Hi Does sound a little extreme, this may sound stupid but I'm sure I removed mine for some reason this year, think it was to replace the radiator, although not sure it was absolutely essential to do the radiator job.
Anyway I'm sure its on the left hand side of the car under the front wing. To get at it you need to remove front left hand side wheel arch liner. It has these little plastic clips that are something like rawlplugs with a plastic screw in the middle. you need to dig the screw out to remove the clip, useful to have some spares when you do the job. This then exposes the washer reservoir, disconnect the cables and hoses to the two pumps then remove the bottle. Awkward to get at so you can undo the bolts that hold the reservoir move it away from the body then do the disconnections if required.
It could be a damaged hose and the bottle may not need removing best have a look and see. I'm sure you definitely do not need to remove the wing. Richy
