I drive a 2010 Auris 1.4 D4D which I believe is fitted with a DPF (contacted two dealers, given conflicting info!). Car has had regular long journeys and having done 80k it's never to my knowledge had any DPF warnings/issues. It's been serviced by Toyota so I'm confident it's had the right oil throughout.
However, I'm now getting paranoid that I could soon be facing some hefty bills if the DPF/EGR are getting towards shelf life.
Any advice / experience from anyone with high-mileage 1.4 D4D units?
