Dealer refused to cover DME that failed immediately after recall 24V-608 work. In early June 2025, I contacted my local BMW dealership about an overheat notification I received while driving. They confirmed there was an open recall on the vehicle for a water pump connector (Recall 24V-608). I had the vehicle towed to their location. They sent me a video walkaround that characterized everything looked good, except the water pump connector which had failed. Several days later, I was informed the recall repair had been completed but when they plugged in the new water pump connector, the DME shorted and they had to unhook the battery. Despite my best attempts to get this consequential damage covered as part of the recall work, BMW refused. I was told I had to come pick up the car as-is or pay for repairs. When I looked into the issue further online, I learned that if I had chosen to pick up the car, hook up the battery and attempt to start and drive it, I could have found myself stuck inside the car (electronic locks) with a DME that literally caused the whole car to start on fire. Thank goodness I didn't go that route. After further investigation into the recall issue (24v-608), I have learned the entire basis of the recall was risk of a "thermal event" caused as a result the faulty water pump connector shorting out. BMW never denied this when I brought it up. It is infuriating that BMW is suggesting the DME shorting out is not related to or covered by the water pump recall issue. A risk of thermal event is stated in the recall notice, and the DME literally shorted out DURING the recall repair work. They quoted me something like $5,000-7,000 to have the car drivable again. I'm at a complete loss.

In a letter dated September 26, 2013, BMW Group submitted a safety recall notice to NHTSA identifying a defect condition in the vacuum pump oil supply that may result in loss of power assist braking in 76,191 model year (MY) 2012 through 2014 BMW 3-Series, 5-Series, X1 SAV, X3 SAV, and Z4 vehicles equipped with 4-cylinder engines (NHTSA Recall 13V-454).According to BMW, movement of the seal disk within the camshaft may result in blocking of the oil supply to the vacuum pump, resulting in improper pump operation and loss of power assist braking.On July 11, 2013, BMW initiated a change to the camshaft geometry that prevented the seal disk from blocking the oil port.BMW has not received any braking complaints related to loss of power assist after the design change was implemented in production.The owners of all affected vehicles will be contacted by mail and asked to take their vehicle to a BMW dealer who will install a locking ring into the camshaft to keep the seal disk in its proper location.BMW expects to begin dealer and owner notification in November 2013 and complete dealer and owner notification in December when the remedy is expected to be available.Based on the actions taken by BMW, this investigation is closed.
