I took my 04' X3 in the other day for service and I got an 06' 325i (sweet ride for a car). I noticed that when you lock the doors on the new 325i the front headlights and the side markers flash so you know that the key you pressed actually locked the doors. My X3 does not do this. Is it because I don't have the alarm or is this a programmable feature that I just need to get the dealership to change? Thanks for the help.
