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.

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, per-

haps while regular maintenance is performed.

Your BMW center can also recommend a gaso-

line additive that will provide sufficient deter-

gency. 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.
