On my way home last Friday the DPF yellow warning came on. The manual said the diesel particulate filter partially blocked, drive at 60 km/h for 15 mins at over 2000 rpm. I did that but the light hasn't gone off and the car is now in limp mode. The car is a 2014 A5 2.0 auto. Has anyone else experience a similar thing?
I had a dpf specialist
have a look, they diagnosed it as blocked and have cleaned it as well
