CONDITION SUMMARY:
Situation: A potential issue has been identified with the Dynamic Response valve block on certain 2014-2015
Range Rover Sport (L494) and Range Rover (L405) vehicles (5.0L S/C VS only) within the listed VIN ranges.
Unexpected body movements when the vehicle is stationary may be experienced due to the system self-test
pulse resulting in pressure in the actuators which is normally isolate from them.
Action: Retailers are required to HOLD only affected vehicles that are within your control and refrain from
releasing the vehicles for new or used vehicle sale pending completion of the rework action detailed in this
Technical Bulletin. Unsold vehicles should have this performed as part of the Pre-Delivery Inspection (PDI)
process but must have it completed prior to vehicle handover to the customer.
