Fuel and exhaust gas cleaning

Engine management and emissions control system

Except 2.0l and 2.5l TSI petrol engines.
Particulate lter
The particulate lter eliminates most of the
soot from the exhaust gas system. Under nor-
mal driving conditions the lter cleans itself.
If the lter 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 lter needs cleaning (regener-
ation).
Regeneration of the petrol and diesel partic-
ulate lter
1)
Requirements for the regeneration journey:
the engine is at operating temperature.
●
Drive at a speed of between 50120 km/h
(31-75mph). This increases the temperature
and burns the soot in the lter ›››page301.
●
Consider the legal speed limits as well as the
recommended gears.
●
End the regeneration journey once the con-
trol warning lamp has gone out.
If the warning lamp stays on after 30 minutes
of running in regeneration mode, have a speci-
alised workshop repair the fault.
Regeneration of the particulate
lter (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
›››page301.
●
Completely remove your foot from the ac-
celerator 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 o.
This procedure involves an autonomous par-
ticulate lter cleaning process and may take
some time.
If the warning lamp does not turn o, go im-
mediately to a specialised workshop to repair
the fault.
WARNING
Always adjust your speed to suit the weather
conditions, roads, braking distance and traf-
c if the particulate lter is in its regenera-
tion phase. Route recommendations should
never make you disregard each country's
specic traic regulations.
NOTICE
●
When the exhaust system detects that the
particulate lter is close to saturation, the
self-cleaning function of this system recom-
mends optimal driving for this function.
●
Due to the high temperatures caused by
the regeneration of the particulate lter, it is
possible that the radiator fan will activate af-
ter stopping the engine, even it its operating
temperature has not been reached.
●
Noise, smells and high idle speeds can oc-
cur during regeneration.
●
Always use the correct engine oil and the
correct fuel to make sure the useful life of
the particulate lter is not aected. Also
avoid making short trips all the time.
Troubleshooting
Fault in the emissions control system
The indicator lamp lights up yellow.
Reduce speed and drive carefully to the near-
est specialised workshop to have the engine
checked.
Combustion failures that could damage
the catalytic converter
The control lamp ashes yellow.
