FFS! thats what i didnt want to do!
I have tightened it right back up. should that be ok?
It doesnt seem to budge, until that was loosened.
got some pics to clarify stuff
these bolts in red, are undone. but the cover wont budge.

haynes and bently say remove the rubber plug to get to allen key and "retaining clips" shown here

I have removed the rubber plug covering the clips but have no idea how to undo them as i cant see into them due to the angle.
circled here is what i un did and did up again. the arrow points to the clips.

Really dont want to take this to a garage for such a simple job.
how does it unclip?
thanks
