Temperature Flash & 325/328/330

[rsjet]

I have two pretty simple questions (i think)

First, i have a 95 325i and sometimes when its cold out i notice that the temperature flashes on the OBC and a beep is heard. This happens usually when I first turn on the car and its usually around 37 degrees I believe, although i think ive seen it at around 27 as well. I have seen this happen on the newer 3 series models as well. What does this mean?

Second, I am wondering about the difference in power that you can feel from a 325 to a 328 or 330. I know the 330 is significantly faster than the 325, but what about 330 compared with 328 and what about 328 compared with 325? The reason I am asking is because I am thinking about selling my car and buying an e46 328 or 330 and I'm not sure which one.

Thanks!

the ding is to let you know that freezing conditions can occur . . . nice BMW feature . . lol

second . . 325i has an 2.5 motor - 328 has an 2.8 motor - 330 has an 3.0 motor difference . . yes . .

so, why does it beep sometimes when i turn on the car and its below freezing but not other times?



for 2nd question, if i feel that the 325 is a bit underpowered, do you think i will feel the same about the 328? just wondering your opinion because i havent had the chance to go out and drive a 328 or 330 yet.
