⚠️ Citroën C3 — Low misfuel risk
NZ C3 retail line is largely petrol; misfuel risk is lower than diesel vans but HPFP damage still possible if diesel is added.
If the engine was not started
Do not start the engine; drain and flush; replace fuel filter.
If the engine was started
Drain tank, replace filters, inspect high-pressure pump and injectors; diesel SCR faults may need diagnosis after contamination.
⚠️ Citroën position — C3
Stellantis prescribes pump-module access for drainage where fitted; running on wrong fuel is misuse and not warranty-covered. Follow ePER / Tech Authority procedures.

Frequently asked questions
I misfuelled my Citroën C3 — can I drive to a garage?
No — towing without starting is safer. NZIFDA-certified drainage reduces repair cost.
Will Stellantis honour warranty after misfuel?
Fuel contamination damage is excluded; keep drainage records for insurer claims.
Who can drain the tank legally in New Zealand?
Use a NZIFDA-certified operator and a licensed waste carrier for contaminated fuel (Waste Minimisation Act 2008 and regional council requirements under the Resource Management Act 1991).
