I’m new to the disco world having upgraded from a freelander. Do you have to remove the headlight bulk in order to replace a bulb as can’t see how you can get into them from behind

I’ve got a P1E30 fault code and seem to lack power in low gears. I’ve checked the hoses and changed the solinoid but the light won’t seem to reset. Any suggestions on what else to try??

I’ve some how managed to pull the shirt vacuum hose of my EGR valve and don’t know where it should go to put it back
