The tubing system for the tank breather at the
filler pipe has been considerably simplified as
compared to the predecessor model. With the
exception of diesel vehicles, the pipe
connections have been converted to quick-
release couplings.
A new feature is the use of a 2-stage delivery
pump for each tank chamber in
separate reservoirs.
The fuel level is measured by two immersion
tube senders combined with two angle
senders.

Fuel tank
The fuel tank capacity is approximately
90 litres.
The basic unit consists of two plasma-welded
stainless steel shells. There are no differences
between petrol and diesel engine versions.
The filler neck is a single piece and welded to
the basic unit. For reasons of crash safety, the
centre section of the filler neck takes the form
of a corrugated tube.
In crash situations, this section is subject to
defined deformation to prevent cracks and
fuel spillage.
To create the best possible ergonomic
conditions for the rear passengers in
combination with maximum luggage
compartment volume, the two tank
compartments are shallower than in the
predecessor model.
The additional expansion tank has been taken
out of the filler pipe and moved to the fuel
tank.
The switch from plastic to stainless steel
was necessary for compliance with
American LEV II legislation, which
demands a further significant reduction in
permissible emission levels.
