Capability to read Particle Filter Load Coefficient

[draq]

As you know, currently I have an unofficial hardware 18.9, which doesn't allow me to enter into "Coding II - 11", once I'm into "01-Engine". The option is greyed out like in this picture (picture not mine):

However, I've seen some videos on YouTube where the option appears available, then you enter the code 21295 and you can read blocks 70 and 75 (where is included Particle Filter Load Coeficient):

So, would like to know, if I purchase the original VCDS HEX-V2 or HEX-NET, would I be able to monitor such parameters like in second picture? In case it's not possible to know beforehand, and if I purchase the equipment and such option is not available once I test it, can I get a full refund?

In the first picture, [Coding II] is disabled because the module uses the UDS protocol, which does not support that function.

The second picture is from a much older ECU that almost certainly uses the original KW1281 proctocol, which also does not support that function.

What ECU do you have?

Here it is

Address 01: Engine  (04L 906 021 DT)

 

[Uwe]

CRB engine? That ECU uses the UDS. It doesn't support [Coding II] and there are no numbered measuring blocks in such ECUs, but particle filter data should findable.

Yes but can't find directly DPF load? Do I have to make math calculations to guess it?

 

[Uwe]

Without knowing the exact ASAM ID of the ECU, I cannot tell you with certainty what data is available in the measuring values.

-Uwe-

 

[draq]

Can I get such ASAM ID or only manufacturer knows it?

 

[Uwe]

ASAM ID is shown in Auto-Scan or in Advanced ID in ECU directly. ID is Dataset plus Revision. Example:

I guess it depends on what you mean by "load". Soot mass in grams should be there. If you're looking for a percentage of limits, then I suppose you will have to calculate that.

[draq]

Ok so the answer is no.

 

[PetrolDave]

Ok so the answer is no.

If that's correct then it's a limitation of the VAG firmware since VCDS can only report what VAG have included in their firmware.

 

[Sebastian]

Not sure where exactly you are having troubles, this should be all you need for most/all modern TDIs.

IDE00434 = Particle Filter Soot Mass (calculated)
IDE00435 = Particle Filter Soot Mass (measured)

IDE06059 = Particulate Filter Oil Ash Mass (actual)
IDE06060 = Particulate Filter Ash Load Limit
IDE00433 = Particle Filter Oil Ash Volume

IDE01408 = Charge Limit for Field Regeneration
IDE01409 = Charge Limit for Service Regeneration
IDE01410 = Charge Limit Over-Charge

 

[draq]

@Sebastian I've found the desired value to measure is "IDE00435 = Particle Filter Soot Mass (measured)", but where is specified the maximum value for that? So I can get the load percentage in real time.

Start posting a full VCDS Auto-Scan with a current version of VCDS.
