Rusty,
Nope, that's never occurred with either of my 2.0cdti's. Fan overrun occurs for around 2-3 mins after a regen for me. Even after I've nailed it. Mine must have a mind of it's own. Although I usually realise when one occurs whilst on tickover, unless the music is on & I'm caught out. At a guess, I'd say it occurs around the 200 mile mark or after 200 miles covered.
Thanks.

So it isn't necessarily anything to do with a set period of time or distance. This is why it can go of at random times regardless of long or short journeys. Ours went off on Friday, we got in he car and it said dpf was full and continue driving, took it up and down the bypass a few times until the puffs of soot came out the exhaust and light went out.
Stigeye,
Yes the dpf regen does seem to occur when the filter seems to reach a certain level, annoyingly for me, seems to be during a short journey, after a long run. Shame we didn't have a dash function, where we could set a regen off, when it was convenient for us, during a long journey. I've never had a dash dpf light occur, perhaps I'm doing something right lol.
Although my car has now covered 55k.
I might as well enjoy my diesel whilst I can, before the smaller turbo petrol engines take over the world. Followed by the electric cars.
Cheers.
