Was reading a technical note off the elsawin database, and it seems there could be an explanation as to why some people have probs and some peopel dont - and it cold be linked to the S-tronic gearbox. You see on an S-tronic equipped car the DPF system talks to the gearbox and alters the shift points of the gearbox when in regeneration mode. Of course this doesn't happen automatically in a manual car hence more chance of the DPF getting completely clogged, as the driver may not know its needing clearing out and so wouldnt drive any different than normal. I've done over 2500 miles in my car now and i can quite honestly say its the worst 2500 miles a car can do, ie, nearly all stop start traffic driving, confirmed by an overall mpg of about 32. I have not had the DPF light come one once, as i suspect that because its a an S-tronic, it can maintain the level of soot better than on a manual where it doesnt have control over the way the driver drives - if that makes sense???
Thats what i reckon anyway!
