when you get home, may I suggest you use some DPF Cleaner from LAUNCH UK £12, it's a small price to pay to keep the DPF faults at bay

when you next fill up with a tank of diesel, you just pour the DPF cleaner in, I do it twice a year
this reccommendation came direct from Jimmy O-Riley ( based around Biggleswade) , he is the DPF guru.
