2004 BMW 6 SERIES COUPE catalytic converter

Corrosion Protection
Extensive corrosion protection measures
implemented by BMW now make it possible
to offer a six-year limited anti-corrosion
warranty against rust perforation on your
vehicle provided that the vehicle is maintained
in accordance with the provisions of the New
Vehicle Limited Warranty as outlined in the
Warranty Section of this Statement (page 30).
The major degree of corrosion protection is
due to the electrophoretic dip painting
process which cathodically deposits paint
particles on all body parts, attracting paint
particles into the minutest cavities or seams.
Body parts are designed to provide optimum
corrosion protection.
During manufacture, exterior body parts
receive an additional corrosion protection
coat. Hood, trunk, doors and other body
parts are coated with PVC and sealed from
the outside.
All floor panels receive a resilient coating of
PVC for maximum protection against damage
due to stones, etc.
Corrosion protection materials tested over
many years are applied to the surfaces of
cavities and to the entire underside of the
vehicle during and after assembly.
Requirements for maintaining the six-year
limited anti-corrosion warranty are outlined in
the Warranty Section of this Statement (page
32).
Restoring corrosion protection
Please take care that anti-corrosion material
is replaced when your car is repaired after
body or chassis damage.
BMW will not accept any liability for any
parts and accessories not approved by
BMW.
Underbody maintenance
The underbody has to be cleaned at least
once a year, in spring, with plain water in
order to remove mud, chemical sediments
and other deposits. If those materials are not
removed, corrosion (rust) will occur on metal
components.
Your BMW center will do this anti-corrosion
service for you.
WARNING
Do not apply additional undercoating or rust-
proofing on or near the exhaust manifold,
exhaust pipes, catalytic converter or heat
shields. During driving, the substance used
for undercoating could overheat and cause a
fire.
