Engine Management lights?
As long as everything is running ok I've learned to ignore them. I just drain the memory now and then by disconnecting the battery on our 2001 Astra (make sure you have your radio code). It always passes the MOT. Been like that since we bought it nearly 5 years ago. I even serviced my father in law's Nissan Micra last summer - what happened? start her up and the light stayed on. Disconnected the battery. Nothing since. The old Frontera has never had any problems apart from warming her up too quickly on minus zero mornings. Then the light comes on. Just switch off the engine and start her up again. Light goes out.
Engine management lights were invented by the motor trade I believe to frighten people and extort large quantities of cash from them

Now what am I doing on a car forum on Christmas Eve I ask myself?
All the best.
