Chevrolet Captiva 2.0 vcdi (2007): DPF Burns Every 60km After New Replacement

Hello to all forum users!

And so !

I have a problem with frequent burning of DPF, the topic has already been edited here in the forum, but!
A year ago I bought a Captiva from 2007 2.0 Vcdi, after some time I noticed that the engine goes at 1000 revs, the fans turn on and it smells like grilled I read a bit here on the forum, connected to the computer and read that it burns every 150 km. so I decided to clean it, I bought a dpf cleaner on ebay and cleared the problem, the burning disappeared after cleaning only after 900 km! awesome! About six months later, the problem returned some 10,000 km more! and burning every 200 km, so ok, so I ordered a new dpf, I went to the channel, I replaced it and the key light with orange oil came on, I connected to the computer, the error was low oil quality, ok, I ordered castrol magnatec 5 oil, I replaced 40 Well, now the problem has begun, firing DPF occurs exactly every 60 km regularly Anyone know where the problem lies? do you need to reset it or something ??
Oh, the car has run 217 thousand service made from new every 15-20 thousand! the valve is replaced twice on the way!
If anyone had a similar problem, please help me because I have already lost my sight for kaman! 1

Regards !!

in the screen attachment from opcom!
made at 2500

Hello. There is such a function as a memory reset after replacing the DPF. You could try it.

Thanks gentlemen for the answer !

And you don't know what program can be used to make this adaptation? Is only the service remaining? I am asking because I live in Germany and magicians here at the workshop will take me away knowing the lives of several hundred euros! (I paid 270 euros for the new DPF) I'm also trying to cope here myself
Regards !

Op-Com can't do it?

Do you know how? I do not know this program, I would not like to support something ..... I'm not a mechanic. Do you understand?

First of all, I would check the injectors and turbine if they smoke, letting the oil run.
Because you'll instantly fill the filter.

Check the tightness of the intercooler hose, the one under the cover. He often rubbed.

What does the intercooler have to do with DPf burning?

Ordinary drivers should not rummage in cars like that since 2000, because they will not admire anything wise.

according to the parameters, you don't have a filter at all, that's why such circuses.

If you write that you are not a mechanic, you could at least check instead of asking silly questions ...
I did not write about the intercooler but about the snake leading to it.

Since you are a mechanic, can you write me what the hose leading to the intercooler has to do with firing DPF? But I am asking for substantive statements as much as you can. Why do you write that this is not a wise question? Isn't this the forum from this? maybe I was wrong FOra?
Thanks and I look forward to your reply

So what does this intercoler have to do with burning DPF?
Why exactly after 2000?

Op-com will manage, there should be a basic setting option or adaptation,
then reset diesel particualte filter

Thanks for the hint !!
So I will!

make for comparison the differential pressure at idle;
should show 0kPa; at 3000 about 4kPa;

The problem is the value of sediment mass;
After replacing with a new filter, the controller still compares the value of the pressure difference of the filter you had; the value he now receives from the pressure difference sensor is unbelievable to him and takes the correction for the reliability of the indications; sensor error will not be thrown because the signal is in the range of its correct operation;
The filter regeneration processes are becoming more frequent in order not to damage the engine;
Filter patency control is not only a differential pressure sensor but also temperature sensors before and after the filter; the temperature difference before and after the filter is different for a clogged filter and different for a blocked one.

But as I mentioned, the controller has a mass of sediments, i.e. ash, which remains in the filter and reduces its working volume.

So the adaptation must be done; otherwise he can't do it; there is nothing to look for and dig in the car until the mass zeroing is done.

This is called a specific answer, may there be more such people in this forum

1 kpa is at idle



I will do the Adaptation and drive a little we will see if the problem disappears! Thanks again

It's exactly as a colleague wrote prosty_01 .

Hello, I will join the topic. I have a Chevrolet Epica 2.0 VCDI 150HP on 180HP (engine designation Opel Z20S or LLW-Chevrolet) I also had a problem with firing on average when driving every 150 km, mixed mode 250km. I read on the net that burning should be even between 700 and 1000km. In addition, at the end of the exhaust I started to see a black coating, in the service manual for my car in the DPF department I read that this phenomenon qualifies DPF for replacement. I have access to Chevrolet TECH2, DPF clogging is shown in g (grams) and for me burning starts after reaching 25g. It lasts about 15 min (15-20km) while maintaining 3000 rpm and the right temperature. After burning, the program shows 0 g, but literally after a few moments the clogging reaches the indication of 14g, i.e. more than half and up to 25g you don't have much to drive. The information about the raid on the pipe tempted me to clean the DPF, I did it at DAKRO in Lublin (just a channel, disassembly - 3 screws from the back of the car cut off the rubber band could not be unscrewed corrosion, the engine side was ok, cut off should be knocked out - pins, I turned on bolts made of M10x35mm stainless steel - no workshop required) after installing the obligatory reset info on replacing the DPF in the computer. And now the indications quite different when driving hard jumps from 2 to max 14g at a time (it is 14g at about 160-190km / h) but when the engine slows down it drops to 5.8.10, g. at the moment I have 9g and 400km driven. I will add further information after 1 firing. I hope it will be useful to someone.
