Service bulletins for the 2008 MINI Cooper

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

M1202102019-07-12. Service bulletin. EQUIPMENT:MECHANICAL; ENGINE. "Cooper S with N14: Diagnosis for Misfire Faults. The Service Engine Soon (MIL) lamp is illuminated and/or the customer complains that the engine runs rough (engine cold or warm) with any of the following misfire faults stored in the DME: * 2771, 2772, 2773, 2775, 2776, 2777, 2779, 277A, 277B, 277D, 277E, 277F - "Combustion misfire, cylinder 1..4", sometimes together with: * 2781, 2782, 2783 - "Combustion misfire, multiple cylinders." On rare occasions, the Service Engine Soon lamp may not be illuminated (with misfire faults still stored in the DME) when the vehicle is brought to the workshop. Multiple causes related to electrical and mechanical engine components, or poor fuel quality in combination with unfavorable driving behavior (low loads and short driving distances). This condition may lead to possible clogging of the injector tips, causing a disturbance of the fuel spraying pattern or excessive carbon deposits on the intake valves/ports, resulting in reduced air flow into the combustion chambers."

Fault code: 61/3."" This error in the test plan will not allow diagnosis to continue. The test plan error will be repaired with ISTA/D 2.36.0. CAUSE A DME calibration error in the knock sensor diagnostics results in an increased sensitivity threshold to cold temperatures."
M1707122018-11-26. Service bulletin. ENGINE AND ENGINE COOLING. Service Action: Retrofit of the Engine Coolant Temperature Sensor. Internal corrosion could form in the engine coolant temperature sensor. This corrosion leads to internal bridging of the contacts, which can cause an inaccurate engine temperature reading. This false reading could lead to difficulty in the engine starting and/or a "Service Engine Soon" lamp being illuminated.
M1104142018-11-13. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM; ENGINE. N16 Engine: Oil Leak from Cylinder Head Sealing Plug. An oil leak can develop at a sealing plug located in the cylinder head, just below the vacuum pump. The sealing plug was not tightened sufficiently during production.

M2101142018-11-13. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:DIESEL; POWER TRAIN. Dual Mass Flywheel: Diagnosis and Inspection. INFORMATION The following three criteria must to be checked, evaluated and the resulting findings documented on the repair order prior to replacing a dual-mass flywheel as defective: 1. Total rotational angle at no load condition (with applied torque less then 20 Nm) 2. Secondary plate longitudal axial play 3. Friction surface appearance changes due to thermal overload. PROCEDURE Refer to the attached "Dual-mass Flywheel Inspection" document for the complete inspection procedure. The dual-mass flywheel replacement is justified only if one or more of the following criteria are met: 1. The total rotational free-play measured at the flywheel gear ring is: Equal to or greater than 3 tooth gaps on N14/N18-equipped engines; Equal to or greater than 14 tooth gaps on B38/B46/B48-equipped engines. 2. The secondary plate total axial bearing play measured at outside diameter of the flywheel is: Equal to or greater than 3 mm on N14/N18-equipped engines; Equal to or greater than 5 mm on B38/B46/B48-equipped engines. 3. Significant discoloration in the adjoining area outside the friction ring, or a severe ablation/erosion of the friction area, is present. WARRANTY INFORMATION Warranty claims for replacing a Dual Mass Flywheel are subject to denial or debit when it is determined that the diagnostic procedures outlined above were not followed.
