Customer Question

Hi ,have 2010 mazda 6 2.2 with 33000 miles on clock. It was serviced 6000 miles ago and last weekend while driving to stone henge the dpf light started flashing. Went to the henge then came back and still flashing and car still running as normal (no limp mode). The guy who serviced my car told me he plugged his diagnostic tool in and code 2459 and cleared it but it came back and he could do nothing else.
Just wondering if it is the service interval that needs to be reset.
Please help.
