I just got my 325iT late December, and only have 900 Km on it. i found out in 5 or 6 times, when i step on the gas and start moving, the engine fan become extremly loud / fast turning. it also happened even when i park the car and step on the gas. it goes away sometimes in next traffic stop sometimes after a good 10 minutes.
i suspect it's to do with engin tempurature and the computer just increase the fan speed to cool it down. can anyone tell me is this normal? i just can't imagine having such loud noise is normal in any driving condition... thanks.
