Since I purchased this car as certified pre-owned it has been back to the dealer for repairs 1/3 of the time. After multiple complaints to BMW-USA the dealer finally contacted me. Before that the dealer ignored me. I am still using a loaner car and the computer module must be replaced.
Certified pre-owned is only good if the company backs it up.
As you mention about computer module, am just curious, do you have the "i drive" in your car? I am researching on BMW's 2007 model 328i's and planning to buy one. Your input will be very valuable.
