My vehicle is one with the winter pack, with two batteries fitted from the factory, so the below refers to this model.
Before doing this it may be prudent to disconnect the negative battery lead of the drivers side battery (although I didn't)
The washer bottle is held on by two bolts on the front of the bodywork, the bottom has a plastic extrusion which locates into the bodywork underneath.
Before I was able to remove the bottle I needed to remove the passenger side battery. I disconnected the battery leads (negative first), then unfastened the battery clamps sufficiently to allow them to be unhooked from underneath the tray.
There is now a session of battery juggling because the bonnet stay is in the way. Its best if you can get someone to hold the bonnet open for you while you lift the battery out, or re position the bonnet stay.
Once the battery is out use a 12mm socket/spanner to remove the four bolts securing the battery tray and once this is out you will need to use a 12mm socket on a long extension to remove the two bolts securing the tray support. The support is attached at the rear to a brake pipe with a plastic clip but you do not need to remove the support just manoeuvre it to one side.
Then undo the two securing bolts of the washer bottle (10mm).
There are two pipes leading to the two pumps on the bottle (one at the front and one at the back) along with two electrical connections (both are different so you cannot mix them up).
On mine the pipes were clipped to the bodywork but the pipes easily pull out of the clip.
The bottle also supports the wiring loom with a cable tie, rather than try to remove the cable tie from the bottle I used a small screwdriver to open the clamp and pulled out the strap.
First disconnect the electrical connections (squeeze at the sides and pull type) then pull the rearmost pipe from its pump. I then put my finger over the pump exit (cos the bottle was full) before pulling the pipe from the from front pump. There is an F and an R stamped into the bottle so you know which pipes to fit on which pump.
Once the bottle was out I gave it a good flush until I was satisfied the smell had gone.
Refitting is a reversal of the above procedure. I then filled it with some ready mixed washer fluid.
This job is probably a lot easier doing it than reading about it, it took me about an hour all in.
Hope this is of some assistance.
