hi guys
car is a 2012 q5 3.0 v6 tdi
customer claims all three lights (dpf , mil and glowplug spiral) appears on dash every now and then ..car goes ino a limp.he takes it out on the open road for a few miles and then all is ok for a while...someone before me cleared all faults on the vehicle so Im assuming this thing just needs a dpf regen ..soot mass is measured 28g and calculated 21g ..I must say they are constantly rising..maybe the values were reset before I got vehicle? (also if someone could point out the difference between these values to me?measured vs calculated)

so I go into basic settings..elec loads on .engine idling etc
activate "service regen of particle filter" and all I get is "not running- 41.056" ..after some time it says "aborted safety reasons"
also tried doing it under adaption
enter security code given 27971..go to adaption..change value from 0 to 1 ...it then still says security access required

am I doing something wrong?

Manual/Chemical remediation is needed, and advised, so the DPF doesn't catch fire.

Hi Jack!! So is 28g already above its threshold? I was under the impression it was somewhere near 60g..

I would search through measurement values, to find the problem.
Soot, ash, temperatures, diff.pressure, regeneration etc.

hey guys...finally getting back to this car...had my buddy at the dealership try to do the regen..it ran through the whole process and ended up with a regen not correctly complete status..anyway on my way back from the dealers engine light came on and the fault above is what I have...it clears but then comes back after a short drive... ive checked the wiki for fault description and from what I can see this sensor seems to be the culprit...





some measurement values with vehicle running


Address 01: Engine (8R0 907 401 J)

17:45:17
224 Particle filter; difference pressure 635 hPa
229 Particle filter; offset for differential press. 28 hPa
231 Particle filter; soot mass calculated 2.00 g
232 Particle filter; soot mass measured 1.96 g

sorry for the long post guys :-)
any advice?im leaning on replacing the sensor

Clean/check/change "CCC" The sensor and also snake the hose to DPF with lock wire and cleaner for obstruction.

Verify wiring from sensor to controller using WD.

If required remediate the system manually.
