BMW Z4 Roadster 3.0i 2005 - Manual (Page 8)

Unscheduled Maintenance
Only use fuels advertised to have adequate
detergency and low alcohol content. Use of
fuels with insufficient detergent and/or excess
alcohol can cause driveability problems that
necessitate cleaning intake valves and fuel
injection valves, and, when applicable,
adjusting the engine idle. We suggest having
this work performed by your authorized BMW
center, perhaps while regular maintenance is
performed. Your BMW center can also recom-
mend a gasoline additive that will provide
sufficient detergency. While this recommended
unscheduled maintenance is not required in
order to maintain the emission warranty,
cleaning of intake valves or, when applicable,
fuel injection valves, or adjustment of engine
idle, necessitated by use of inappropriate fuel,
is not covered by warranty because no defect
in material or workmanship or component
failure is involved.
Special Note
Maintenance items and schedules stated
herein reflect the combined recommendations
for all model 2005 BMW Z4, and are subject to
change. The most current maintenance
recommendations are available from your
authorized BMW center.
