Peugeot partner - air flow too low

[locouk2]

Good evening!

Peugeot partner, 1.6 diesel, 17plate
Goes into limp mode, low performance and higher fuel consumption

Computer comes up with mass or volume air flow circuit a range/performance - air flow too low - p00bc

Maf sensor replaced, dpf physically off and cleaned

Any ideas? EGR?

Was the maf replaced with a genuine or pattern unit?
What live data you getting from it?

Sounds a bit like either the egr is stuck open slightly or you’ve got air being drawn in between the maf & the turbo unless your code means you’ve got a restriction in the intake side of the engine

Hi,

The problem (most probably) has been sorted
I just leave it here for future reference for anyone with same issue

In my case it was faulty EGR
