I was wondering if anyone had considered modifying the regen process.
For example on my 407 2.2 HDi (EDC16CP34) a regen triggers at about 66% soot load, the exhaust gets up to about 450 degrees, and the car feels down on power, growls, and drinks fuel. However, on our 508 2.0 140 (DCM34_P) a regen triggers at about 70%, the exhaust gets up to about 600 degrees, and I barely notice it.
