Please note the information on the inside of the fuel tank flap.
The use of sulphur-free diesel to EN 590 (in Germany: EN 590 or DIN 51628) is recommended. If that type of fuel is unavailable, diesel to EN 590 can be used. It must have a cetane number (CN) of at least 51. The cetane number indicates the ignition quality of the diesel fuel.
Winter-grade diesel
Diesel fuel can thicken in winter. For this reason petrol stations in some countries also offer winter diesel.
Caution!
  • The vehicle is not designed for the use of biodiesel (FAME fuel). The fuel system would be damaged if you used biodiesel.
  • Do not mix fuel additives ("thinners", petrol or similar additives) with the diesel fuel.
  • If poor-quality diesel fuel is used, it may be necessary to drain the water separator on the fuel filter more frequently than is specified in the Service Schedule. We recommend having this done by a specialist workshop. If water is allowed to collect in the filter, this can cause engine performance problems.
