Inspection And Verification
WARNING: This page is about a different car, the 2018 Land Rover Discovery Sport. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Wait at least 30 seconds after stopping the engine before commencing any repair to the high pressure fuel system. Failure to follow this instruction may result in personal injury.
Place the vehicle in a well ventilated, quarantined area and arrange 'No Smoking'/'Fuel Fumes' signs around the vehicle. Failure to follow this instruction may result in personal injury.
Before working on the fuel system, ground the vehicle to earth and maintain the ground connection until the work is complete. Failure to follow this instruction may result in personal injury.
Do not perform any repairs to the high pressure fuel system while the engine is running. The fuel pressure can be extremely high. Failure to follow this instruction may result in personal injury.
Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel related components. Highly flammable vapors are always present and may ignite. Failure to follow this instruction may result in personal injury.
After making repairs, the fuel system must be checked visually for leaks. Failure to follow this instruction may result in personal injury.
If taken internally do not induce vomiting, seek immediate medical attention. Failure to follow these instructions may result in personal injury.
If fuel is taken internally, do not induce vomiting. Seek immediate medical attention. Failure to follow this instruction may result in personal injury.
If fuel contacts the eyes, flush the eyes with cold water or eyewash solution and seek medical attention. Failure to follow this instruction may result in personal injury.
Wash hands thoroughly after handling fuel, as prolonged contact may cause irritation. Should irritation develop, seek medical attention. Failure to follow this instruction may result in personal injury.
This procedure involves fuel handling. Be prepared for fuel spillage at all times and always observe fuel handling precautions. Failure to follow this instruction may result in personal injury.

CAUTION:
Before disconnecting any part of the fuel system, it is imperative that all dust, dirt and debris is removed from around components to prevent ingress of foreign matter. Failure to follow this instruction may result in damage to the vehicle.
It is essential that absolute cleanliness is observed when working with fuel system components. Always install blanking plugs to any open orifices or lines. Failure to follow this instruction may result in damage to the vehicle.
Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.

NOTE:
If a control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures manual, or determine if any prior approval program is in operation, prior to the installation of a new module/component.
When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places, and with an up-to-date calibration certificate. When testing resistance always take the resistance of the digital multimeter leads into account.
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

Purge valve - If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step
- If the cause is not visually evident, verify the symptom and refer to the Symptom Chart, alternatively check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index
- Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific customer complaint and carry out the recommendations as required
