All done! It took around 2 or 3 hours of actual work and probably another 3 hours of procrastinating/reading/thinking.
It is not that hard once you actually start.
I would recommend taking out the drive shaft on the drivers side as it does provide a lot more access; it can be done with out doing this, though I needed to replace the boot on the driveshaft anyway so it made sense.
Also remove the small plastic wheel arch shroud that covers the crank pulley/aircon compressor.
I started by removing the old octopus and cleaning up the area, taking note of the different routes, plastic sleeves, diameters of hard plastic pipes etc. Take your time with this, and ideally refit the new octopus the same day so that it is fresh in your mind.
I fitted the new octopus through the following steps:
- Using closed needle nosed pliers dipped in LHM, gently stretch and lubricate the internal openings of the new Octopus
- Feed the longest pipe on the passenger side of the octopus that goes off to the passenger strut return into the sleeve along the subframe and place the Octopus pod in position under the height corrector
- Using long handled needle nose pliers push the hard plastic passenger strut return pipe (Black 5mm) into the forward passenger side of the octopus (as per diagram).
- Using pliers push the hard plastic priority valve return (White 4mm) into the other passenger opening on the octopus (as per diagram)
- Feed the passenger strut return pipe through the sleeve and onto its corresponding metal pipe.
- Feed the three tank returns up and around the engine/under the brake valve/through the sleeve on the chassis rail and onto the reservoir as per the diagram below. I marked each with different coloured tape so I knew where they fitted onto the reservoir.
- Push the Hard plastic (Black 5mm curved) drivers strut return pipe into the hole on top of the octopus.
- Working from the drivers side of the car, sitting in the wheel arch with the view of the photo below: Connect the two hard plastic pipes (Rear height corrector 4mm and suspension return 5mm) to the corresponding points on the octopus. This I found the be the most difficult part of the process as access is limited. Use those long handled needle nose pliers!
- Connect the front height corrector return (small pipe that usually fails) to the height corrector.
- Cut the drivers strut return pipe to length and fit to corresponding metal pipe on chassis.
