Tried again late yesterday, still not managed to get them off no matter how hard i try, used shed loads of wd40 and although i manged to loosen the clips of 2 of them the bloody pipes would not budge. In my frustration whilst stomping around i stood on my scuttle thingy and snapped a corner of it

. With a bit of luck i can get those 2 off but how i the hell i can get the one from the passenger side off beats me. I am ok to go disconnecting other pipes etc in that area so i can get better access as long as i remember where they go?
Shall wait until the skin has grown back on my knuckles until i try again.

thanks
Steve
