How much soot does yours kick out when you give it the beans? I was following Mrs C last night and we had a race from the lights me in the ****ter 406 that she uses to go to the farm, usually full of carrots and hay bales! and Mrs C in the Audi. Needless to say she won but farkin hell the 3.0 chucked some soot out, I knew it did as in the past I have left a few people in a cloud of black smoke. Its a 2007 100+k miles None DPF model.
