I won’t resort to swearing, but it is an arse of a job to do on a right-hand drive car. Clearly, one of those things that works just fine on a right-hand drive. You need to undo the metal hydraulic pipes. The one on the bottom is the worst. If you’re in a turbo diesel, take the intercooler off (and block the intake with a brightly covered cloth so you don’t lose your spanners, nuts, sanity). The hard plastic return line I usually take out with the Doseur Valve, the other flexible pipe is part of the ocotpus and also needs disconnecting. Then, into the cabin, undo the two long bolts, and the valve will pretty much fall to the floor.
