I thought that it automatically did it itself. You only have to do it yourself when the DPF warning light comes on the dashboard when the sut levels get to a more critical level. When we were driving to the Lakes on Friday night the car wasn't happy at 1800revs most presumably because at this rev range it was trying to regenerate itself. You have about 50 or so miles to regenerate it yourself before the engine goes into limp home mode and will then not rev above 1500rpm. Unfortunately the attempts to regenerate the Octy vRS would not work because of a knackered sensor. The specialist VAG RAC man used a quarter of a tank of fuel to regenerate it from limp home mode. The DPF light warning light has only ever come on 3 times on the Octy vRS and it will be three years old in March. Ironically the previous time the warning light came on was driving to the Lake District. It definately doesn't use a quarter of a tank of fuel when you regenerate it yourself.
I also know someone who ignored the DPF warning light. They were a bit miffed in the resulting £1k repair bill. Stooopid!My phone has an alarm clock! Ner Ner! :p

I'm guessing it used a quarter of a tank of fuel as it had already gone into limp home mode and the fact that it had been sat outside at sub zero temperatures for 2 and a half days and was clap cold when put on the regeneration programme by the special VAG man.
Special VAG RAC man has been having a very busy week. I'd be interested to know how much fuel he used on the 2.7l Audi he regenerated before us.My phone has an alarm clock! Ner Ner! :p

That sounds like a job for a garage.

If you can restart it and it will drive normally, take it for a motorway blast. If it remains in limp home after a restart then you'll need to take it to the garage.

More diesel runaway fun. Seriously though, it's best to take it to the garage, as soon as the oil level starts rising in the sump you run the risk of the engine starting to run on its oil and that is not something you want.Rule 1 of the forum, always accuse anyone who disagrees with you of bias.I would say that though.

It worked for FIATs 40 years ago, though I bet a diesel still doesn't rev that high.
I hate to say, but I agree.
