For your convenience, you may also wish to have
your BMW center perform any necessary
operations to fulfill any state inspection
requirements in your area, concurrent with the
maintenance services specified above during
other repairs. Should you request more
frequent maintenance service, the cost of
these services will not be covered by the

computing of the optimum maintenance interval
for your type of operations and driving style. Your
BMW center has made a substantial investment
in unique BMW special service tools to enable
BMW factory trained service technicians to
perform quality repairs on your BMW in minimal

Quality Certification I
For a detailed list of items inspected, refer to the
Quality Certification I form provided to the Owner
at time of delivery. A copy of the form is on file at
the selling BMW center.
Fuel Quality – Gasoline
Only use fuels advertised to have adequate
detergency and low alcohol (such as ethanol)
content. Please refer to your owner’s manual for
important information on the fuel recommended
for use in your vehicle. 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 recommend a gasoline additive that will
