Issue as described below, this is the exact specific issue i have.  just wondering on a possible fix.. its real annoying

see here

Lights don't go off when key removed

ibrokeit talks about
'The reason being there is a known problem, on some FD i30 (don't recall details), where the spring for the 'key in ignition' sensor is a little weak.  Eventually build up of grim and/or change in grease consistency causes it to stick, resulting in the car sensing the key is inserted in the ignition when in fact it isn't.'

try WD40. it will dissolve old grease and grime.
then you can put in grease spray or thin oil.

While the wd40 trick did not work consistently in the beginning, it did I fact remove the problem entirely/eventually
