On affected vehicles the incorrect specification of plastic was used to manufacture the oil filter housing. This housing may over time and with vehicle use crack. This could result in oil under pressure leaking and coming into contact with hot components of the engine which may result in a fire. Additionally oil may leak onto the road surface posing a skid hazard.

Fix: Replace the oil filter housing complete with filter and associated O-rings.

For certain 2023 Model Year 3.0L AJ20-P6 Land Rover Range Rover Range Rover Sport Range Rover Velar Discovery and Defender vehicles a small number of engines the cam carrier oil gallery hasn�t been fully drilled. As a result the oil channel could be blocked leading to accumulation of oil against the pressure control valve rubber membrane and subsequently an external oil leak or increased oil carryover into the air intake system.

Fix: The engine cam carrier will be inspected and where an incorrectly machined cam carrier is found replace it with a correctly machined component. Depending on mileage and engine conditions further associated components may require replacement.

It has been identified that the engine wiring harness of the 2.0ltr engined vehicles fitted with automatic transmission may have been incorrectly routed which may allow the wiring harness to contact the water charge air cooler bracket. Engine vibration can cause a chaffing condition where the outer sheathing of the cable can wear through and expose the wires of the engine harness. Depending on the orientation of the wires within the harness then damage to wires can result in electrical arcing and a short circuit. This condition can also result in the illumination of a warning light on the instrument panel loss of the electronic steering system engine cut out without warning melting of the cable sheathing and surrounding parts. Also in extreme circumstances it can cause an under-bonnet fire.

Fix: All affected vehicles will be recalled to inspect the clearance between the engine harness and water charge air cooler bracket. If the clearance is not to the correct specification the wiring harness will be repositioned and secured to ensure the specified clearance is achieved. If the engine harness shows signs of chafing the engine harness will be repaired re-positioned to ensure the correct specification.
