Seat Yellow Warning Lights - Particulate Filter Clogged Warning Light
The indicator lamp lights up yellow.
The particulate filter eliminates most of the soot from the exhaust gas system. Under normal driving conditions the filter cleans itself. If the filter does not clean itself (e.g. if short journeys are made continuously), it becomes blocked with soot and the following indication is displayed to the driver:
Particulate filter: cleaned while the vehicle is moving. See Manual.
The particulate filter needs cleaning (regeneration).
Regeneration of the petrol and diesel particulate filter
Requirements for the regeneration journey: the engine is at operating temperature.
- Drive at a speed of between 50-120 km/h (31-75 mph). This increases the temperature and burns the soot in the filter.
- Consider the legal speed limits as well as the recommended gears.
- End the regeneration journey once the control warning lamp has gone out.
If the warning lamp stays on after 30 minutes of running in regeneration mode, have a specialised workshop repair the fault.
Regeneration of the particulate filter (only for 2.0l and 2.5l TSI engines)
Requirements for the regeneration journey: the engine is at operating temperature.
- Drive at a speed of at least 80 km/h.
- Completely remove your foot from the accelerator pedal for a few seconds to let the vehicle roll with the gear engaged.
- Consider the legal speed limits as well as the recommended gears.
- Repeat this procedure (accelerate and let roll) until the control lamp turns off.
This procedure involves an autonomous particulate filter cleaning process and may take some time. If the warning lamp does not turn off, go immediately to a specialised workshop to repair the fault.
