Fuel and exhaust gas cleaning
●
When changing or adding engine oil, do not
exceed the necessary amount ›››page294,
Checking and topping up the engine oil
level.
●
Never tow the vehicle to start it, use jump
leads if necessary ›››page274.
If you should notice misring, uneven running
or loss of power when the car is moving, have
the vehicle inspected by a specialised work-
shop. In general, the emissions warning lamp
will light up when any of these symptoms
occur. If this happens, any unburnt fuel can
enter the exhaust system and escape into the
atmosphere. The catalytic converter can also
be damaged by overheating.
NOTICE
Never run the fuel tank completely dry be-
cause an irregular fuel supply can cause igni-
tion faults. This allows unburnt fuel to enter
the exhaust system, which could cause over-
heating and damage the catalytic converter.
For the sake of the environment
Even when the emission control system is
working perfectly, there may be a smell of
sulphur from the gases on occasions. This
depends on the sulphur content of the fuel
used. This can quite often be avoided by
changing to another brand of fuel.
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 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270.
●
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.
