I took my 2000 Boxster in for an oil change and the Check engine light was on. While the car did have a whine, I didn't know what it was. I called the dealer and he told me it was the tires, "that's all it could be". It turned out to be a wheel bearing. Foreign Autohaus got everything squared away at an affordable price. The check engine light was an oil separator vs the O2 sensor I suspected. When they were done the car was so much quieter, I could hear a clicking noise. Jason told me to bring it right back, and when I did they focused on it. It would not duplicate on the rack. It didn't take long until they discovered the emergency brake cable was routed incorrectly. They fixed it, no charge, even though it was a new problem. I would recommend them for your automotive needs. My car is quite a bit quieter and has quite a bit more pep.
