Re: Seat leon 2.0 tdi

Everything seems ok, but you should check the health of the filter checking the regeneration frequency. The internal part if the filter image is dynamic, it changes depending on the soot mass filling percentage trying to replicate the real filling, so almost clear with low percentage and almost dark...

Re: Audi CRTD engine.

This mismatch with 3.0 TDI engines is the reason why I added a special option in the menu to override the field regeneration limit. I didn't tested any 3.0 TDI so all the compatibility is based on user's reports. I read that many users have the same problem due to a different dimension of the DPT fi...

Re: Jump in Calculated Soot Mass

In your graph I sww what many users told me: when there is a fault in the DPF system, the soot mass calculated value is wrong and the soot mass measured, that usually doesn't make sense (negative values, etc) becomes the most realiable value to check. In your graph it seems the ECU forced the regene...

Re: Oil Ash Residue.

This is not directly related to the engine oil. This is a residue coming from the fuel combustion and it isn't removable, in fact when this deposit reaches the maximum accepted value, the filter must be replaced. Only in this case, using a diagnostic tester, the oil ash value can be reset to 0 corre...

Re: Support for CBB engine Golf V 2.0 GTD

From a technical poin of view, it would be possible. The problem is that it would require a too big effort for me because the protocol is totally different and I should implement its compatibility starting from scratch without any car available for long time to test it. I'm sorry, despite I'd like t...

Re: Jump in Calculated Soot Mass

You can open the TXT file with excel and create the graph using the columns you want.

In this case it's useful to include also the "time since last regen" and "distance since last regen" to understand if the regeneration happens due to limits reached.

Re: Audi CRTD engine.

Found the problem: it was a stupid code error.
I'm going to release a new version, then you can also let the app to read the engine code from the ECU.

Let me know if it works.

Bye

Re: Audi CRTD engine.

I checked quickly but I don't find any errors in the code. I'll give a deep check with a test in car.

In the meantime can you try to uninstall and reinstall the app? Just to check if it's a cache problem.

Re: time since last regen min

150 miles can be ok is you use the car principally in city and sometimes in highways. I have about the same distance and I drive in city almost always with one highway trip of about 2-300km during the weekend in which the ECU usually do the regeneration. You could increase this distance driving many...

Re: Audi CRTD engine.

Ok thanks for the detailed explanation. It sounds strange for me because my engine (and also the engine of my previous car) has a limit both in time and distance that are many less than your values. Probably you have a bigger filter (this is the reason why it starts to regen at 30 grams instead of 2...

Re: Audi CRTD engine.

I'm creating the new group 16 and I have a question for you: I see in your screenshots the values "Distance since last regen" and "Time since last regen" very high compared to common values for TDI engines, can you check if they increase correctly? Distance can be easily compared to your dash mileag...

Re: Audi CRTD engine.

Field Regen request status is a parameter I used in engines who don't have the Regen duration value. I used that to understand when the ECU is performing the regeneration process: for both parameters the value 0 means no pending or running regen activities; Regen Duration shows the regeneration time...

Re: Audi CRTD engine.

During next regeneration, try every engine group and check the parameter "Regen duration": if some group has value different from 0 I can merge that parameter to the group 10 to create a new group specific for your engine; if all groups have always value 0, I have no other solutions. Anyway, in this...

Re: Audi CRTD engine.

Green arrows on the filter image are static, the 2 green arrows next to the green car icon have to rotate when there are data receiving. I see those arrows in different angle position so I suppose they rotate. The red hourglass doesn't appear because the value "Regen. duration" is 0. This value must...

Re: Audi CRTD engine.

If green arrows don't rotate means no data transfer.
Can you see green arrows on the DPF filter image? Have you disabled the automatic data update maybe? Clicking on the DPF image you enable/disable the automatic data update.

Re: time since last regen min

The rating mg/km (or mg/min if you set it in the options) is the soot burning rate in mg for every km measured in the last 2km. The regeneration never finishes at 0%, this because when the filter is almost empty, the grams burned in the time are less than when the filter is full of soot (the soot bu...

Re: time since last regen min

Unfortunately I don't have experience in clogged PDF filter so I can't advise you about the right way to clean it. The forced regeneration is similar to the field one, so I think it doesn't give you more cleanliness. You oil ash residue seems to be low, I don't think it's the time to do a chemical c...
