OEM access procedure
- Secure the vehicle with ignition OFF; do not start the engine if the wrong fuel was added.
- Confirm contamination type and whether the engine was cranked or driven.
- Relieve fuel system pressure per the OEM workshop manual.
- Disconnect the 12 V negative battery terminal; hybrid, PHEV, and EV models require OEM high-voltage disable first.
- Access the tank via the OEM fuel pump access panel or by lowering the tank per the workshop manual.
- Drain contaminated fuel into approved containers; dispose via a licensed collector under HSNO Act 1996 and regional council rules.
- Replace the fuel filter and inspect lines; flush if the engine ran on contaminated fuel.
- Refill with correct NZ fuel (91/95/98 petrol, diesel, or AdBlue only in the AdBlue tank), prime, leak-check, and test per OEM.
Additional notes
- Japanese import — verify fuel grade labels and chassis code before drain
Frequently asked questions
Was the Koleos sold new in New Zealand?
Usually encountered as a used Japanese import. Remediation still follows the manufacturer workshop manual for that model.
What if I put the wrong fuel in at the forecourt?
Do not start the engine if possible. NZIFDA certified technicians drain via OEM pump or tank procedures, not filler-neck siphoning.
Who pays for misfuel repair in NZ?
Typically the vehicle owner or insurer. Consumer Guarantees Act and Fair Trading Act do not treat driver misfuelling as a vehicle defect.
