While driving from Tucson to Seattle (via San Francisco and Boise) we had the Check Engine light come on. For a while it was intermittent but then became permanent and the power of the car dropped significantly. We took the car to one of the Bay area Mini dealers and they replaced the air mass sensor on the first trip and reflashed the DME on the second trip. Light stayed on.

When we got to Seattle we took the car to Northwest MINI. They found the same codes as the Bay area MINI dealer (2B5C Air Meter Plausibility, 2B5B Air Meter Plausibility, and 2746 Mixture) but took a different approach to finding the problem. They smoke tested the intake system and found a major leak at the "Throttle Induction T Fitting". They replaced the fitting, cleared the codes, and Chili ***** runs like he is supposed to - fast.

My thanks to the crew at Northwest MINI, they made us happy MINI drivers again.
