Hi chris,
Put a new Mass Air Flow sensor in it and have the codes cleared. Also ensure your running a Genuine Landrover Air filter, NO K&N, as it it will contaminate the sensor. Also also ensure the air box is properly secured and that the alignment tabs on the sides are not bent into the box causing a leak and unfiltered air to enter the air intake.
There is a bulletin for this fault and it may also include a Fuel mixture adaption fault as well.
I can only guess but, It's possible your dealer changed the O2 sensors in error if they thought it would fix the fuel adaptions fault. D2 02 sensors are pretty reliable. If the code logged, when they changed the o2 sensor, was a P0171, p0172, p0174 or p0175 fueling adaptions fault then its far more likely that it's related to a MAF sensor contamination/failure.
Good luck. Please lets us know how it goes!!
