Could have been an oxegen sensor playing up. In the past when I had to take my Range Rover for an emmisions test I always drove it at very high rpm`s for 10 mins or so before going into the test station. This I learnt after 2 failures would clear any buildup from the sensor. I was given this tip by a RR tec. It then always had very low readings.
