Frequently asked questions

What does the NCL100040 relay do?
The NCL100040 is the glow plug relay for the Range Rover L322 3.0L TD6 diesel. It switches the high current to the glow plugs, controlling the pre-heat cycle that warms the combustion chambers for cold starting and post-start glow. The engine management system triggers it.
Where does the glow plug relay sit and what controls it?
The glow plug relay feeds the glow plug supply on the L322 TD6 and is commanded by the engine management system, which sets pre-heat and post-heat timing from temperature. It belongs to the diesel pre-heat circuit rather than the main starting circuit.
What are the signs the glow plug relay is failing?
Typical signs are hard cold starting, extended cranking on cold mornings, or a glow plug warning light on the L322 TD6. A failed relay usually stops the plugs heating, so symptoms show worst in cold weather. Warm starts are often unaffected, which can mask the fault.
Which Range Rovers does this relay fit?
This glow plug relay fits the Range Rover L322 (2002-2009) 3.0L TD6 diesel, up to VIN 9A999999. It's specific to the TD6 pre-heat system, so confirm your engine is the 3.0 diesel rather than a V8 petrol before ordering.
