DPF regeneration with VCDS

[@shanoon6]

Thanks for the video and all the comments; very helpful.

[@worbarry9735]

Is it essential to change oil after regen i have only just changed oil but need to force a regen with vcds

[@Lily7-n6o]

How do you know when it’s finished ?

[@lukaszM46]

do you have a video to trigger active regen while driving? i know its possible

[@drancyneuftrois3120]

Hi, according to VCDS my calculated soot is 16grams and measured 3 grams. Which one is more accurate, measured or calculated? Because it also gives the fault code dpf clogged.

[@TordAndreassen]

The calculated value is set by the ECU, its just a prediction. Measured value is based on difference in air pressure before and after the DPF.

[@IvanToman]

@@TordAndreassen How can these two be so much different? Possible sensor fault or?

[@TordAndreassen]

@@IvanToman I guess the algorithm for prediction isn't perfect 😉

[@haputomat5229]

If im doing this my soot mass measured is increasing and calculating is falling.

[@cvrljakromano]

Hi could you please explain me what you ment by enabling adaptation

[@TordAndreassen]

The access code you hit, in (16 - security access) is either adaptation enabling or Basic setting enabling. Anyway, its not important. Just hit the code you see to get access.

[@stajpi]

@@TordAndreassen i tried, it says accepted but still i cant click on basic settings

[@MrDzincca]

@@TordAndreassen where in programm its shows code?

Hi, i have a 2007 a4 b7 and sometimes the glow plugs blinks. I recently bought the car so i dont know if it means that is doing a dpf regen. No other warning light turns on. Should i worry? Also the pedal is not that responsive. Thanks, please respond.

[@TordAndreassen]

Its most likely emissions related, like a bad sensor or a faulty EGR. You should scan for codes. Get VCDS or buy a cheap OBD2 scanner if you dont have one.

[@simonmller9612]

​@@TordAndreassen what sensor could cause this issue ?

[@stewartgrindlay9760]

Can you force a re gen to re start if you have stopped halfway through a previous regen

[@TordAndreassen]

No, you have to do the same procedure over again.

[@pgroseli9759]

What do you mean : "POWER CONSUMER ON" ? please explain in detail . Sorry for poor English. I'm Brazilian.

[@TordAndreassen]

Turn on everything that consumes power; AC, lights, seat warmer, rear window defroster, radio/loudspeaker etc.

[@patrickkgroseli]

Soot mass = 50g. Is impossible regeneration??

[@patrickkgroseli]

Vcds message: timeout-not running / error

[@TordAndreassen]

The limit is 45g I believe. Above that the dpf has to be replaced

[@nicolaemargineanu4258]

The limit in 90 And you cam make a regen on road with VCDS.

[@Dinkelas]

hi, you question pls.When driving mode, is it must to be connected to software or just drive above 60-70kmh, on 2000rpm

[@TordAndreassen]

DPF Regen can be done in 3 ways: 1) Passive regen while driving. This happens when the exhaust gas temperatures are high enough to burn off soot. 60km/t, 2000rpm, 20 minutes. 2) Active regen while driving. The ecu initiates extra fuel injection, to help raising the temperatures and burn off soot. Both 1 and 2 occurs automatically. 2 Is normally done when the 1st process is incomplete or aborted (usually when frequently driving short trips, not long enough for the dpf to reach optimal temerature and burn clean). You can sometimes hear the active regen, because the exhaust sound changes to a more 'deep droning'. 3) Forced regen when stationary. This can only be done with software, like VCDS. I only do the 3rd option if the soot mass measured gets above 24g, and Im not able to do a long trip. It's not recommended to do a forced regen unless necessary, because the extra fuel beeing injected can dilute the engine oil, therefore an oilchange is desireable after forced regen.

[@Dinkelas]

Thank you for answer, it was very helpful...

@@TordAndreassen Thanks!, I actually found this comment easier to understand then the video itself.

[@Automat1kkk]

Hallo ;) Cooles Video! Danke. 😊 zufällig schon mal dieses erfrischende basische Aktivwasser aus einem Hydrogen Rich Water Generator schon mal kennenlernen können? Dieses Getränk ist einfach fresh! 🌱 Wieso? Also das muss jeder selbst herausfinden. und Nur soviel: Es verbessert das Blutmilieu - hast du dich damit schonmal beschäftigt? .. ❤

[@saulgoodman7495]

How long does the procedure take when regen with vcds?

[@TordAndreassen]

Depends on how much soot there is to burn

[@saulgoodman7495]

Tried it today but when i typed "soot" nothing showed up?

[@TordAndreassen]

You mean when showing measuring data? Try searching for 'particle' Then you should see both soot mass measured and calculated

[@Similitude81]

Still, it would be nice to know how much it should be on.

Hola buenas, cuando intento entrar a acceso de seguridad, al meter el código me pone: controller refused to send a sed, service not supported in active session. Sabes como podría solucionar esto? Un saludo y gracias
