Well back to square one again!!! The DPF light has come back on and as promised by my local Honda dealer they regenerated it again for free. They recommended that I replace the DPF which will cost over £1000 inc VAT and labour! I have also have contacted Honda UK customer services who have raised it to Honda HQ and they have come back with this:-
"Honda (UK) considers a number of factors when making a goodwill decision. These would be the age, mileage and Honda service history of the vehicle. I have looked through your vehicle details and I am pleased to advise that we were able to reduce the cost of the parts for you on this occasion. Honda (UK) have agreed to reduce the cost of the DPF filter from £791.35 to £450. We have also agreed to cover the cost of the gaskets."
Obviously there will be labour charges from the dealer bringing the total cost to £630!!
Does anyone think it would be worth writing back to Honda UK to see if they could cover more of the costs? Any help or suggestions would be greatly appreciated. F6HAD I have you in mind for getting this fixed once and for all if they cannot reduce the costs any further.
