Weird Smell ... Ideas?

[ChrisUUC]

It happens very rarely but sometimes I get this strange burning/Egg smell through the cabin when driving slowly or reversing.

 

Had the bonnet open the other night taking my Nismos off and got a wif of it then also ... more egg smell than burning, and know im not cooking up a fry etc

 

Any ideas? Car only has 7700 miles on the clock and no slipping clutch etc. Brakes are the ones that where there from new but have my new ferodos to go in soon

 

Thanks, Chris

Could well be the catalytic converter burning off some chemicals / coking up a bit.
