Hi im a newbie had my 2008 2lt for a week today and loving it.
Ive managed to blow a fuse messing with the courtesy light bulb its taken out the stereo the central locking and engine management light on. Could anyone tell me which fuse this is or more so its location. Thank you
Have a look here
The small fuse board is on the passenger side inside the cabin at the base of the A pillar, remove the small plastic door. The main fuse box is in the engine compartment, passenger side next to the air filter box. Could be the room fuse you’ve knocked out in there?
I’m surprised that would affect rhe engine management light.
Are you sure you haven’t got water in the fusebox
from the infamous grommets??
Check for wet carpet in the passenger footwell.
All ok now fuse replaced and all good thank you
Room fuse? 
Sure was thank you. 
ROOM fuse supplies battery back up to the PCM, hence the engine light coming on.
Thanks for the explanation
