Technical Fan starting up when cold

Ok to complete this thread i put a bottle of wynns paf cleaner few days running and bingo!!! sorted out
If it is OK and settled down hopefully it will stay OK, as long as the Eloys fluid etc is doing it's job.
Did the Snap On Tool say how much carbon/ash % was in the DPF so you will know if any future problem likely, or will you just chuck in some more DPF cleaner now and again;)
Not sure how check amounts if ash, i could plug in again and check but what bit do i use?
