After 30K miles of ownership, the P0401 code CEL showed up. There's definitely some EGR flow issue going on. It was reset last week and came back again a few days later. I since reset the fault and now it's coming back in 20 minutes of running the gas engine.
1. Is this covered under emissions warranty? (non CA resident)
2. I'm using top tier fuel i.e. Shell at every fill up, why am I still getting EGR foul up?
This car only has been running pure EV for 30K miles and gasoline for only 40K miles
3. Is the cold weather causing the car to run richer than normal and causing this?
4. How can I tell if it's a clogging issue versus an actual EGR valve failure?
I have a scheduled appointment with the dealer next week. I can only guess how much this is going to cost me.
