The DPF warning light is flashing on my Mazda 6 - does the particulate filter need cleaned or replaced?
My Mazda 6 has a particulate filter warning light flashing, despite two hours on the motorway. The car has never done this in four years of ownership. It's done 99,000 miles. Does the DPF need cleaned or replaced?

In that case, the likelihood is that the DPF has filled up with ash from burning off all the soot it has been burning for 99,000 miles. Two options. One is to have the DPF sent away to be chemically cleaned by the Ceramex process, which costs about £400 all-in. The other is to replace the DPF, which costs about £1,000.
