Cupra FORMENTOR 2024 - Particulate Filter

Fuel and exhaust gas cleaning
327
Engine management and emissions control system
1)
Except 2.0l TSI petrol engines.
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
Valid for: vehicles with petrol or diesel particu-
late lters
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 lter: cleaned while the vehi-
cle 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 50-120 km/h
(31-75mph). This increases the temperature
and burns the soot in the lter ›››page327.
●
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 TSI petrol engines)
Requirements for the regeneration journey:
the engine is at operating temperature.
●
Drive at a speed of at least 80 km/h
›››page327.
●
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.
Note
If during the particulate lter regeneration
process you also get a fuel reserve warning ,
the process may be interrupted. Refuel and
continue with the particulate lter regenera-
tion process.
