Hi, thanks for your post, the cars been serviced by Mazda dealership since new so I hope the oil is correct, I've tried every kind of driving and nothing helps, it''s done this since I took ownership 3000 miles ago, I thought it could be that th dpf is clogged up a bit and therefore is taking less time to clogged up fully and then carrying out this regen, or could it be a temp sensor? If I only new what the main culprits of this kind of fault are.
thanks
