Adblue RE

[sazimam11]

Helo guys,

is there anyone able to provide an Adblue (SCR) reset procedure, please?

This one does not work : http://forums.ross-tech.com/showthread.php?3000-2012-2014-NAR-Passat%28A32%29-TDI-CKRA-%96-AdBlue-Level-Reset-Procedure


In my case engine is CFFB, no fault codes stored, SCR fully filled - confirmed by measurement chanell but on the dashboard there is 600km remaining to NO START condition. It is EDC17 on UDS protocol.


159 Exhaust gas temperature sensor 1 127.4 ?C
161 Exhaust gas temperature sensor 2 -0.0 ?C
163 Exhaust gas temperature sensor 3 165.1 ?C
165 Exhaust gas temperature sensor 4 177.4 ?C
412 Reducing agent fill level 99.96 %
413 Reducing agent injector; activation 0.00 %
414 Reducing agent injector; resistance 12599 mOhm
415 Reducing agent pump; activation 13.62 %
422 SCR catalytic converter average temperature 171.4 ?C
426 Sensor for particle filter differential press; raw value 9 hPa

To much soot ? function will be don't works anymore.
Differential pressure i think is very high when you ride, can measure ?

[mihaiservice]

What kind of soot are in SCR ? :)
the only one way to reset adblue system are to turn on/turn off ignition for 30 times ,adblue mileage will be reset by default to 18.000km if adblue tank are full fill and no other component are damage on SCR system !

[CustomCars]

SCR none, but trapped in DPF. If DPF not work, Adblue will be not usable anymore, procedure will be hold.
Like i see, possible very high backpressure, better check all.

[mihaiservice]

SCR system can set/reset in any condition,dont matter if ask soot of dpf are at 99% !like i say before dont need any diag tool, only from ignition !

[autoden]

Don't make the mistake of thinking its soot causing a pressure differential all the time. It might be ash. Then its remove and clean, or replace.

Mate does you have any dtc for adblue at memory?If you have it you can not reset adblue also if anyone touched the file from the ecu also can not reset it.
Better Upload the file from the car here.

Thank you for replies but have to say no to the DPF load - see parameters below - it is at idle.
Forced regeneration was sucessfull.

I think its time for a new NOx sesor with its amplifier. Anyone knows what the readings should be?

[sazimam11]

I am about to AdBlue off this EDC17 due to price of the NOx probe - 600 EUR for something making the car unworthy...
Have you got some experience making AdBlu off in this case ?
Peace

[mihaiservice]

Hi
read ecu and upload the file,someone will do it for sure !

[gitko]

you need also and NOx off not only Adblue or ..... new NOx :)
