This ticking sound continued every time the engine was started when cold, but not when it was warm. I called my dealer after a couple of days and scheduled an appointment to have it looked at. I dropped the X3 off on the 12th day of ownership and it has now been in the shop for two and a half weeks. After eight days of trying to diagnose the problem they decided to replace the entire head or "upper part" of the motor as they described to me. The parts arrived at the dealership yesterday and they anticipate the repair to be completed next week. BMW NA has been worthless during this entire process.
My local dealer, COs BMW in Colorado, has been very understanding and cooperative during the process. I finally spoke to the owner of the dealership this week and she agreed to replace the X3 with a new vehicle. I ordered the new one yesterday and hope to see it by the end of November. The dealer said that BMW is going to take back the original X3 because they want to investigate the cause of the problem. Maybe they are having some issues regarding the N55 motor and are trying to get them solved.
What's funny about that is that they dinged the 2011 year model for having issues yet here is your 2012 having the issue and they gave your model year a recommended rating. I still have yet to read about a 2011 on the boards with engine issues and typically this is where people come to complain if they have a problem!
