I have a rotten egg smell here too, but it's coming from under the sheets.

I don't have the problem, but about a decade ago my dad did in his Mercedes. He was told it was the combination of the catalytic converter and additives in gasoline.

Rotten egg smell

It can be many things from sensors not working properly, a bad convertor or even a loose gas cap. Check the gas cap to make sure it locks and seals.
