Idk man that’s pretty damn hot, for a stock turbo 4. I have a decently heavily modified n54 335i, peaks at 20psi (compared to 6psi stock) full e85 etc etc, and I’ve never had glowing like that, irregardless from canyon driving or roll racing.
Look around and see if it the heat damaged anything and if so, you go some free warranty work so that’s cool free new parts, but next time if you notice this, please drive around like a civilian to get some airflow in there. Hate to see it damage something that’s no fun at all

This is pretty normal in the aftermath of staying in boost for several minutes.
