Misfuel risk High
UK Discovery Sport Ingenium and earlier TD6/TD8 diesels are sensitive to petrol contamination. JLR common-rail systems can suffer HPFP and injector damage after a short run.
If the engine was not started
Do not start the engine or turn the ignition to RUN. Do not drive. Arrange GBIFDA-certified drainage before contamination reaches the high-pressure pump. Keep receipts for contaminated fuel disposal (Environment Agency / SEPA / NRW / NIEA duty of care).
If the engine was started
If the engine ran on petrol in a TDI, expect inspection of the high-pressure pump, injectors, fuel rail, filters, and low-pressure lines. JLR warranty excludes misfuel damage; follow TOPIx repair scope and consider insurer or Motor Ombudsman routes for disputes.
Access procedure
- Disconnect battery earth and confirm ignition off.
- Depressurise fuel system per TOPIx for your model year.
- Access in-tank pump module (location varies — under rear seat or beneath load floor).
- Drain contaminated fuel with a fuel cart into approved containers; label waste for hazardous waste consignment where required.
- Renew fuel filters and inspect pump unit seals.
- Refill with correct UK fuel grade; prime low-pressure feed.
- Clear DTCs, check for leaks, road test.

Frequently asked questions
What should I do if I put petrol in my Land Rover Discovery Sport diesel?
Do not start the engine. Petrol in diesel destroys HPFP lubrication on common-rail TDIs. Call a GBIFDA-certified technician to extract fuel from the tank via the OEM access method and dispose of waste fuel legally.
Can I drive my Discovery Sport to the garage after misfuelling?
No — even a few hundred metres can draw petrol into the high-pressure system. Recovery without starting is the safest option.
Where is the AdBlue filler on diesel Discovery Sport?
AdBlue is separate from diesel — blue cap, smaller neck. Never add fuel to the AdBlue tank; contamination requires specialist cleaning per TOPIx.
