P2002 again after removing DPF
« August 10, 2019, 08:23:02 »
Have the DPF removed today on my I30. The content of the filter has been removed. Had the error message P2002 before deleting. Now after the removal, the error code p2002 returns. Not as fast as before but the orange light is flashing again. And again P2002 fault.  How can there be a pressure difference when the filter is empty? What could be the error? Is the pressure senor turned off when removing the filter?

Thanks in advanced!

I would guess it flows too good now. I think DPF would create some back pressure, even when it is working properly. I assume they have programmed this in to the ECU.

Nevertheless, I have never heard you could remove DPF without reprogramming the ECU. Fault codes will appear. I assume you have not reprogrammed the ECU?

They also programmed the ECU. Donít know how or what.

From my reading the broad literature I too believe that no back pressure will trigger a fault condition.

I would go back to the shop and ask them to fix it.

How many km's did the car have before removing the DPF?

Being that the DPF on a diesel behaves much the same as a catalytic converter on a petrol I'm guessing the post cat/DPF oxygen sensor is detecting excess particulates due to the DPF not filtering exhaust matter, there are extensions that can be used on petrol sensors to help prevent this but I'm unsure if they're available or work on diesels :undecided: they would likely clog up quickly I'm thinking :undecided:

Only way I can think of is the DPF sensor needs to be disabled via the ECU.

Or some black electrical tape to cover the orange light   :winker: :lol:

The car has 277000 km. I will phone them tomorrow. Otherwise the black tape wil do the job.

Went back to the garage. Was a bug in the software, reprogrammed and fault is gone. When removing dpf they didnít switch of the dpf pressure sensor.

My late wife suffered from COPD until lung cancer killed her. Almost certainly exacerbated by us living 75 metres from the busy M42 motorway. Traffic fumes and particulates became a real problem and we moved house - but too late.  Hence if everyone removed the DPF the consequences on the general public who live in densly populated areas are obvious. They are installed in diesel cars for good reason.

I'm no eco warrior but do care when lives are genuinely at stake

In the UK I believe it is illegal to tamper with the DPF and I am concerned that this forum is being used to advertise practices that are at best, unwise - and at worst, illegal.

Rant over - I'll get me coat.................... :hatoff:

It's also illegal here in OZ, doesn't stop companies advertising DPF removal though :head_knock:

Ģood point thanks Alan. You certainly have good reason to feel like that.  :(

Like Gonz, I am relying upon the literature. Our Dutch friend has NOT said he is driving without DPF.

Normally the DPF is cleaned by way of a periodic burn off during highway travel. Low speed city bound cars do not do this and will at some stage require remedial cleaning.

That is all the forum has promoted .
