I seen details on various other forums of the additional item that will be included in the MOT from 1 January 2012. As there seems to have been nothing posted so far on this particular forum I will add those details... 4.1.4 Compliance with requirements: (a) Lamp, emitted colour, position or intensity not in accordance with the requirements (b) Products on lens or light source which obviously reduce light intensity or change emitted colour (c) Light source and lamp not compatible 4.1.5. Levelling devices (where mandatory): (a) Device not operating. (b) Manual device cannot be operated from driverâs seat. 4.1.6 Headlamp cleaning device (where mandatory): Device not operating. 6.1.9 Engine performance: (a) Control unit illegal modified. (b) Illegal engine modification. (by 'illegal', it is assumed that they mean changed/programmed differently from OEM specifications) There will also be a new check on the general condition of the wiring: 4.11. Electrical wiring (a) Wiring insecure or not adequately secured. (b) Wiring deteriorated. (c) Damaged or deteriorated insulation and on the function of airbag and seat belt pre-tensioner systems: 7.1.4. Safety belt Pre-tensioners: Pre-tensioner obviously missing or not suitable with the vehicle. 7.1.5. Airbag: (a) Airbags obviously missing or not suitable with the vehicle. (b) Airbag obviously non-operative. 7.1.6. SRS Systems: SRS MIL indicates any kind of failure of the system. One item I'm particularly pleased to see is the requirements for Lighting which should mean that cars which have had Xenons added to headlamps designed for Halogen bulbs and have also done so without including the required levelling and headlamp washing will fail an MOT. Quite how an MOT tester is going to tell in connection with Engine performance if (a) Control unit illegal modified, (b) Illegal engine modification has been done I'm not sure. Some engine mods will be obvious but a remapping will be much harder to spot!
