Once again the DPF exclamation warning light has come on again with no warning whatsoever. This is the 3rd time in 3 months! 24 Sept, 14 Oct and today. I've had regents done at Honda dealerships twice (Huddersfield & Bradford) and now taking the car in tomorrow to see what the problem can be. The car was bought new on 22 March this year and has done 15534 miles, with normally the mileage being over 100 every journey, so I can't see it being lack of temperature to blame. I has also had the latest ECU software update. Has anyone any ideas?
