Hello,

i have Octavia 2016, taxi turned private.

mileage 279k km. 

its previous engine was gone (cxxb, 81kw), replaced with dgte engine (85kw).

had the dpf removed and cleaned using a special liquid.

now, after a month of silence, the MIL light turned on again.

scanning showed the following codes (image attached).

does this mean the dpf is still clogged and needs special cleaning? 

why is the exhaust sensor fault constantly triggered? the sensor was replaced.

sorry for that. any ideas?

A quick update.

after applying dpf cleaner spray to the exhaust pressure sensor pipe (after removal of the sensor), the fuel consumption was back to normal and the fault didn't appear again after clearing.

actual consumption picture attached before and after the cleanup and refueling-notice the reduction per the fuel quantity in the tank.
