Would like to retrofit a soot filter for our XC90 D5 (4.2003). As it is a filter system that is installed in addition to the existing catalyst, it has to be renewed if it was installed for more than five years or for more than 80000 kilometers in the vehicle. What is it supposed to be? The cat is completely functional, otherwise the TÜV would have criticized it. Our DB 230TE has the first G-cat and has been approved by TÜV with 260000km. Decade of politics or a vers The economic promotion programme, as additional costs for the cat of 1000-1200 EUR arise. But if you prefer to use the tax for approx. 40 EUR further, what is economic, the environmental zones should be united. In addition, a car without a soot filter in two to three years is worthless. What do you think about it? Stefan
