Re: WK2 to get diesel by 2013
Most of the diesels in Europe don't use any urea tank, the particulated is trapped in a filter (DPF) and burned each 600-700km by injection of fuel in the exhaust, thanks to the filter high temperature. This affects mileage as you are throwing away fuel, but there is no additional tank to fill. It can also create problems if you drive mostly in the city, where the DPF can't reach high temperature so the procedure doesn't work. In extreme cases the filter gets full and needs service.
