Just an update on proceedings. Went to a DPF specialist who removed the dpf, stuck it in his machine and flush cleaned it. Result - limp mode now deactivated and car running normally. No warning lights. Exhaust gas temperature is still putting out a 999 value. It's not causing an error now but he said it might when it tries to regen and suggests replacing it. So I'll buy a new one and fit it myself.

DPF clean done in 3hrs at a cost of £320 Inc VAT.
