TBH I've done the lift scuttle up route many times, but it is a damn site easier to remove wipers which is a 3 minute job at most & remove panel as its only clipped in, 5-10 mins job at most, then do the job at hand & refit, cause you can easily snap the plastic panel lifting it up tbh & squeezing your hand & socket/spanner in there is a pita, when you can easily remove the offending parts til job done.
Why I didnt do this before is beyond me I tell yer, I only realised 2 weeks back the poxy panel was clipped in place & lifted out so easy, was unreal.
