ISSUE

A customer may report that during certain driving manoeuvres there is a groan noise from the suspension that lasts approximately 1 second. The main driving manoeuvres associated with this are:

  1. Steering right and then hitting a bump/ridge in the road very soon after.
  2. Steering to the right and then sharply steering to the left.

CAUSE

This is caused by the fluid moving within the DYNAMIC RESPONSE VALVE BLOCK combined with rapid system pressure changes.

ACTION

No action to be taken - this is the standard operation of the system.
