Re: DPF Active regen wont start

Something is clearly working wrong. I see little reductions in your pictures, but not enough to reduce the soot mass to the common value after regeneration. In this condition, the soot mass increases continuously and the DPF will be clogged soon. When the ECU detects a too high soot mass value, firs...

Re: DPF Active regen wont start

Was the regeneration finished? You can verify this checking the regen duration value, it change to 0 when finished.
And the soot mass should be between 2 and 8 grams.

Re: Refresh isn't possible

You have 2 ways to enable the automatic data update: tap in the DPF image or enable the data auto-update function after connecting in the options menu.
When you see green arrows in the DPF image, the function is active.

Let me know if it works.

Re: New engine type?

I don't have data about your engine and no reports from users. If no engine groups works with it, I can assume it's similar to the new TDI engines launched with Golf 8 etc that have a new diagnostic setup. I'm working to make these new engines compatible, but I need to have a car to be tested and I'...

Re: DPF Active regen wont start

In this condition, the ECU should try to force the regeneration as soon as possible after the engine start, it's strange that this doesn't happen. The regeneration duration field shows 42 minutes so it seems that the ECU has started the regeneration. If you see the input gas temperature under 400°C ...

Re: Can't connect?

The ODBeleven adapter works only with the OBDeleven app, it isn't an ELM327 compatible adapter, this is the reason why it doesn't work with my app, but it shouldn't work wit h any other OBD app. This is a choice of the producer:

Re: 2012 Touareg CRCA , exhaust gas temperature

We can play with the parameter as we want because these is a new group so we don't need to keep compatibility with other engines. For example I can set the correct input gas temperature using sensor 3 in the first field and "simulated particle filter surface temperature" value in the second field. I...

Re: 2012 Touareg CRCA , exhaust gas temperature

I think you're right, there are only 2 temperature sensors in the exhaust line. I checked again in Elsawin and I see a page referring to CRCA engine that contains only description of sensors 1 and 3, then I see other pages with details about all 4 sensors (of which I've sent the printscreens) but wi...

Re: Is my DPF finished?

My personal opinion, absolutely not from an expert, is that the ECU reads all the parameters and "create" the calculated soot mass value. When some parameter doesn't stay in the predefined range or doesn't change in a predefined way, the ECU changes the calculated value to the field regeneration lim...

Re: 2012 Touareg CRCA , exhaust gas temperature

Are you sure about the sensors location? Because the ECU needs to know input and output DPF temperatures to make its calculation. It would be strange if the output gas temperature were missing. I give a check also in my documentation to find more information. About the EGR, the values of group 1,7,1...

Re: 2012 Touareg CRCA , exhaust gas temperature

CRCA isn't present in the app database, so you're using the engine group 0 as default. This group reads temperature sensors 3 and 4 of your VCDS picture, but I've recorded also the other 2 values in my analysis so it's easy for me to change them for your engine. I'll create a new group for CRCA type...

Re: Is my DPF finished?

I confirm what I've already written: suddenly the soot mass calculated jumps to the limit value to force the regeneration and the distance since every regeneration is around 30 km, too little. The DPF replacement should be the last action you can do, first you may change some sensor. The diagnosis w...

Re: Is my DPF finished?

The DPF system has some issue for sure. The sudden jump of the soot mass calculated means there is some parameter that the ECU consider out of range or implausible so it work in a sort of recovery mode starting regenerations earlier than usual. This is often caused by the differential pressure senso...

Re: Is my DPF finished?

I still don't see any image ... The oil ash percentage is the value you have to consider to check the DPF life. When i reaches the 100%, the DPF should be replaced, as the VAG engineers planned. The differential pressure sensor is probably what you've replaced, I don't think there is a single "press...

Re: Is my DPF finished?

I don't see the attached images, but I can understand reading your message. Oil ash residue is not a parameter strictly related to the regeneration process, it shows the amount of unburned oil ash that can't be removed by the filter because it doesn't burn during the regeneration. This value increas...

Re: Question regarding the way this app reads data from the ECU

I used Torque many years ago and I remember that it works using the OBD protocol.
My app use the canbus iso protocol instead that is more complicated. Sincerely I don't know if the 2 protocols share something because I didn't analyze the OBD protocol in depth.

Re: Info app in regeneration

Don't worry, the app is read only, it can't actively interact with the ECU. The regeneration finishes almost always around 25% of filling, this because to continue down to 0%, it would require many more time and fuel to keep the filter temperature high enough. When the filter is full, the high tempe...
