Beep when starting the engine

My car (323ci) has some wield beep when I start the engine. It will beep 8 times and stop then nothing happen . In addition, it has some rough idle issue the first time I start the engine, but if I drive for even a little while, there will be no rough idle issue.
I don't know if these two problems are related. Does anyone experience a similar situation or know the reason to the problem?
Thank you.

Is the outside temperature colder than 37 degrees Fahrenheit?

Thank you for the reply. Yes, most of the time the temperature is under 37. Is this the reason?

NP bud, it's a friendly remind from her it's 37/below outside. One of the cool features that E46 came with it =)

that's good. Thank you. For the rough idle problem, is is because it is too cold outside?

That I wouldn't have too much insight about it brother. I've had my girl since June and she's been great so far =)

Thanks, I think it is because the car is old and it is just normal for an old car.

If its an ice warning it should be accompanied by a brief temperature reading in the display console.

It was snowing earlier, I guess it was a warning. For a temperature reading, the sensor was broken for very long

8 beeps usually mean seatbelt reminder (for European version), during which time red seatbelt light is lit up. Euro version doesn't have switch in the latch mechanism, so you get 8 beeps wheather you latch before, after, or don't latch your seatbelt at all.

I think it was before I latched the seat belt but I did not hear the 8 beeps before. It could be the reason. Thank you.

I live in Northern AZ and we usually get snow this time of year. Almost exactly a year ago this weekend I bought my '04 330Cic and had similar rough idle at cold start issues.

I bought the 330Cic in Southern CA during the day and the engine idle was just fine. But the next morning after sitting over night in <30F the engine had a very rough idle upon start up.

It would barely stay running and over time it would even just stall and fail to start the colder it got. Ultimately with much help from this site I was able to do several DIY jobs to make my 330Cic run right in all weather.

Off the bat the following problems were corrected to help me resolve my rough cold idle issue:

New upper and lower intake boots (lower was cracked and upper was very hard)
Rebuilt DISA & new o-ring (common DISA Valve flap / bell cam failure)
New plugs
Re-flashed DME with updated software using WinKPF (there is a BMW Service Bulletin that references rough cold idle issues due to faulty DME software)

After those fixes my 330Cic starts right up in freezing condition. Our last storm in early 2012 dumped a few feet of snow and the Vert was left outside overnight as the garage was being occupied by motorcycles. Even with all that snow and nice the engine started right up and idled smoothly.

Hope you're able to resolve your rough idle issue and enjoy your E46 all year long.

My Ride: slower than yours
8 beeps for initial start-up without seatbelt connected.

Black ice warning happens every time the temperature drops to 37*F, with a readout and a beep!

The cold temp warning should only beep once, and as others have said the temp shows up on the readout.
