Back in July I had the DPF cleaned using a 3 stage process, this cleared the problem, however 2 days ago the light is flashing again.
Do the DPF cleaning fuel additives work?
I have followed the procedure to force a regen, but how do I know if this has happened, as the light is still on?
I have 92,000 on the clock, is a new DPF needed?
Trying to avoid paying out a small fortune for a new DPF, any help appreciated.
