Diesel

Fuel system

Diesel engines are sensitive to contaminants.
Only use diesel from a well-known oil
company. Never fill up with diesel if the
quality is dubious. The large oil companies
also produce a special winter-grade diesel
for temperatures around freezing. This fuel is
less viscous at low temperatures and
reduces the risk of wax forming in the fuel
system.
The risk of condensation in the fuel tank is
reduced if the tank is kept well filled. When
refuelling, check that the area around the fuel
filler pipe is clean. Avoid spilling fuel onto the
paintwork. Wash off any spillage with
detergent and water.
Empty tank
No special procedures are required if the
tank runs dry.
RME (Rape Methyl Ester)
A maximum of 5 % RME may be mixed with
the diesel.
Important!
There is a risk of engine damage if the
RME concentration is greater than 5 %.
Draining condensation from the

fuel filter

The fuel filter separates condensation from
the fuel. Condensation can disrupt engine
operation.
The fuel filter must be drained at the intervals
specified in the Service and Warranty
Booklet or if you suspect that the car has
been filled with contaminated fuel.
