shane2.0 Posted October 9, 2020 Share Posted October 9, 2020 Hi There, Have an issue with engine management light on Audi a6 Late 2014 model facelift. Have done dpf regeneration on the car few times. Light goes off after doing the regeneration tests and comes back on after 25 kms drive on motorway. There is also no soot in the dpf. So wondering why still the error light. Code error at the moment says 'particulate trap bank 1 efficiency below threshold' Let me know guys Quote Link to comment Share on other sites More sharing options...
