Fine if you have access to dual carrage ways that's are empty and do long runs.
I pretty much only ever did short runs and the light came on whilst stuck in traffic.
And if you went home switched off, planning to go it for a pointless run in the evening when no traffic, that was no good as the light would have gone off so not in regen mode. Then Two or so days later sitting in traffic on the way to work the cunting dpf light would cone back on.
Well that's the issues I had!
it should still regen itself as long as you dont turn it off once the regen light is on
