A few notes about the Land Rover Range Rover (L322 series):
Land Rover generally favour a product like Comma Xtech 5W30 for most of their applications however there are some exceptions, particularly in the newer models fitted with DPFs in this series.
Rear suspension bushes perished causing banging noises on rough road surfaces.
Fault code P0806 transmission issue, rear diff lock actuator seizes and requires replacement.
3.6D TDV8 intermittent misfire P1295 number 1 cylinder – engine bay wiring loom internal corrosion issues.
Engine immobiliser communication malfunction with engine ECU P1621 – poor wiring connections/programming issue.
Engine management coolant temperature sensors can be a problem on this vehicle, says Cambiare. The failure of this part can lead to poor hot or cold starting, high fuel consumption and/or poor idling. ETS faults are usually accompanied by a P0117 fault code.
Cambiare advises that technicians looking to address cruise control engagement problems should bear in mind that the cause could be related to a failing brake light switch, which signals the ECU as well as switching the brake lights.

It is notoriously difficult to identify the correct parts for this vehicle. To help with identifying them the vehicle’s version and motor number are required and these can be found on the chassis (VIN) plate.
When the old clutch components are removed from the gearbox carry out a visual comparison of the old clutch and Concentric Slave Cylinder (CSC) against the new. Don’t be tempted to ignore the CSC replacement when changing the clutch, remember it’s a bearing and the last thing you and your customer want is to be removing the gearbox again. Some variants are also fitted with a Dual Mass Flywheel (DMF). This should be checked when the clutch is being changed for wear.
The steering rack on the Alfa Romeo 159 is known for failing. If you can hear a knocking noise coming from the steering rack as you turn the wheel, and/or the steering is feeling heavy, then you most likely have an issue with the steering rack. The steering warning light may also illuminate on the dashboard to indicate this fault.
In certain cases, the factory fit rubber brake hoses on the Alfa Romeo 159 were not correctly vulcanised during the production process. As a consequence these brake hoses may partially or totally restrict the internal flow of brake hydraulic fluid, causing a significant reduction in efficiency during braking.
Poor switching properties at heat or cold.

Transmission oil of inferior quality.
Replace existing transmission oil through Tutela ZC 75 Synth.
The old transmission oil needs to be replaced with new one on all models when service work is done on the transmission.
Noises in the drive shaft(s) region and droning
The diesel engines used extensively across the 159 range are fitted with a Dayco High Tenacity (HT), or ‘white’, timing belt as its original equipment (OE) fitment. These units also feature a water pump that is integrated into the timing drive system and driven by the HT timing belt. Therefore, workshops undertaking either a water pump or timing belt replacement, need to realise that only by fitting a Dayco HT timing belt kit can they be assured of a genuine like-for-like replacement.
