This may not be of any use, but in my Australian CTD when the car is in regen it idles 100rpm higher when stopped and in drive. I have the keep driving light in mine and it only came on for the second time since 2012 last week, so the regen is fairly invisible most of the time.

I've been wondering that myself. I've had mine since October 16 and put about 40k on it. I have not yet seen the DPF lamp. I do about 100 miles a day on the freeway though, but I was off work two weeks and figured I would see it while driving around town. Never did pop up.

90+% of my driving is in city streets and as I said the light has only come on twice. I just went to a freer road and kept it in a lower gear till the light went out. It took about 10-15 minutes.

There must be some sort of warning that you need to keep driving, surely? It makes no sense to just let the DPF get blocked without letting the driver know.

We don't get warning lights for a normal regen event.. this would be too much information for too many people here, thus we don't get it. The warning message to keep driving will only display in rather unusual cases where the soot levels have gone above where the regular regen starts.

That is how the region light works as well. I only saw it twice in 60K km of over 90% city driving. City driving here is much slower than what you have in the USA. Far to many 50kph roads and lights etc. Car almost never gets past 4th gear as it needs over 80kph before it will change up. Car has the 6T45 transmission and a 2.64 final drive ratio.

DPF lifetime is an interesting question, they've been in use in Europe for over a decade, and there hasn't been a spate of DPF replacements, it's not something I let myself worry about.

And the DPF on a DEF equipped vehicle gets a lot less of a work-out than a standalone DPF, (but it may be smaller).

I plan on keeping my Cruze until it falls apart, after eight years the only non-maintenance or recall item I have had is an engine mount replacement.

My only issue has been poor metal in the front rotors, which I resolved myself as I don't see the point of replacing rubbish material with more rubbish material.

Well I hope the DPF they use in the US is as good as the one used in Straya.

My Australian Cruze has a different diesel engine to the one grs1961 has and my DPF has been faultless since I bought new in 2012. Most of my driving has been slow suburban and the occasional trip.
