When I said in the name of economy I simply meant MPG, because that is all the bean counters look at and that's why they selected diesel powered vehicles. Then , of course you can cut back on servicing which, apparently is the major cause of the problems with the BMW engines according to the manufactures. Which colour parliament told us diesel was good ?? We just got a payout for the VW car we bought. As regards the DSG box, we've had 3 and all have had no issues at all. The problems with modern diesel engines comes from trying to force as many miles as possible from each gallon of fuel with the least emission particulates produced as possible, and we passed the reasonable limits of that years ago. Yes the DPF cooler on those engines is an absolute b*****d to change, I would never volunteer to do another.
