    Hello. I'm needing to carry out a forced regen on the 2.0tdi BRD r4 engine. I've manually regenerated it to bring my soot levels down. Does anyone know the security access key/pin so I can use the forced regen function? Thanks I. Advance.

    I carried out the top procedure and drove for ages and manages to get the soot just under 40. It was up at 120ish. The glow plug light still flashing and dpf light still on. Can erase dtc but comes straight back on. All exhaust temps are showing good 800degrees before turbo and can see it going into normal regen but never completed. Figured a forced regen would sort it. Normally work with Nissan and forged regen cures it 98% of the time. Dtc is 008194 (particulate trap bank1) p2002 - 006 efficiency below threshold.

    Sensors are known to fail.

    Would it not show a dtc for the failed sensor though? It's a 2007 so not sure if it come under the top or other process on wiki. Top was working,just couldn't get lights off. So thought forced would reset system. So access code would be idea to try,failing that is there anything else I could try to figure the problem?
