It's tight. Was the oil full cap your issue? No codes stored besides the vanos solenoid malfunction, but that could of been caused by something else. No dash or warning lights what-so-ever previously until today and it was yellow brake, 4x4 and trans fail safe on the way home. Once I restarted it, it was like nothing happened, all lights went away. Running smooth as can be now. Major tune up 6 months ago, plugs 10 months ago. It did have low oil when they did an oil change last week, but checked the oil level today and it's fine. As for the O2 sensor, I can't think of a time when that has been replaced. If it was O2 I would image it would have other symptoms.
