Hi all,
After driving (longer drives, not short ones) my '01 X5 3.0i i notice a light smell of coolant. Before i bought the x5 in 7/08 the dealer replaced the h20 pump, belt, and fan (went out on the lot in ~12/07).

I check the coolant level ever week or 2 (i know, check my fluids all the time...lol) and has been full and have not lost any coolant in about a yr.

I took my x5 into the dealer back in 12/08 for service and got a 2009 328i (fun ride) for a loaner and noticed the same light coolant smell after i was driving it. Then i have noticed it on other Bimmers too. Is this a common smell from the v6 engines?

No leaks, no coolant loss over a year (just had to top it off, the dealer did not fill it all the way after replacing the pump).
