Engine malfunction indicator lamp (engine management light or ‘EML’)
Turn on the ignition and check that the engine malfunction indicator lamp (MIL) illuminates and then goes off. On some vehicles it will be necessary to start the engine before the MIL goes off.
You need to inspect MIL fitted to diesel vehicles including hybrids with 4 or more wheels and first used on or after 1 July 2008.

(g) Engine MIL inoperative or indicating a malfunction (Major defect)
I have a 56-plate Mondeo diesel which failed the MOT due to my MIL/EML light coming on during the test.
I am trying to get to the bottom of the fault (EGR related codes P0403, P0405, P0409) but people are telling me the MOT tester has made a mistake so it's not necessary to fix it....
There seems to be different interpretations of the guidance above:
Does anyone know the actual rule(s)?

There seems to be different interpretations of the guidance above:
- some say the tester can ignore anything MIL-related if the vehicles was first used before 1/7/2008
- Some say that if the light stays on it's a fail no matter what age the vehicle is
Does anyone know the actual rule(s)?
