If you mix diesel fuel with petrol, the flash point of the fuel mixture is lower than that of pure diesel fuel.
Even small amounts of the wrong fuel could result in damage to the fuel system, the engine and the emission control system.
In countries without sulphur-free diesel fuel, refuel using only low-sulphur diesel fuel with a sulphur content less than 50 ppm.

marine diesel

If you have accidentally refuelled with the wrong fuel:
The following compatibility indication for fuel applies to your vehicle:
on the vehicle on the information label in the fuel filler flap More
on the fuel pump or pump nozzle suitable for your vehicle throughout Europe
Refuel your vehicle with as much winter diesel fuel as possible at the beginning of winter.
Before changing over to winter diesel fuel, the fuel tank should be empty, if possible. When first refuelling with winter diesel fuel, only refuel using a small amount, e.g. to reserve level. The fuel tank can be filled as usual when next refuelling.
Further information on fuel can be obtained at a filling station or a qualified specialist workshop.
