Default Bad smell on acceleration

Have an 07 460L. Lately notice bad smell inside my car (Really BAD smell ) every time I'm trying to pass some cars, or just simply drive faster than usual. Any ideas? Does anyone had the same problem? Thank you in advance.

Welcome to CL, richieLS.

There is a TSIB out for sulfur smell:

And this is a thread which discussed the same situation, there was no definitive conclusion other than to see the dealer with the TSIB.

Good luck with getting that resolved!

Thanx Encore888,
Thats what actually they told me at the dealership - try different gas stations. One mechanic recommended to try 89 instead 92, so I guess thats what is my next step. we'll see what happens.

I run BP 93 octane and don't have that smell. I would only use premium fuel...
Try a different name brand fuel...

A new catalytic converter in a new car can cause a sulphur smell at times. Hard acceleration would accelerate the odor.
