Hi..

 

Hopefully i can help..

 

The only ways to get the engine management light out are as you may have done already in which you unhook the negative lead on the battery for upto over a 1 minute roughly and the hook the negative cable back onto the battery and that "should" wipe the ecu fault memory and turn the light off - the other way as you may know will be via diagnostic tool which would be able to do that quite quickly/ or suitable code reader able to erase fault codes..the engine management light will only go out once the fault has been rectifed/solved and the ecu see's nothing at fault...i do hope this helps
