071 Particle filter; difference pressure 513 hPa
072 Particle filter; field regeneration lock status 0
073 Particle filter; field regeneration request status 0
074 Particle filter; kilometers since last regeneration 7226 m
075 Particle filter; offset for differential press. 57 hPa

078 Particle filter; soot mass measured 48.00 g
079 Particle filter; time since last regeneration 1693 s

will this be the g450 sensor, i would like to ask how can i do a forced regen via vcds? when doing the regen can it been done when the car is stationary or does it have to be driven? if the sensor is fault how do i adapt the sensor and reset the learn values?

thanks

Its a good bet for the sensor. Im sure if you look in Adaptations it lists all DPF in there to adapt basic settings.

I recently had the same fault. Audi quoted £240!! I bought a new dpf pressure sensor off ebay for £46 and fitted it myself took 20 mins. I have vcds so done the adaptation myself. If you google dpf pressure sensor coding there are a few posts with how to code. Any problems pm me and il try and assist

thanks for the help

does anyone know what the maximum amount of soot is acceptable before a regen is not possible?
my readings are 077 Particle filter; soot mass calculated 18.31 g
078 Particle filter; soot mass measured 48.00 g

is regen still possible??

thanks

[danny851]

anyone have any ideas??

does anyone know what the maximum amount of soot is acceptable before a regen is not possible? both while standing regen and while driving regen ??


thanks
