Saptamana aceasta am avut si eu ceva probleme cu DPF-ul.Dupa mai multe incercari esuate de curatare ,regenerarea nu sa mai putut face si am fost nevoit sa apelez la eliminarea acestuia .
Stie careva care sunt performantele masinii dupa aceasta operatiune,consum etc ?
Mentionez ca detin un opel astra h 1.3.

Vreau neaparat sa va spun ce am patit la service-ul unde am fost sa imi anulez DPF-ul ,si astept niste pareri din partea voastra.
Problema masinii de la bun inceput : DPF infundat si solutia era anulare, bineinteles atat din soft cat si fizic.Dupa ce au terminat treaba am fost in proba cu masina care inca imi vedea filtrul acolo,ca si cand softul nu a fost bine instalat.Dupa aproximativ 4 -5 zile de teste cel ce o facut resoftarea isi da seama ca mecanicul a scos defapt catalizatorul.
Ce credeti ,pot avea probleme la itp ?Ce alte probleme mai pot avea acum?
Ma gandesc sa le cer banii pe catalizator deoarece nu vreau sa mai las masina acolo .
Merci

Eu in urma cu 3 ani am facut DPF off. Odata cu filtrul de particule a fost eliminat si catalizatorul, deoarece era rupt in bucati. Cel ce a facut operatiunea mi a spus ca nu voi avea probleme nici la ITP, daca motorul functioneaza corect si voi alimenta doar cu motorina aditivata, iar inainte de verificare voi scoate masina la drum intins si-i voi da blana in treptele 2-4, ca sa sufle funinginea din admisie. Am mers pe mana lui, de atunci circul cu teava goala si in plus am blindat si EGR ul ! Rezultatul> am trecut ITP ul cu brio!

Niste informatii utile pentru posesorii de DePeFeu:
Question 1: Has the ECU supplied black box data to give information on
the last regeneration or regeneration sequence?
Answer: All applications show the current loading status in percent,
and the distance covered since the last regeneration or regeneration
attempt. TECH 2 gives no information on whether the previous
regeneration (or regenerations) were complete and successful.
Question 2: The glow plug symbol is flashing. Why? What should be
done?
Answer: The DPF regeneration has not been completed during normal
driving and has now reached its maximum saturation at which it can
still be regenerated. The limit value depends on variant and MY, but
is in the range of 105% - 125%.
Possible causes for this are:
a.) Frequent short distance journeys, i.e. high soot loading while at
the same time regeneration of the DPF does not take place because
the conditions necessary were not fulfilled.
b.) Frequent interrupted regenerations, i.e. the engine was switched
off during regeneration. Applies to short journey drivers who have
at least fulfilled the conditions for triggering regeneration.
If the glow plug light flashes, the vehicle should be driven
until it goes out.
Important: Regeneration is carried out more often (2 - 3 times) during
the first 1000 km of driving in order to achieve a defined
loading status of the DPF. This is necessary to reduce
component and system tolerances, and forms the basis for
precise calculation of the soot loading in the DPF.
Question 3: What conditions are required for the DPF to begin
regeneration?
Answer: The following conditions must be fulfilled for regeneration to
begin.
a.) Engine running since start > 2 minutes.
b.) Calculated saturation > 80%.
c.) Coolant temperature > 70°C for at least 2 minutes.
d.) No DPF-relevant faults stored in system.
e.) A defined vehicle speed threshold must be exceeded in some cases
(e.g. for 80%-100% loading, one time 100 km/h), at loadings above
100% the speed does not matter.
Question 4: After service regeneration, TECH2 data list shows a
current loading status of 70% or 78%. Why?
Answer: The regeneration intensity of the static regeneration is not
as effective as that of dynamic regeneration. The value is therefore
set to 70% - 78% loading so that the ECU then triggers a dynamic
regeneration when the required conditions (see question 3) are
fulfilled.
Exception: Vehicles equipped with 1,7 liter Diesel engine will show
a saturation level of 32% after service regeneration.
Question 5: Under what conditions is regeneration interrupted/ended
once it has started?
Answer: Normally when regeneration has been successfully completed,
or:
a.) After a maximum regeneration time (20 - 25 min.).
b.) If the engine is switched off or has stalled.
c.) If the engine is left idling for a long time (5 - 10 min.).
d.) If 1000°C is detected by the exhaust temperature sensor.
e.) If during regeneration, a fault is detected on the components
relevant for combustion (injection/intake system).
If a regeneration is interrupted once started but before it has been
50% completed, the glow plug lamp flashes on the next engine start
(cold or hot) and regeneration begins again once the operating
conditions (see 3) have been fulfilled.
Question 6: The DPF loading is (far) below the threshold value for the
flashing glow plug lamp, but the customer comes in with
the SVS light on and the DPF clogged. Why?
Answer: In this case, there is very likely a hardware fault or tuning.
This fault is usually due to a leak in the air-carrying parts. Often
there is a split in one of the charge air hoses or charge air cooler.
Due to the leak, which the ECU or loading model does not detect, the
engine will emit more smoke if the pressure difference remains below
a defined threshold. The increased smoke emission can clog the DPF.
Furthermore, a disproportionately high loading of the DPF can be due
to a (partly) open EGR valve.
A tuned engine emits more smoke than calculated in the soot loading
model. This may result in a clogged DPF without any customer
notification.
In general please check the field remedy database for known fault
pictures and diagnosis instructions.
Question 7: How long does complete regeneration take?
a.) In the most favourable case?
b.) In the least favourable case?
Answer: a.) Under constant conditions, i.e. the exhaust temperature
necessary for regeneration always lies above the required value, for
example during motorway/cross-country driving, the average
regeneration time is 10 minutes.
b.) Vehicle conditions such as long down-hill descents, frequent
driving in the low-load range (city driving, idling) allow the exhaust
temperature to fall. If the conditions for triggering regeneration
were fulfilled, the active regeneration time can be extended up to
25 minutes (depending on engine type). If complete regeneration is
not possible within this period, the regeneration will be interrupted.
Question 8: How does regeneration affect the oil life?
Answer: On each regeneration or attempted regeneration, a certain
diesel fuel amount is injected into the engine oil which reduces the
oil life. If the "INSP" light in the instrument cluster comes on, the
engine oil is exhausted and must be changed. Failure to do so could
damage the engine.
Question 9: Is the DPF sensor important for the regeneration
procedure?
Answer: The sensor does not initiate the regeneration, which is based
on a model. The DPF sensor fulfils purely a diagnostic function to
monitor the counter-pressure in the DPF.
Exceptions are the Antara, Captiva, Z20DTx; on these models, the DPF
sensor is involved in triggering the regeneration.
Question 10: How does the Soot loading value in ECU behave?
a.) After SPS programming.
b.) After a change of ECU.
c.) After disconnecting the battery.
a.) After a pure SPS, the loading status is retained. On a change of
ECU or reprogramming of the existing ECU, after reset the loading
status jumps to 104% (e.g. on the Z19DTx), and then regeneration takes
place. Variations are possible depending on model year or application.
b.) The current soot loading value will be stored on Tech 2 flashcard
prior ECU removal. This value will be programmed into new Service ECU
via ECU reprogramming.
c.) No effect.
Question 1: Has the ECU supplied black box data to give information on
