System Pipes

WARNING: This page is about a different car, the 2012 Land Rover Range Rover Sport and 2011 Land Rover Range Rover Sport. However, it is still accessible from the selected car via links, so may be relevant.

Fluid is moved through the Dynamic Response system via a series of six pipes and hoses. The pipes are mounted on brackets at strategic points to provide quiet operation of the system.

The six pipes connecting the pump, reservoir and actuators are one-piece components. If the pipes require replacement during service, the pipes are supplied individually and are removed and replaced in one piece. The front and rear pipes require the body to be lifted slightly to allow access for removal and replacement.

On TdV8 models from 2007MY, the high pressure hose and pipe from the pump to the valve block are available as two separate service parts. The high pressure hose has a quick release connector located in a position below the Air Conditioning (A/C) compressor. This allows the hose to be split into two parts to assist with service repairs. The connector is sealed with an O-ring and a back-up ring which are available as service items. A special tool is required to separate the connector. The tool is inserted into a slot in the connector, which separates the two components. It is not necessary to use the tool as a lever to 'push' the two components apart.

The flexible high pressure hose which supplies pressure from the pump to the high pressure pipe is fitted with attenuators. The attenuators comprise of tuned lengths of PTFE pipe and restrictors within the flexible hose. The attenuators damp pressure pulsations in the hydraulic fluid produced by the pump, reducing noise and strain on components downstream. The attenuator is integral with the high pressure hose and cannot be serviced separately.

CAUTION: Under no circumstances during repairs should clamps be used on the high pressure hose or the front and rear actuator feed pipes to prevent fluid loss. The use of clamps will damage the pipes and hoses leading to premature failure.
