Hi i am having intermittent issues, i keep on getting the engine management sign come up but then it goes away at times then comes back, had the diagnostic test done

Error code which comes up is

290900 - Air system, Air to Egr mass flow, plausibility : measured air mass compared with calculated air mass too high.

i have replaced the egr valve, air mass flow sensor, Valve, EGR exhaust control (EGR EXHAUST VACUUM SELENOID VALVE )

[535_BiTurbo]

what diagnostic tool did you use?

looks like ISTA-D.

So did anyone ever get to the bottom of this fault. I've the same symptoms and have replaced the same items. No joy.

EDIT: I finally got to the bottom of this. IT'S CURED !! YAY.

Thanks to all who pointed me in entirely the wrong direction lol.

Hi Chaps
Has anyone found a solid fix for this issue, @brianbelfast - i've noticed you've jumped on a few forums - did you ever get yours sorted?

I have an exhaust gas pressure sensor replaced at the tune of £137.60 and still not fixed!

Faults I have are:
290900: AIR SYSTEM, AIR TO EGR MASS FLOW PLAUSIBILITY: MEASURED AIR MASS IN
COMPARISON TO CALCULATED AIR MASS TOO HIGH

28DE00: EXHAUST GAS PRESSURE SENSOR BEFORE TURBINE, PLAUSIBILITY: EXHAUST
GAS PRESSURE BEFORE TURBINE DYNAMICALLY NOT PLAUSIBLE

Any help would be greatly appreciated.

Hey BrianBelfast
Any news on what you had to change to get this fixed, I’m tearing my hair out and the car was with a mechanic for a week.
