Diesel particulate filter

Applies to: vehicles with diesel engine and diesel particulate filter

To support the filter's self-cleaning function:

Drive for approximately 15 minutes at 37 mph (60 km/h) or above in the S selector lever position.

Keep the engine speed around 2,000 RPM.

The temperature increase that will result from this can burn off the soot in the filter. The indicator light will turn off when the cleaning has completed successfully.

If the indicator light does not turn off, drive immediately to an authorized Audi dealer or authorized Audi Service Facility to have the malfunction corrected.

WARNING

Always adapt your speed to the current weather, road and traffic conditions. You should never disobey traffic laws in order to follow driving recommendations.
