Well, according to the software.. For instance-Astra's, Vectra's and the ilk
with the 1.9 Fiat engine and DPF require 2000rpm or more and MUST be in 5th
or 6th gear for the re-gen to begin- now that's actually over 70mph in
6th[1]...!

Not using the car enough to warm up, low mileage etc (15p per litre more)
