WARNING
Hot vehicle parts and exhaust can ignite flammable or explosive materials in the vicinity. This can lead to a fire and cause accidents and serious or fatal injuries.
Never park the vehicle in such a way that parts of the exhaust system come into contact with flammable materials under the vehicle, such as dry grass.
Never use additional underbody protection or corrosion protection on exhaust pipes, catalytic converters, particulate filters or heat shields.
Catalytic converter
Please read the introductory information and heed the Warnings and Notice ⇒
and
Safety precautions for handling fuel.
To ensure that the exhaust system and the engine catalytic converter can work correctly for a long time, observe the following:
Only refuel with fuel permitted for the vehicle.
Never drive until the fuel tank is completely empty ⇒ Refueling.
Never add too much engine oil ⇒ Checking the engine oil level and adding oil .
Do not tow-start the vehicle; use jump-start assistance instead ⇒ Preparing and Performing a Jump-start.
If there are engine misfires, loss of power, or poor engine operation while driving, reduce the speed immediately and have the vehicle checked by suitably qualified
professionals ⇒ Troubleshooting. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility. Otherwise,
uncombusted fuel could be present in the exhaust system and then enter the atmosphere. The catalytic converter may also be damaged from overheating.
The exhaust may smell like sulfur when the emissions control system is running correctly.
Particulate filter
Please read the introductory information and heed the Warnings and Notice ⇒
and
Safety precautions for handling fuel.
Function
The particulate filter (depends on how your vehicle is equipped) filters out soot from the exhaust gas.
Regeneration
With normal vehicle usage, the filter cleans itself. If the filter is unable to clean itself, e.g. if you only make short trips for an extended period of time, the filter can
become blocked with soot. The particulate filter needs to be cleaned (regenerated).
Noises, light odors, and increased engine speeds may occur during the regeneration. The radiator fan may continue to run while driving and after turning off the
engine.
To assist in particulate filter regeneration, Volkswagen recommends avoiding driving short distances too frequently.
The soot in the particulate filter is burned periodically at high temperatures. The yellow
indicator light does not turn on during a periodic regeneration.
Safety precautions for handling fuel.
Troubleshooting
Please read the introductory information and heed the Warnings and Notice ⇒
and
If the engine does not run smoothly and malfunctions
If the engine does not run smoothly or malfunctions while driving, it can indicate poor fuel quality.
1. Reduce your speed immediately.
2. Drive with a moderate RPM and low engine load to the nearest suitably qualified professional. Volkswagen recommends contacting an authorized Volkswagen
dealer or authorized Volkswagen Service Facility.
3. If these symptoms occur directly after refueling, stop the engine immediately to prevent subsequent damage.
4.
Do not continue driving! Contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance.
Particulate filter clogged with soot
The yellow indicator light turns on.
The particulate filter is clogged with soot and a regeneration is necessary.
Prerequisite for the regeneration drive: The engine is at operating temperature.
For gasoline engines
1.0 l to 1.8 l
1. Drive at a speed of between 50 km/h and 120 km/h (30 mph and 75 mph).
The resulting temperature increase burns off the soot in the filter.
2. Only end the regeneration drive once the indicator light turns off.
3. If the indicator light is still illuminated after driving for approximately 40 minutes, drive immediately to suitably qualified professionals for assistance. Volkswagen
