Diesel faults handled safely

Find HGV fuel-system diagnosis for leaks, contamination and no-starts.

Modern high-pressure diesel systems require clean working practices and specialist testing. If fuel is leaking, isolate ignition sources and follow your spill and emergency procedure first.

When this service may help

  • Cranks but fails to start
  • Fuel leak or strong diesel smell
  • Loss of pressure or power
  • Wrong fuel or suspected contamination

Leaks and spills

A roadway fuel leak may need emergency-service or road-authority involvement and environmental containment. Do not restart the engine until the source and fire risk are assessed.

Contamination needs a plan

If the wrong fuel or contaminated diesel is suspected, avoid running the engine. Tell the provider how much was added and whether the engine has operated since.

Frequently asked questions

Can you bring emergency diesel?

Use the dedicated emergency fuel delivery service and confirm the correct fuel, safe access and payment directly with the provider.

Can fuel-system parts be fitted roadside?

Some low-pressure or external components may be, but high-pressure work and contamination often require a controlled workshop environment.
