Hello all, quick question for you guys. For 2 days my MPG was a lot lower than normal (DIC showing 35-40 rather than 55-60 on hwy). Wondering why this happened, Its back to normal now. I'm assuming this was DPF regen but never saw indication of it. No codes or abnormal operation.

Most likely a regen, they usually take about 15 miles of highway speed to clean the DPF and bring soot mass back down.

Depending on your fuel and driving habits you should see regens about every 600 - 1000 miles. Mine tend to happen about every 750 - 850.

Ok this makes sense. I've only had the car for 1 month, driven it 850 miles so most likely what I saw was a regen event. Thanks for the enlightenment
