An example of a regen:
Leaving work on Friday to go to Bristol, 10 mins into the drive I was slowing down to pull in from the dual carriage way to get some diesel.
As I got out of the car I got a wiff of soot from under the car.
After putting the diesel in I knew that the regen was about to happen. I kept the car in 4th for the next 2 miles, onto the M42.
The key sign is the mpg. Watch the current mpg reading. During the regen on Friday I saw the mpg drop to low 20s. Even in 4th at 70mph the reading should be well into the late 30s under normal conditions.
After a few miles the mpg recovered quite quickly. At this point I went into 6th and carried on as normal.
The problems can arise if the regens don't get chance to complete, and the DPF fills with soot. This can then throw up a limp mode.
A PITA, but manageable if you know what to look out for.
