Two engine compartment fires have already been reported with 102 cases of pump failures worldwide. No crashes or injuries have been reported due to the issues however. The pump in question is an auxiliary pump that helps cool the turbocharger and in case of failure can cause the circuit board to overheat. BMW said in cases that this does occur, a warning message will illuminate on the instrumental cluster.
The issue was first discovered in June of 2009 on a test vehicle and in April 2010, a smoldered electrical cable of the water pump was found on a BMW-owned vehicle. Owners impacted by the recall will be contacted next month with BMW replacing the faulty electric auxiliary water pump.
