I am hoping someone can help me please, I have a 2012 Honda CRV and I have a DPF light with exclamation mark on, RAC said the car has already done a regeneration and doesn’t need a forced regeneration but the computer hasn’t realised and turned the warning light off. Has any one had any experience of this and any solutions. I took it for a DPF diagnostic and they said the light went off but came back on instantly. Any help would be greatly appreciated. Thanks
