In my previous post and i couldnt get the regen working on DPF. i bought Multiecuscan 26 registration and reset all values and did a forced regen even though it was only 68% blocked. Watching the rpm rise to 3500 was crazy trusting my old laptop. Driven car mixed driving for an hour and no problems. Thanks for advice and may have been down to oil degradation problem, now a happy Croma owner again.
