Mercedes-Benz manufacturer position
Mercedes-Benz is a core premium brand in New Zealand with passenger cars, SUVs, and Vito/Sprinter commercial vans. Petrol, diesel, mild hybrid, and EQ battery electric models coexist in the NZ fleet. WIS documents fuel pump access and tank removal; fuel contamination is warranty-excluded misuse.
Fuel system notes
- AdBlue on diesel — separate filler from diesel neck.
- 48 V mild-hybrid — follow WIS battery disconnect before fuel work.
- EQ models have no petrol tank — fluid contamination only.

Frequently asked questions
What should I do if I put the wrong fuel in my Mercedes-Benz?
Do not start the engine or turn the ignition on if the lift pump may prime. Arrange recovery to an NZIFDA certified technician and follow OEM service information for tank draining and inspection.
Does Mercedes-Benz warranty cover misfuel damage in New Zealand?
No. Fuel contamination is treated as misuse and is excluded under the Consumer Guarantees Act 1993 manufacturer remedies. Keep drainage invoices for insurance or Motor Vehicle Disputes Tribunal records.
Can fuel be siphoned from the filler neck on a Mercedes-Benz?
OEM service information documents recovery via the fuel pump module and/or tank removal with approved equipment — not filler-neck siphoning. NZIFDA certified work follows those procedures.
