Kia Sportage II 2.0 CRDI 103kw 2008: DPF Blocked, Particle Filter Malfunction, High Pressure

Hello, Kia Sportage II 2.0 CRDI 103kw. 2008. Check has been flashing in the car for several years and the error "particle filter malfunction" appears. Currently, accelerating slightly begins to scrape up the engine.
SPECIFICATIONS:

- particle filter pressure 1027hPa (much too much)
-fumes pressure difference 0hPa (too little)
- exhaust gas mass flow 30m3 / h (standard)

Adding gas at idle or driving a car is changing only flue gas mass flow up to about 200 m3 / h. Nothing happens with the difference in exhaust pressure even if I unplug the wires from the sensor (at the dpf input it blows strongly, at the output it blows very weakly) but the sensor does not register at all. The pressure of the particulate filter is constantly 1027hPa - how is it measured? is the calculated value?

The exhaust only has a lambda probe, temperature sensor before turbo / dpf, exhaust pressure difference sensor and a sensor in the middle of the dpf.

What to do with it?

When I dismantled the DPF and started the engine, all the time the parameters were:

- particle filter pressure 1027hPa (much too much)
-fumes pressure difference 0hPa (too little)
- exhaust gas mass flow 30m3 / h (standard)

And how is the exhaust mass flow calculated ?? probe

Sometimes someone no longer fumbled in the software?

Unfortunately, I do not know, the customer was reportedly in the ASO about 3 years ago and apparently they did it to him and before he got home it again lit a check and he drove like that. Yesterday, while driving in a traffic jam, he stopped responding to the accelerator pedal. I took out the DPF and after the initial inspection it seems to be all and rather not clogged up, come looking at the sun you can't see the passage ... [/ table]

The filter is not a catalyst to pass. Read how it works ...

I replaced the exhaust pressure difference sensor with a new original and nothing has changed ... after driving, it returns an error alternately of either this sensor or the lambda probe. Wires from dpf to the sensor are definitely unobstructed and not punctured.

So somebody failed to program the filter from the ECU. You would have to get the original map and upload or substitute the ECU.

Regarding the exhaust pressure difference sensor, I checked it with a meter and it is ok, i.e. after starting the engine it is about 1V and as the gas is added it increases linearly to about 2V. I also noticed that on a cold engine when I start and the engine tugs, the EGR opens at that time, then catches the DPF error and turns off the EGR and does not tug anymore. What's up?

Egr not jam?

Today I replaced the EGR, it stopped pulling but a probe error occurred. Then I replaced the probe and a regeneration error occurred. Then I did the regeneration at a standstill and there are no fault codes for now, but I'm only worried about reading the current parameters, i.e. the exhaust pressure is still too high. Tester is cheating on me?

Filter clogged, exhaust gas back pressure too high, boiling EGR.

What do you diagnose?

gutmann 66, but on carmanscann showed the same errors and parameters

In my Carens III 2CRDI 140KM 2009 "check" flashed, flickered and went out, so it lasted all summer, in winter it began to flash all the time. The computer showed an error - DPF blocked, according to the DPF service for replacement. Now it is rather fear to cut it, because it is not known how it will be on the review, and the review in July.
In addition, it bothered me that, despite the clogged DPF, my car still had power and was rather snappy, so I took matters into my own hands. I disconnected the DPF differential pressure sensor from the tubing to see how it blows. After all, if the filter is clogged, it should blow at least from the one in front of the filter. From both hoses it was blowing, but rather weakly, and from it before the filter it was even weaker than from that one. I checked if one is damaged. They were not, so I pushed them with a bicycle rope and washed with EGR cleaning fluid. After this operation, it blew evenly and both harder.
This hose before the filter was clearly clogged, because the line had to be pushed hard enough before it was unblocked.

I have assembled everything and deleted the "check engine" control and have been calm for a month.
We'll see what happens next.
