That is dangerous. Are you getting these readings from a WB gauge or from an actual log? Could be your WB sensor is fried. Log lambda with Vag Com to confirm. Block 031.

Lol that would suck but ill check because my o2 sensor is about a month old

I am talking about your WB sensor, not your stock OEM Bosch (hope it's Bosch) sensor. They can burn out easy. That is why they have heat sinks. I am running one on my AEM Uego.


But def log with Vag Com to have a starting ground.
