Hi Joel, good to hear you are enjoying your car.
I was having issues with white smoke and really poor fuel consumption so I bit the bullet and had work done on the dpf, egr and a remap. It's like a different car. Smooth acceleration, no lag, goes like a rocket and gets 10mpg more (that's 33%) on average.
It's the car I always hoped it would be. 136k miles and still going strong.
