Aug 10, 2012 · ENGINE AND ENGINE COOLING:COOLING SYSTEM:FAN
This recall involves aftermarket parts sold by Valeo. Valeo is recalling certain engine cooling fans, part numbers 696121, 696273, and 696275, used as service replacement parts for model year 2008-2011 BMW 1-Series, 2006-2011 BMW 3-Series, 2000-2009 BMW 5-Series, 2004-2005 BMW 6-Series, and 2006-2007 BMW 7-Series vehicles. A metal-oxide semiconductor may overheat due to insufficient screwing of the semiconductor on the aluminum heat sink. This primary failure could cause adjacent components on the fan assembly motor circuit board to overheat and short.
Consequence: This condition could cause the fan motor to become inoperative, or cause the motor circuit board in the assembly to overheat, potentially leading to a fire in the engine compartment.
Remedy: Valeo will notify owners and replace the fans free of charge. The safety recall began on August 22, 2012. This recall is being conducted by Valeo, not by BMW. For further information, owners may contact Valeo at 1-888-718-2536.

Consequence: OVERHEATING COULD LEAD TO A FIRE, EVEN WHILE THE VEHICLE IS NOT IN USE. AS A PRECAUTION, OWNERS ARE ADVISED TO PARK OUTSIDE UNTIL THE REMEDY HAS BEEN MADE.
Remedy: BMW WILL NOTIFY OWNERS, AND DEALERS WILL INSPECT AND SECURE THE BATTERY BOLT CABLE CONNECTION AS NECESSARY, FREE OF CHARGE. THE SAFETY RECALL BEGAN ON APRIL 30, 2012. OWNERS MAY CONTACT BMW CUSTOMER RELATIONS AND SERVICES AT 1-800-525-7417.
