At the last seminar I was at, the man from VOSA said that they weren't planning on introducing the engine MIL as a fail item 'as any engine management faults would show up on the emissions test'.

Mind you they/we are being dictated to more and more by Brussels.:(

Hi
no the engine management light is not part of the test yet and to be honest I cannot see them ever being so, The reason is that of some cars vauxhall for instance the management light can come on for a faulty oxygen sensor heater circuit although the CO readings will be perfect.a slight drop in signal from a crank or cam sensor will bring it on although the ecu's on many cars are smart enough to keep the car running. The old rovers(200,400 etc) would run without a coolant temp sensor, the ecu would assume a coolant temp of 80c and fuel accordingly, they may be difficult to start but once caught on the throttle after 5 mins they run perfectly,and pass the emission test. Mercs and VWs which will bring it on if the ECU finds the Co reading I drifting slightly (from the second after oxygen sensor), although its still a pass.
I sometimes wonder who is bringing in the rules and have they ever worked on a car or have knowledge of modern fueling and emission systems.
IF it did come in I would have no problem with you resetting it and representing it,to me its the same as you replacing a stop bulb.

It isn't in the test. Don't worry about it.

Might come into the test in the next few years though.....

Hi, I have a SEAT Toledo that has an intermittent engine management light come on. I've checked the code and it refers to the secondary air injection, an incorrect flow is detected. Secondary air injection is only used to warm the car up quicker, which ties in with when I see the code. It only appears perhaps once every half a dozen journey starts, and if I reset it using a reader it doesn't reappear for the rest of that journey.

Now knowing my luck it will come on when the MOT tester moves my car into the test bay. So a couple of questions. First, is an engine management light an MOT failure now? There was mention of new rules coming in this year, I can't find out whether the EML is part of the MIL checks that are now part of the MOT. Second, if it is, would the MOT tester allow me to reset the code on the car park and re-present it immediately?

I should point out that I have no other warning light issues, so ABS, ESP, seatbelt lights etc all come on with the ignition then go off after a second or two.
