Try disconnecting the battery for half an hour. That will clear the codes. Hopeful it won't return.

I too own a CX7 and the DPF warning light is flashing. i've had it inspected by my local mazda dealer and we have been told the timing chain is stretched and out of tolerance. This needs to be replaced at a cost of £500 but are assured this will solve the problem. Seems a bit strange as the car has only done 40000 miles with a full Mazda service history.

Same as mine but my dpf warning light is still flashing and mpg has dropped from regular 39mpg to around 30mpg..my garage who had just renewed engine oil and filter are now telling me it needs new timing chain and this may possibly put the light out.. £785 for new chain..they also tell me the mpg has reduced because the ecu is constantly trying to 'remap' cx7 with 73000 2010 now needs new home !!
