Re: New here. Please help

I don't have direct experience like yours. The input gas temperature normally stays between 600 and 700 degrees thanks to the post injections 2 and 3. The additional fuel injected increases the gas temperature. If your temperature fluctuate, you can check the post injections to understand if the val...

Re: Interesting subject

In my opinion, it's impossibile that your car didn't regenerate for years. The standard diesel engine working mode, since DPF exists, includes regenerations. You can be lucky and have them very spaced up, but you can't avoid to have them. I've never heard or read about engines without regenerations....

Re: Interesting subject

Ok now it's clear. Your analysis is correct, but the 2 possibile regeneration methods differ in the soot burning rate, in fact the active regeneration is extremely more powerful than the passive one. You can see this taking a loot at the charge rate value (the first on top right) while active and pa...

Re: Interesting subject

I'm not sure to understand all your post, but my first question is: what's the problem you see? In the pictures and in your description I don't read any problem. Maybe you want to keep the soot mass value stable just driving at high speed/revs? In this case you have to check the gas temperature, whe...

Re: 2020 2.0 TDi EVO Engines support

The last full version contains the new group 18 for DTTC 2021 engine that I tested physically. If you're using the free version, the engine group 5 should give you readable data, but your problem is that the initialization doesn't finish correctly. With DTTC engine I've verified that the protocol is...

Re: Regen every drive

I agree with you, this behavior can mean a sensor failure. Moreover I see the measured soot mass with realistic values and this happens when the calculated value isn't correct (usually the measured value is negative and not realistic). I think that the ECU starts the regeneration so frequently becau...

Re: Newbe here with some questions.

How much km after the cleaning?

Sometimes I've seen similar behavior solved after 500-1000km. It seems that the ECU requires some distance to "learn" the new information.
Maybe it's a choice made for safety reasons, could be a logic choice.

Re: Motor DEUA

Usually the very low cost adapters work only with apps that use the OBD protocol only with common PID requests, like Torque.

VAG DPF requires a good quality adapter to manage a more complicated set of requests.

Re: Newbe here with some questions.

It depends on the driving style, but in the worst case (driving always in city) you should have at least 200 km more or less between regenerations.
A medium value can be 250-300 km.

Re: time since last regen min

I know this situation, it happens also to me very often driving in city.
My experience with filter additive is the same: the result was worse than expected so I never used it again.

Re: Motor DEUA

The low quality of the adapter could be the reason why you can't connect.

If you want, you should try a good adapter like "Carista" or "Vgate iCar 2 bluetoot"

Re: What does low EGR mean

Yes, the pre-injections and post-injections add more fuel to the main injection. The value you see in the app is the quantity added for every combustion cycle. In the normal condition, these additional injections are used to reduce emissions and reduce engine noise. During the regeneration process, ...

Re: What does low EGR mean

The injectors are the same used for the normal injections (one for every cylinder) but they can be commanded more than one time for cycle: you have the main injection containing the fuel quantity required by the accelerator, moreover the ECU can command up to 3 pre-injections and up to 3 post-inject...

Re: Newbe here with some questions.

The parameters are ok, but with a static picture it's impossibile to understand if your PDF works correctly. Using the app regularly you can check if the regeneration process follows the common behavior, for example you can check if the input gas temperature reaches at least 550-600° during the rege...

Re: What does low EGR mean

The value means the injected quantity for every engine combustion cycle (stroke). The pre and post injections are used in modern engines to control the noise and to reduce pollution, but also to start and maintain the regeneration burning process. Especially the post injection 2 and 3 are dedicated ...
