Hi, folks - I'm new to the forum. Bought my '07 coupe about a year ago with 7800 miles on it and have put another 30,000 on it so far. The engine intermittently exhibits a ticking noise - can't predict when it will occur or how long it will last. I mentioned it to my dealer (BMW of Columbia, SC) at my last service and the service rep said it was not unusual for this engine; that it was a lifter which has not filled with oil and therefore the noise. He noted it on the service sheet and I went on my way. The car runs great otherwise. I have owned several Bimmers in the past ('72 2002, '76 2002, a German 320, '97 Z3 2.8, and most recently an '00 E46), and none of them had a similar noise - unless you want to count the '76 with thermal reactors (much noisier - sounded like a diesel!). Anybody had the same problem? Also - any way to calibrate the speedometer? Mine reads 3-5 mph high depending on speed. Thanks.
