So,

The diag reader picked up the following codes:
41F2 - electric fan activation
480A - particulate filter system
481A - particulate filter system
4D00 - exhaust back pressure sensor

Cleared, for the sum of £36.

I drove on the M11 at 70mph, for 40 minutes, and the DPF warning had reappeared after 25 minutes

Now I need to work out which of those codes could be causing the DPF to refuse a regeneration cycle, or if i need to force a regen somehow.

No intention of hijacking, I was hoping any discussion on the topic would benefit everyone

Any thoughts?
