Sulfur smell when I drive on the highway.?

Once again, close but no cigar!!! " Sulfer " or " rotten egg " smell is almost always an indicator of a lean mixture in the combustion chamber. Possible causes include.... Restricted fuel filter, kinked or restricted fuel line, plugged fuel injectors, faulty fuel pump, low quality fuel. It's best to have it diagnosed before more damage occurs as a result of a lean burn condition.

Most likely a Catalyst problem. If you are getting a rotten egg

type smell you may need to visit your local repair shop or

Muffler Shop. But don't just fix the problem but check into the

cause of the problem....ie..oxygen sensor, faulty injectors etc..

cadalitic converter, smells like sulfur or rotten eggs

Have your catalytic converter checked out.

Or you could stop eating pickled hard boiled eggs.

it's not the volvo it's you, lay off the ebans before long highway drives.

Check to see if your battery is being overcharged.

No. But your speakers are burning out.
