Forcer regeneration FAP 2.0 TDI CR

[VW Seb]

Hello

 

J'ai un probleme sur une A4 2.0 TDI. Il y avait le capteur G450 HS (pression différentiel). Mais le proprio a rouler un bout de temps comme ca... Du coup apres remplacement du capteur, forcement le FAP est chargé!

 

Bref je souhaite faire une regenration. Je regarde sur wikirosstech et voila la manip:

 

2.0l R4 CR-TDI

 

With the newer CR-TDI engines there are 2 different types of regenerations available depending on the actual soot mass/load. If either the calculated or measured soot mass is above 30g but below 40g you can initiate a regeneration while standing (Idle will be raised etc.), a forced regeneration while driving is also possible. Once the values are above 40g (but below the max 45g) the regeneration while standing is no longer available and the regeneration while driving is the only way.

 

Regeneration while Standing/Idle

Prerequisites (General):

Ignition ON

Engine ON (Idle)

Fuel Tank at least 1/4 full

Transmission in Neutral/Park

Parking Brake engaged

Coolant Temperature above 70 °C (see MVB 002.4)

Particle Filter Load below Specification (see MVB 108.2/3, VCDS should give the specified values)

If the Particle Filter Load is above Specification the Particle Filter needs to be replaced since the car may burn down when regenerating.

Power Consumers ON (Light, Seat Heating, Front/Rear Window Heater, Climate Control)

Engine Hood Closed

[select]

[01 - Engine]

[security Access - 16]

Enter the Code shown by VCDS next to Adaptation Enabling (e.g. Regeneration while Standing)

[Do It!]

[basic Settings - 04]

Select Block for Regeneration while Standing

[Go!]

Follow the Instructions on the Screen

[Done, Go Back]

[Meas. Blocks - 08]

Select Blocks 099 and 108 at once.

[Go!]

MVB 099.2: Exhaust Gas Temperature before Turbo Charger

MVB 099.3: Exhaust Gas Temperature before Particle Filter

MVB 099.4: Exhaust Gas Temperature after Particle Filter

MVB 108.2: Particle Filter Soot Mass (calculated)

MVB 108.3: Particle Filter Soot Mass (measured)

Now let the Car run with Raised Idle until the Particle Filter Load is as low as possible (close to 0 %).

[Close Controller, Go Back - 06]

 

Regeneration while Driving

Prerequisites (General):

Ignition ON

Engine ON (Idle)

Coolant Temperature above 70 °C (see MVB 002.4)

Particle Filter Load below Specification (see MVB 108.2/3, VCDS should give the specified values)

If the Particle Filter Load is above Specification the Particle Filter needs to be replaced since the car may burn down when regenerating.

Power Consumers ON (Light, Seat Heating, Front/Rear Window Heater, Climate Control)

Engine Hood Closed

Conditions (Driving Cycle):

Vehicle Speed above 60 km/h (40 MPH)

Engine Speed between 2000-2500 RPM (4th or 5th Gear, Automatic Transmission in Tiptronic)

Duration approx. 10-15 Minutes

Exhaust Gas Temperature before Turbo Charger above 170 °C (MVB 099.2)

Exhaust Gas Temperature before Diesel Particle Filter above 150 °C (MVB 099.3)

Exhaust Gas Temperature after Diesel Particle Filter above 150 °C (MVB 099.4)

Drive the car based on the above Conditions until the Particle Filter Load is as low as possible (close to 0 %). In case the Regeneration fails there can either be problems with the Driving Cycle Conditions or with the Engine Hardware.

Enter the Code shown by VCDS next to Adaptation Enabling (e.g. Regeneration while Driving)

[Do It!]

[Adaptation - 10]

Select Channel for Regeneration while Driving

[Read]

Enter/Save 1 as new Value.

[Done, Go Back]

[Meas. Blocks - 08]

Select Blocks 099 and 108 at once.

[Go!]

MVB 099.2: Exhaust Gas Temperature before Turbo Charger

MVB 099.3: Exhaust Gas Temperature before Particle Filter

MVB 099.4: Exhaust Gas Temperature after Particle Filter

MVB 108.2: Particle Filter Soot Mass (calculated)

MVB 108.3: Particle Filter Soot Mass (measured)

Now Start the Driving Cycle and keep watching the Measuring Blocks (2nd Person required).

[Done, Go Back]

En fait moi je cherche le code a mettre dans "16" pour activer les reglages de base car le bouton est grisé. J'ai cherché un peu sur le net mais je n'ai pas trouver comment obtenir ce code. si quelqu'un a une info ???

 

Merci

bonjour avez trouvé la manipulation a faire car moi aussi j ai le meme soucis le vehicule n a plus de puissance et a la valise il me dit capteur de pression differentiel et accumulation de cendre dans fap et fap diesel trop elevée

 

merci d avance

A chaud, que donne un passage sur Autoroute en 4ème pendant quelques dizaines de kilomètres ? :drive:

Un Vag Com pour vérifier le niveau d'encrassement ?

le problème que meme si ton capteur de pression à été changer ton Fap doit etre bouché, si un code défaut reste enregistré concernant le fap ton calculateur interdira la régé, sinon chez audi ils peuvent lancer une régé statique, si tu le fait toi meme tu as plusieurs choix, soit tu dépose ton fap et tu essai de le débouché manuellement, soit tu as différent type de produit qui existe pour t'aider à le débouché :

 

le tunap marche super bien le pb c'est qu'il faut un pistolet spécial pour l'injecté : http://www.tunap.com/fr/nouvelles/filtre-a-particules-diesel-nettoyer-au-lieu-de-remplacer.html

 

chez Kent il ya se produit qui marche bien également : http://www.kenteurope.com/france/datasheets/85956.pdf

 

:excl: si tu as déja une perte de puissance importante il faut déposé le fap pour essayé de le sauver c'est le seul moyen
