    Procedure for removal of the particulate filter extends in cars of any brand very similar. Upon arrival to the Authorised Workshop ADS diagnosticians our subject car diagnostic procedure particulate filter and interpret other engine parameters that may indicate the cause of failure of the filter. When the cause of failure is determined, the filter housing is cut, the contribution of particulate filter removed, and then the can is welded closed and protects the weld corrosion. In some models the filter cartridge is removed without cutting the can. NOTE! If the car is a catalyst it is not removed, you do not change the pressure / resistance exhaust system. Then electrician mounts emulator particulate filter performs diagnostics / write errors. Test drive and the car is repaired.

Causes of failure of the particulate filter

The reasons for failure of the filter can be many, but usually does not damage the filter itself is just like that. The most common causes are:

Driving with low engine speeds and under low load

This vehicle operation can not be achieved through the exhaust temperature sufficient to carry out self-cleaning filter (ie regeneration). Consequently, the particulate filter is clogged.

Failure of the intake

Air intake system or the engine components to the combustion chamber the air fuel mixture enters the air. This system turbocharged engines operated at a pressure that generates turbocharger, further enhances this defect rate components of the system. The reason for clogging of the particulate filter is too large amount of particulate matter in the exhaust gas, which may be caused by too small amount of oxygen necessary for the complete combustion of air fuel mixture in the combustion chamber. Too rich (fuel) to a completely mix is ??not burned in the exhaust gas so that there is a large amount of particulate matter. For vehicles not equipped with a particulate filter is a phenomenon manifested as a characteristic cloud of smoke is often seen when moving off.

Too low amount of oxygen in the air-fuel mixture can be caused by:

- Ie the gaping leak intercooler, intake hoses, intake manifold, EGR valve, etc.

- Malfunction of the system, ie fault the exhaust gas recirculation, vortex flaps, throttle, etc.

- Failure of the turbo - low productivity

Awaria układu wtryskowego

Układ wtryskowy czyli układ, który dostarcza do komory spalania olej napędowy. Mieszanka paliwowo powietrzna nie ulegnie zupełnemu spaleniu również kiedy do komory spalanie dostarczymy zbyt duża ilość paliwa. Zbyt duża dawka może być spowodowana awariami:

wtryskiwacz paliwa stosowany w samochodach z silnikiem diesla czujnik ciśnienia paliwa pompa wysokiego ciśnienia


- wtryskiwacza/wtryskiwaczy – tzw. lejący wtrysk, czyli podający w pewnych warunkach pracy zbyt obfitą dawkę paliwa.

- czujnika ciśnienia paliwa

- pompy wysokiego ciśnienia itp.

Inne usterki

Nasi diagności dość często spotykają się z awariami samego osprzętu filtra cząstek stałych, czyli elementów decydujących o weryfikacji przez sterownik silnika kondycji filtra. Do tych elementów możemy zaliczyć:

- czujniki temperatury na filtrze cząstek stałych

- czujnik ciśnienia różnicowego

- gumowe wężyki łączące czujnik różnicowy z filtrem cząstek stałych.
