Vehicle came in with misfire condition, tried to scan but no comms. Checked misfire condition, turned out to be faulty injector, replaced injector car now running OK, but I cant extinguish the M.I.L. which was flashing for a while and is now permanently on.
I tried scanning the other systems out of curiosity but can get no comms on anything, checked all fuses OK tried EOBD on to different scanners and vehicle specific software on two different scanners! Anybody got any ideas where to go now?

Cheers.
