Just to recap: I've been skiting on for years now about how during my apparent DPF regen events there is a large loss of performance and economy. recently I've noticed there are far more of them in the ~20-30C range. In the past couple of days, the events have occurred at distances of 70, 47 and 47km apart in suburban highway running and usually run for 10km or so.
Well, Yippee! I've had a couple of outcomes today. They pose more questions than answers currently, but progress is being made.
1) Data has been logged by a Subaru dealer for sending to Subaru today. It didn't happen until I was on the way back to the dealership, however I was able to have the event logged and demonstrate the performance deficit to the service manager. They reckon they'll get back to me, in the eternal words of Con the Fruiterer (old Aussie pop culture reference), "A cuppla days."
2) Typically the apparent regen initiated itself just before I arrived at work today (like, turning into the driveway) and before going to the dealer nearby. After some teeth gnashing, I drove around a bit and logged some of my own basic OBD-II data. The throttle position variable does indeed vary downwards under acceleration during this event, reverting to 78.43 or 78.82% upon release of accelerator. I have not logged it varying outside the event.
3a) Note the terms "apparent" and "event". One thing the service manager did tell me was the car was not logging it as a DPF regen- the last DPF regen logged was some ~670km ago.
3b) The service manager said he hasn't seen anything like this before. He didn't seem unhappy with my driving style and the dealership is familiar and experienced with a few diesel engine issues now. I hope Subaru don't impound the car for further testing!
More to come when results are in. I wonder what the thing's up to or thinks it's up to?
