Recently got a 1993 325is, 5sp, OBC, 90kmiles. Invariably, after driving 5 or more miles, I hear 3 beeps, about 1/2 second apart. This is never repeated until the next time the engine is started and driven some miles. I tell my wife that it's the mother ship checking up on us, but I'd really like to know what is going on. There are no warning lights glowing and no messages on the OBC. Please don't tell me that I'm starting to hear things!
