), but I could not get the injector coding to work.
If anyone has taken their factory E400 (M276.8 3.0L TT) injectors out, what was your original part number?

Thank you for the link, the original part number I found in my car is what that site lists, but it also lists an analog PN, I've never seen mentioned in the US. Interesting.
Hundreds, if not thousands of people have used Autel devices to code in MB/Sprinter injectors and other bidirectional tasks like teach-in and adaptations, if I need to pay for the MB xdos through Autel (my scanner supports that function, but I've yet to need it)... You could have just said that.



This was "operator error." My Autel subscription had run out, and I didn't realize injector coding required the MB SCN online capability.
Rather than pay $800 for a renewal for the MS909 I just got a Launch X431 Elite V2.0 BBA. It worked without issue. Life time subscription for Benz, BMW, Audi.
The replacement fuel injector part number above works fine, even though it wasn't listed on the website in other comments.
