Irregular engine running and faults
Irregular engine running or faults when driving may be a sign of poor fuel quality.
1. Reduce speed immediately.
2. Drive to the nearest suitably qualified workshop at medium engine speeds and low loads on the engine. Volkswagen
recommends using an authorised Volkswagen repairer.
3. If these symptoms occur immediately after refuelling, switch off the engine immediately to avoid any subsequent damage.
4.
Seek expert assistance.
Particulate filter clogged with soot
The indicator lamp lights up yellow.
The particulate filter is saturated with soot and requires regeneration.
Prerequisite for regeneration trip: the engine is at operating temperature.
For petrol engines
1.0 l to 1.8 l
1. Drive at a speed between around 50 km/h and 120 km/h (around 30 mph and 75 mph).
The achieved temperature increase can burn the soot off the filter.
2. End the regeneration drive only when the indicator lamp goes out.
3. Go to a suitably qualified workshop without delay if the indicator lamp continues to light up after driving for approximately
40 minutes. Volkswagen recommends using an authorised Volkswagen repairer.
2.0 l and 3.0 l
1. Drive at a speed of at least 80 km/h (around 50 mph).
2. To allow the vehicle to coast while a gear is engaged, take your foot off the accelerator completely for a few seconds.
3. Repeat this procedure (accelerate and coast) until the indicator lamp goes out.
4. If the indicator lamp does not go out after some time, go immediately to a suitably qualified workshop. Volkswagen recommends
using an authorised Volkswagen repairer.
For diesel engines
1. Drive at a speed between around 50 km/h and 120 km/h (around 30 mph and 75 mph).
The achieved temperature increase can burn the soot off the filter.
2. End the regeneration drive only when the indicator lamp goes out.
3. Go to a suitably qualified workshop without delay if the indicator lamp continues to light up after driving for approximately
40 minutes. Volkswagen recommends using an authorised Volkswagen repairer.
If a message requesting you to refuel appears additionally on the instrument cluster display during the regeneration drive, the
regeneration process of the particulate filter could be interrupted.
1. Refuel if necessary and then continue the regeneration drive.
Emissions-relevant fault
The indicator lamp lights up yellow.
Fault in an emissions-relevant component that can damage the vehicle.
