dicovery 4 SDV6 2012 limited performance

Hi Guys.

Im a newbie on forums and owning a disco so please exscuse lack of knowledge. We just purchased our first disco. Its a 2012 auto SDV6 XS with a 110,000 miles. The kids fell in love with it on the test drive all the space and sports mode lol. But unfortunalty our first trip on the motor way resulting in the car going into limited performance. This clears after car is switched off and locked but has come back on everytime i try and go on moroway again. Its fine around town no matter if you drive it steady or put ur foot down. I returned it to the garage and they plugged it into diagnostic and it came up with a MAS flow error. apperantly its the sensor on the inlet manifold. They are ordering a new sensor, but i thought the sensor was saying the air in the intake was wrong not the sensor.
Has anybody ever had a issue similar to this or know of one please? Just worried now as we love the car but are scared it could be somthing big as theres a lot going on before the inlet manifold that could be wrong.

many thanks in advance for any help or info

Cheers

Scott

Was the fault mass air flow fault or map fault as there 2 different sensors.
