B5254T4 is wrong on that list. It uses even bigger HFM.

Be aware, that Volvo might use other startegy of aquire ML.
It can be done with MLOFS and without.

Also min/max Diagnostics, electronical diagnostics and so on needs to be transferred.

Be also aware, that Volvo uses different HFM connector than VAG.
If we use VAG, a plastic nose can be removed and it must be turned and repinned.
I don't know if it all works in the other direction (Volvo -> VAG).

Files for other engine codes can be found in Volvo ME7 thread, although they might not be the correct ones for that HFM too.

Volvo uses same Bosch Number of Ecu for different engines and chassis, don't use that to get further.

If you know the maximum ML (airflow) you are looking for, it might be a better strategy to search the files you can obtain for that max value.

So what is your indicator of 'having no luck'?
What are you looking for in the file?
Which max HFM Flow do you seek?

Basically, Volvo uses only two HFM Sizes on ME7.
So you will most likely find always the same curve, expect for late 6 Cylinder Turbos or the B5254T4 / B5244T5 Engine.


Then there is a difference for the smaller HFM: using separate Temperature sensor or integrated HFM Temperature Sensor. That's why there are different part numbers used.

I have nearly 200 different Volvo ME7 Bins, didn't saw anything else.


There is also a difference when the Software is using MLOFS or not using it, but it leads to the same curve if taken into account.

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 B5254T2 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

Yes, MLOFS = 200 Kg/h


As i said, ecu number is not important, this bin can be found in at least three different Bosch ecus (with different ecu numbers). Concept is little different compared to VAG.


Good.Luck.
