I am hoping to ask another owner with DFGA engine if they are prepared to run diagnostic test on their car that has no NOX fault to compare with my results. It is a block of 12 items in the VCDS menu (suggested to me by another VAG owner) and requires running the car up from cold on a 20 minute run.

IDE00021 Engine RPM
IDE00075 Vehicle speed
IDE00347 Air mass: actual value:
IDE04090 Exhaust temperature bank 1
IDE04098 NOx-sensor
IDE05357 Current temperature with NOx Reduction CAT
IDE09007 NOx sensor before SCR catalytic converter: supply voltage
IDE09009 NOx sensor after SCR catalytic converter: supply voltage
IDE09010-ENG188621 NOx sens. dwnstrm. of SCR cat.: target heat. temp reached-Bits 0-7
IDE09016-ENG188621 NOx sensor upstrm. SCR cat.: target heat. temp. reached-Bits 0-7
IDE09018 NOx sensor before SCR cat conv: NOx emiss
IDE09021 NOx sensor after SCR cat conv: NOx emiss
 

I am not aware where these "factory" data results may be available but taking readings from another car on the road would provide a good baseline. This may be useful to others with similar issues and to provide feedback on aftermarket sensors.

 

If this has been done before please advise.
