It reads up to 100%. On my way to work yesterday, I am seeing the value getting close to 100%. It was reading 99.6% as I was 1/4 mile from the parking lot, but then looked again and the value dropped to 78%, and within about 100 yards, I see the EGT gauges going up. I was already pulling in to work, so I would wait until after work to see what that gauge does during a regen.
The freeway isn't far from the office. The engine temp was just getting warm enough as I got on the freeway and I saw a regen start up. As the regen ran, I could see the DPF Status gauge come down. When the regen was finished, the status gauge had gotten down around 30%.
If this is any indication, whatever this gauge is measuring, it seems to be the trigger to start a regen cycle when it hits 100%.
Very cool! I'll check these numbers out first chance I get.. Thanks!
