Absolute rubbish, I've done two regens in the Superb since March and was never more 10km from home.

The way I notice my DPF regen is:

1) The current fuel economy drops significantly
2) When stopped, the exhaust crackles and sounds as if there’s a (tiny) muffler on it
3) There’s a strong smell from the exhaust
4) You can feel the heat from the exhaust
5) revs slightly higher at idle
From tracking it, mine regents every 200-250 miles, so I make sure to have a longer trip in there towards the 250 mile mark. A 20km trip should be enough to sort it out if the regeneration has started.

A few years back the car was only being driven 12k miles a year and had to get the dpf regenerated manually at the mechanics approx. every 10k.
Since I started driving it more on longer trips due to work, there hasn’t been a problem with the DPF for over 20,000 miles!

For the record, I don’t own a Renault.

I'm guessing Ford or Mazda?
