This bulletin applies to 2014 Mini Cooper vehicles equipped with a 1.6L engine. An oil leak can develop at a sealing plug located in the cylinder head, just below the vacuum pump.

The sealing plug may not have been tightened sufficiently during production.

Use a spray solvent equivalent to brake cleaner to remove residue at/around the plug. Loosen the sealing plug and re-torque to 40 Nm. The plug requires an 8 mm external square drive tool.
