I don't have one myself, But I was wondering, what the regeneration process is all about? And how you go about doing it?
And what happens if you don't do it?

It does it automatically. The engine ECU decides when to do it based on the way the car has been used and then pumps a bit of extra fuel in which burns in the DPF and burns the particulates in the filter off.Quote:

As I drive a lot within the city on automatic mode I need to do this every 2 months or so.
The specialist VW RAC man came and replaced a knackered sensor and regenerated the DPF. Now after two and a half day's I'm no longer stranded in the Lake District and will have to go to work on Wednesday. Now I've got to go to Leicester. So not fair!!!
Yup. I actually said the same thing to Mark in an email. Personally I think DPF's are more trouble than they're worth. They reduce fuel economy, they're not suitable for vehicles which spend their whole lives in cities and they're just another thing to go wrong. Also, if things go bad the extra diesel injected into the engine can make its way into the sump and that's not good......Quote:

As for what the DPFs are worth, I am certainly glad that less crap is out in the air we breath even if maybe the added fuel consumption negates the gains.
I may be wrong but I was under the impression that they were one and the same method. The extra fuel caused the car to rev a little faster.Quote:

I really don't see why different VAG products would employ different ways of regenerating tbhQuote:

That's what I thought too but he was very sure that it is different, so I didn't bother with it anymore since then.Quote:
