Hi all,a new genuine particulte filter was Fitted about a month ago.to this zafira which had done about 45800 miles.after the zafira had been abroad.came back to us as a none runner.we found that the particulte filter was blocked solid after doing a further 1000 miles.it is not smoking when you run the car.it has it been overfilled with oil and runs okay.has any body had this problem before.and is there any way to clean out this filter!!! greg
