I also suffer from major oil loss in my 2014 Jetta se 1. 8. I had codes pop up telling me to replace some sensors, and turns out my oil was just very low. Within the first month I had the vehicle, purchased used in 2020, the engine was completely dry causing me to question the dealership's promise that an oil change wasn't done. I just replaced the pcv valve, but now I'm getting p0301 and p03af codes, and my car barely made it to work this morning. I had a successful test drive last night without any issues, but now I'm afraid to drive it at all without putting the old valve back in.
