Passat B8 1.6TDI Differential Pressure Sensor Error
Hi all,
I bougth a second hand 2015 Passat B8 1.6 TDI two months ago. After 1 week when i bougth, engine fault light was flashed on the dash board.
I went to the mechanic(not certified one) and he look at the fault code.
Fault code was that :
P023400 Diesel Particulate Filter; Differential Pressure Sensor - Intermittent
So we changed the sensor but couldn't adaptation cause my machanic don't have proper software.
After 1 week engine fault light was flashed again.
The fault code is shown like that
P245600 Particulate Filter differential sensor-1 intermittent signal
What should i do know? How can we fix this? I don't want to delete dpf system (my mechanic offered that)?
Anybody can help me?

First posts normally go in introductions else you could get a free fix and we never see you again!!!

What were those error codes scanned with a generic scanner as there are to many 00's?
You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing and check systems out.

Sorry for the late answer and location of the post. I deleted error codes last time and had to wait regenerate errors. Today the engine light flashed again but turned off in the evening.
i've just scan error codes.
These codes are :
As seen the logs, "Soot Mass Measured" value is very strange.
What do you think?
i've just scan error codes.
These codes are :
