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.
