Land Rover Discovery Owners & Service Manuals

Land Rover Discovery: Fuel system

  • Under no circumstances, should any part of the fuel system be dismantled or renewed by anyone other than a suitably qualified vehicle technician.
  • Make sure sparks and naked lights are kept away from the engine compartment.
  • Wear protective clothing, including, where practical, gloves made from an impervious material.


Land Rover vehicles are fitted with emission and evaporative control systems.

In many countries it is unlawful to tamper, modify or renew such equipment and legal penalties apply if the laws are flouted.

Retailers/Authorised Repairers are properly equipped to perform repairs and to maintain these systems.

Exhaust fumes contain poisonous substances which can cause unconsciousness and may even be fatal.

  • Do not inhale exhaust gases.
  • Do not start or leave the engine running in an enclosed unventilated area.
  • Do not drive the vehicle with the tailgate open.
  • Do not modify the exhaust system.
  • Exhaust leaks should be repaired immediately.
  • If exhaust fumes are thought to be entering the vehicle, have it investigated immediately.

Note: Running out of fuel can result in a misfire. This can cause damage to the emission control system.


If the lighting has just been switched off, give the bulbs time to cool. Handling them when hot may cause personal injury.

  • Always replace bulbs with the correct type and specification. If you are in any doubt contact a Retailer/Authorised Repairer for advice.
  • Before attempting a bulb change, make sure the ignition and affected lamp are switched off. If the circuit remains live, a short circuit can occur which may damage the vehicle's electrical system.

Not all bulbs are renewable. The following bulbs can be renewed:

All other exterior lamps and some interior lamps are either LED (Light Emitting Diode) or Xenon units and can only be renewed by a Retailer/Authorised Repairer.

All replacement procedures require the removal of components to gain access to the bulbs.

Moving a headlamp unit should be undertaken only by a qualified technician. If in doubt, consult a Retailer/Authorised Repairer.

Note: To change any bulb in a headlamp unit, a cross head screwdriver and a 10 mm spanner is required.


  • High voltage is required to ignite the gas and metal vapour which are used to power Xenon lamps.

    Contact with this voltage can cause serious injury. Replacement or maintenance of Xenon lamps should only be carried out by suitably qualified personnel.

  • Xenon lamp units operate at a very high temperature. Make sure the lamp units have cooled before attempting to touch them.
  • Xenon lamp units contain mercury which is highly toxic and can be extremely harmful.

Seek advice about the correct disposal of Xenon lamp units from a Retailer/ Authorised Repairer, or your local authority.
