A4 B8 2.0 TDi: DPF = Differential Pressure Sensor Faultly

Hi,

Stangely, just after getting all my light to LEDs, I get the motor lght lighting.

I plug my VAG cable, get an autoscann and I get this error:

I go thru ETKA and find where is located this sensor, I take a picture to get the right reference...it's seems quite simple to replace.

So seems that my Differential Pressure Sensor has to be replaced? (Only after 52000Km!!)

What do you think?!

Replace the sensor with a new one, prone to failures.
When you remove the rubber pipe from the sensor, blow into them with compressed air.

OK, thanks for advise

I order the sensor yesterday....

 

[towcestervag]

you may need a software update on the new pressure sensor!
the last 2 that i have fitted worked perfect but the light will still come on until i had a software update done

 

[dave chante pas]

software update?
you mean firmware?? strange

 

[christof71]

Do not touch software.. Change the first sensor ,Replace the sensor with a new one, prone to failures.When you remove the rubber pipe from the sensor, blow into them with compressed air.

They came out with a new sensor, I had a faulty differential sensor which resulted in me replacing dpf, diff sensor, vacumm & software update. Wasn't cheap the part should comes with a 2 year warranty

 

[towcestervag]

its a software update !!
the ecu is updated to alter the parameters for the pressure sensor you sometimes get a little instruction note in the parts box telling you this!

Hi guys,

So, I finally buy new sensor, I've just replaced it, clear the faults, stop and start the engine several times...and seems that the error disappear!

I will see if it's appear after a short drive next week

Only on thing, I find this procedure to make the adaptation of the new sensor:


After fitting the g450 sensor adaption is simply as follows:
Select engine (01)
Login or coding 11
Type 30605 in the box and login.

Close controller,exit vcds. Switch ignition off ( i jumped out and locked the car for 30 seconds to be sure to send everything to sleep.

I have tried to realize this once my sensor get replaced BUT I can't access the "Login or Coding 11", It' grayed :s

Should I really to this adaptation?
If yes, how can I access this "Login or Coding 11" section??

Thanks for support

BR

Carry out test drive .If everything is ok, do not do anything else.
You can optionally check these values:



104 Particulate filter
Only on vehicles with particulate filter
Oil ash
[Ltr]
Soot mass calculated
[g]
Soot mass measured
[g]
Distance since last regeneration
[km]

Sorry for the thread revival but does anyone know why the box is greyed out for coding ii 11?? Entered in the security code but still nothing.

Thanks
