Technical Service Bulletin
Technical Background
Actuation of a pressure relief valve inside the in-line fuel filter
can cause a tapping sound audible inside the passenger
compartment. The valve actuates when fuel demand decreases,
for example when quickly lifting off the throttle pedal.
The in-line fuel filter is secured in a bracket which is mounted on
a structural member at the left rear of the vehicle, behind the
driver’s seat (Figure 1). Normal operating sound of the filter can
be transmitted to the passenger compartment.

Figure 1. In-line fuel filter.

Production Solution
An acoustically optimized fuel filter has been implemented in production.
