Loud Bang

[EnvyM3]

I was sitting at a stop light yesterday and when the light turned green, I started to go and i heard a loud bang. It was so loud that I though I got rear ended. It wasn't a sound like the engine backfiring but it sounded like it came from under me as if something slipped when the power went to the rear wheels. Anyone have any idea what it might have been. I have a 2000 323 ci / manual tranny if that helps.

Thanks in advance for any input.

No I don't but I was thinking it might be the throttle body. It happened to my buddy's 7 series and it was the throttle body. However, his is an auto and it only happened to him around 85 mph so I am still kinda puzzled.

Happened to my Pulsar/Sunny GTi once, i thought the car blew a tyre... but it was only gas that had got into the exhaust and then the car backfired and it blew flames from the exhaust.. i was frightened that i had broken something :S

My car did the same thing, I was going in reverse coming out of my driveway. I thought I blew out a tire or something, I have no Idea what it was and it hasn't done it since and the car runs fine.

The same thing happened to me two times in the last week.
I think its tranny related...its like you are accelerating slowly then you press a little harder and you hear a bang.
I turned around both times thinking I got rear-ended too.
The car is fine otherwise...I think its just the tranny taking a mis-step, I am not worried...The stealership will not be seeing me anytime soon.

Take it too the dealer and have hem check the carrier berring on the drive shaft. Sometimes they work them selves loose. and sometimes its just a sporadic thing. But it sometimes under load torques and hits the floor board.

I just checked with Gene Krantz at mission control and he confirms that it was a burst helium disk...perfectly normal and nothing to worry about.
