Engine light staying on is a failure, and could have a number of causes. Time for a cautionary tale. We bought a Discovery 2 some years back and took it for several MOT tests over the years. One year, we took it to a different garage. which failed it as none of the warning lights were illuminating at switch on. I nearly fell over. I didn't even know it was modern enough to have warning lights, but it had 3 that needed to come on and then off after the systems check is completed. (search the three amigos). I explained that this was a new one on me, but it was a major. Long story short, previous owner wouldn't spend money on correcting the faults, so removed the front dash and covered up the three lights. With the covers removed, the lights were on all the time, so another investigation ensued, resulting in another ABS unit being fitted, all three lights now off.
