Causes
A rotten egg smell is often related to sulfur. In this particular case, it is possible the catalytic converter contains a buildup of sulfur. The root cause of the odor is usually worn or overworked parts.

The car has just gotten to 31K miles. Is it normal for the cats to go this soon?

Got it. The 1st article said that if the smell is intermittent is not a failure though

It happened twice and both times it was after hard acceleration and the smell only lasted for like a minute or less.

I am curious,

Why don't you take your car to your mechanic ?

It is not good to play doctor to yourself.

There's a federal law that covers cats. The bigger question is: why is your car melting cats? Blind guess: it's running rich.

It is running rich or it is not running correctly and unburnt fuel enters the cats and burns there ?

I still do not understand why he is not taking the car to the dealer IMMEDIATELY, since the underlying cause could be

potentially serious.

The car is under warranty so if something is going wrong it will be ok.

p.s. Running rich means more fuel than necessary or not enough air, right?

Correct.

No panic button here dear friend. I just want to help and point out that cats with problems at 31k is far from normal.

With friendly regards,

George

Per
Pat Goss: Ask The Expert

It's normal to have that odor occasionally.
Dealer found nothing wrong with the car.

If they can show you were aware of an issue and did not bring it in right away, they can deny you warranty coverage because you could have caused necessary damage by not bringing it in. Just a thought.

 

[335xi]

Good point. That's why I brought it in.

The dealer foreman said that even a batch of bad gas can cause this. The DME showed no codes, car drives 'mint' according to him. At least, i have that in writing, If something does surface later, I can show that I detected it and they did nothing.

 

[za3879]

I have this occur after short bursts of hard driving also. Goes away really fast. Dealer said there is no issue with my cats. Car doesnt have that many miles either.

If you drive the car hard only occasionally, it may scare the crap out of you, releasing gaseous sulphur. ;- )
