Sulphur-type smell after a hard acceleration.

[2wheelfish]

I haven’t nailed this down, but it seems unusual and couldn’t find another thread on it. After a hard acceleration I seem to smell an unpleasant odor on the cab of the RR, like a sulphur type smell - like rotten egg, or hydrogen sulfide. For reference relatively new RR with about 3k miles and I typically use Costco gas in Southern California, and have never seemed to have that issue in another car. It’s not strong, and it goes away quick, but it does seem to be consistent. Anyone notice this, or know what this might be?

I smell a slight sulfur odor if I idle it in the garage, I figured it was the cats burning in.

I think Lynard Skynyrd wrote a song about this.

"oooooh, that smell!"


Yeah, the cats.

Or, maybe it "Smells Like Teen Spirit?"

Normal, when the throttle closes after a hard throttle, the cats are cleaning up the unburnt gas. Every ecoboost I've ever driven has done this to some degree.
