Slight update.
I tried using an in tank DPF additive today to see if that helped any (Wynns - it is supposed to lower the temperature that the soot burns off and seems to have helped some people).
I went for a 30-40 mile drive to see if I could get the soot to burn off at all, but it doesn't seem to have helped.
Still can't get the DPF to regen.
I'm thinking the DPF is basically blocked and that my options are:
1) take the DPF trap off and flush it through with cleaner and a jet wash;
2) take the DPF trap off, check it (to make sure it does look blocked ) and order a new one off ebay (ca. £200);
3) take it to a Halfords service centre (they do a DPF deep clean for £85).
Anyone had any experience of any of these options?
I'm assuming that Halfords basically just spray inside the trap with cleaner with something like the Liqui-Moly or Wurth stuff and then flush it through, etc. But if it cleans it up enough to force a regen that might keep me going at least.
Any thoughts welcome.
Cheers,
