Frequently asked questions
What should I do if I put the wrong fuel in my MINI Hardtop?
Do not start the engine or cycle the ignition to RUN if the fuel pump may prime. Have the vehicle recovered to a USIFDA Certified Repair Facility and follow MINI service information for tank draining and fuel system inspection.
Does MINI warranty cover misfuel damage on a Hardtop?
No. MINI warranties exclude damage from improper or contaminated fuel. Repairs are typically customer-pay; document the OEM-prescribed remediation procedure.
Can fuel be removed from a Hardtop through the filler neck?
MINI documents fuel recovery via the fuel pump module access and/or tank removal using approved equipment—not filler-neck siphoning. Follow ISTA/TIS or erWin procedures for your model year.
