Althought the DPF in my i30 hasn't been causing any real problems, it can be PITA because it has an ability to start the regeneration at the worst possible moment.
Monday morning, going into work, 5km before getting there... Regen! It gets aborted when I arrive there and shut off the engine. I don't like the idea of a toasty 600°C DPF directly below the turbo, where the oil has now stopped circulating and will be cooked by DPF's residual heat. Could be one contributing factor in not-so-rare premature turbo failures.
Tuesday morning, going into work... regen? Not yet, usually I can drive 100 to 200 km after partially completed regen before it goes again.
Tuesday afternoon, coming from work... regen? Now I would have time to drive and complete the regen, but... Nope, no regen.
Wednesday morning, going into work, would have no time to do more driving. 5km before getting there... Boom! Regen!
Thursday: same as Tuesday.
Friday morning, going into work, guess what happens at exactly same place than Monday and Wednesday? Yes! Regen! That's three aborted regens in a row.
During the weekend I drove about 150 km... regen? No. I'd bet what will happen at Monday...
Monday afternoon, going into work at evening shift: Do I have to tell what happened...
(that's what you see during engine braking when regen is active)
Wednesday afternoon, going into work, I predicted an another regen but miraculously, No regen.
Late night after the evening shift, going home, 5km before getting there... Regen! Like usually, 5km before destination, but now I have time to drive and complete the regen process. It seemed to go forever, I drove over 10km past home before turning back, and it was still burning so I went again past home and turned back after 5km. Just as I approached the junction to home, I noticed the regen ended so I made the turn and drove last 2km to home.
The next week will likely go without regen, but I predict the next one to occur the following Monday morning, so all that rumba of aborted regens after another is about to be repeated. An aborted regen now and then will not clog the DPF, but it needs to be completed sometimes. In this case being technically oriented sucks, because many average Joes and Jills don't know anything about that and they just drive around happily without worries.
