So my suspicions that my 59 plate A6 Avant low emissions TDIE is a problem software car were confirmed yesterday when I Rec ivied this letter .
It would be interesting to find what the final 'technical solution' is, be it calibration related (software) or a calibration to suit new hardware. Still no news on how these vehicles perform on the EU NEDC/NEFZ at EU5 limits though. Makes you wonder if the future EU solutions are 'just in case'.
