The DPF light first started flashing in 2010 and I had it serviced independently. The DPF light remained flashing and my garage (I had used them for years and have found them trustworthy and reliable) advised me to take it to another independent outlet to get the DPF "regenerated", which I did. All remained well till service needed in October 2011. The DPF warning light is currently flashing and this has occurred at the end of a 280 mile trip on motorways. I am advised that the DPF should have regenerated during a journey like that but clearly it did not. The car has been serviced recently. When this has happened in the past the Mazda Dealer has "reset" the warning light and changed the oil. To resolve the flashing PDF light invovolved a trip to Mazda at Bognor Regis and cost £135 for an oil filter and oil change plus reset PDF. The Mazda semi-synthetice oil was £9.50p a litre please compare with Comma fully synthetic above. 2006 Mazda 6: diesel..dpf warning light flashing which has been solved I have a 2006 Mazda 6 diesel which has done 105,000 miles.
