Audi Q7: Emissions control
system
General information
WARNING
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exhaust tail pipes once they
have become hot. This could result in burns.
- Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the emissions system
could start a fire.
- Do not apply underbody protectant in the
exhaust system area, because this increases
the risk of fire.
Catalytic converter
Observe the safety precautions General
information.
The vehicle may only be driven with unleaded
gasoline, or the catalytic converter will be destroyed.
Never drive until the tank is completely empty.
The irregular supply of fuel that results from that
can cause engine misfires. Uncombusted fuel
could enter the exhaust system, which could
cause overheating and damage to the catalytic
converter.
Malfunction Indicator Lamp (MIL)
If the
indicator light blinks
or turns on, there
is a malfunction that is causing poor emissions
quality and that could damage the catalytic converter.
Drive slowly to an authorized Audi dealer
or authorized Audi Service Facility to have the
malfunction corrected.
The indicator light can also turn on if the fuel filler
cap is not closed correctly.
