Thank you for linking that, I came across it when I first got the code and couldn’t find it. Weirdly the check engine light went off on its own. I’ve never pulled the over flow tank before, is that the only sensor?
The upside to factory is you get a new sensor. The cft one is 6 times the cost and no new sensor.I canceled my z1 order and went with the cft wrinkle red one just liked the look of it
