Rotten egg smell

Postby Noddycar » Wed May 30, 2012 6:43 pm

Hi. My NC has a real "rotten egg" odour after driving. When I pull into the garage, the sulphur smell is quite strong. Any ideas on what may be causing this? Faulty catalytic convertor? I doubt it is bad fuel, as I have continued to buy fuel from the same place and it is not a problem in our other cars.

Thanks in advance!

Batteries that are overcharging also do this.

Caused by a faulty alternator regulator.

Thanks for the replies.... It is under warranty, so I will take it in to get looked at. Wanted to make sure it was not a common issue before I do anything.

Gearbox/diff oil can be rather pungent.

Mine doesn't do it - not that I've detected anyway. I use mostly Caltex Vortex 95 and the car has done 72,000km. I've experienced this odour following certain cars (mostly Toyotas) but never an NC.

Whenever I smell rotten eggs when I'm driving I look for the nearest new Commodore. :twisted: There's almost always one in front. It's a special feature of the catalytic convertor that Holden use that they can absolutely stink when new. It goes away as the cat wears out and stops working. :roll:

It's usually nothing to do with the fuel. You don't need sulphur to produce sulphur-like smells. Some hydrocarbons like methyl mercatan smell more like sulphur than sulphur does.
