  The passenger side seat mat sensor, that triggers the airbag in an accident (i understand), has failed. MINI of charleston sc (close to where I live) inform me that it will take 3-6 months to get a replacement.

Service bulletins

Technical service bulletins and other communications the manufacturer sent dealers about this vehicle. Ask a dealer for the full document by its number.

• 11000632Hot-Film Air Mass Meter Return
• 10244507MINI electrical systems have continued to develop over the past few years. As a result, the demand on the batteries has increased. Breakdowns due to an empty battery or problems in the vehicles electrical system can have various causes, most of which are not due to the battery itself. For this reason, a battery replacement will permanently eliminate the problem only in the rarest of cases. The energy diagnosis test module helps to localize these causes. This document covers important information for the dealer on how to handle discharged battery complaints. Without performing the energy diagnosis test plan, the root cause of a discharged battery cannot be identified. In order to properly repair the vehicle the first time, it is very important that the diagnostic test plan is performed to completion; with all results taken into consideration.
• 10216755N18 engine high pressure fuel pump (hdp): limited warranty extension to 10 years/120,000 miles
• 10206696New RDC wheel electronics will be introduced with future generation MINI models. The new wheel electronics are identified as Huf Generation 5. These new wheel electronics will need to be programmed using the new tool when replaced or when depressurized (0 psi) for more than 2 minutes.

• 10162461Air Conditioning System Leak Testing. The customer complains of poor or no air conditioning cooling. After further diagnosis, the system is found to be low or empty of a refrigerant charge, but when using an electronic leak detector, no leak can be found. CAUSE: In most cases, an electronic leak detector is not sufficient for identifying small leaks in the system. Electronic leak detectors can give false alarms and can lead to an improper diagnosis of small leaks. A leak cannot be located exactly if accessibility is impaired (in the case of the expansion valve, evaporator or condenser).

• 10150356"Discharged Battery: Energy Diagnosis Must Be Performed. MINI electrical systems and advancements in vehicle technology have resulted in an increased demand on the vehicle battery. This SI will help the dealer handle ""discharged battery"" complaints. A discharged battery can have various causes, most unrelated to the battery. A failed battery is often the symptom and not the cause. A fully serviceable battery fails when an electrical component causes the battery to discharge; the battery becomes internally damaged and must be replaced. For more information, refer to http://www.batteryuniversity.com/parttwo-42B.htm. For this reason, replacing the battery is not usually a permanent repair. The cause of the discharged battery must be analyzed in order to guarantee a proper repair. To properly repair the vehicle the first time in the workshop, the diagnostic test plans must be performed to completion, with all results taken into consideration. The procedure below will guide the technician to properly repairing the vehicle and getting paid for a warranty claim. CAUSE Discharged battery."

In some cases, the red warning message may already be active. The CBS front/rear brake display is based on a mathematical calculation. Various influences are incorporated into this calculation (for example, vehicle speed, brake pressure, and rotor temperature). Due to changing driving characteristics and/or unfavorable environmental conditions, the calculated remaining distance may differ from actual pad thickness."
