My 2020 m340
Love this thing but I’ve recently started having weird issue when I’m coming to a stop and I see some smoke come from exhaust and it smells like burnt oil. It all started when my mechanic added 0w-20 instead of 5w-30 and I changed the oil a couple days later. It used to be persistent, like almost everyday, now it’s happening less often (once a week). I don’t have any performance issues
My oil pump and my valve cover was replaced about 20k miles ago, we checked the turbos and everything seems fine. Any ideas what it could be? I’m about to take the car on a trip to PS and I don’t want to worry about being abandoned in the middle of the desert.
