Ok, what did i try to say?
0280218088 has almost the same Diameter than the older Volvo ME7 Standard MAF.
The curve of MLHFM for 0280218088 is almost the same. It Ends at about 1200 Kg/h without MLOFS substracted.
The actual mass flow of the old MAF is around 930 Kg/h, your newer 0280218088 MAF is ending at around 1020 Kg/h.
One Bin which has the newer MAF is for B5254T
2 engine with 210 Hp.
I have attached the file from the Volvo ME7 Thread here - its impossible for me to find the entry in the thread
