BMW M 3 parked in the driveway and had been turned off for several hours I was wax the car when I noticed a puff of smoke coming out of the air condition vent so I sat in the driver seat to investigate out of habit I close the door I planed to open the windows and the convertible top to take a look the car went into antitheft mode and locked me inside the smoke became thick quickly I tried to break the window with my elbow with no luck I was getting ready to try to kick the window if I could reach it with my foot Iâm on most 70 years old so it was tough even moving I couldnât get out ..my wife and daughter Who were in the backyard and saw what was happening they broke the window so that I could climb out of the car I sprayed the air conditioning vent with water which is also dangerous but I had to put it out I then disconnected the battery as quickly as I could I have called an insurance adjuster and had mechanics look at it apparently the LCM or the light control module for some reason caught fire I was lucky I had someone there to help me someone else might not be as lucky I did breathing a bit of the smoke and Iâve had cough but I donât feel itâs severe I will have it looked out eventually would just like the car to be evaluated by BMW engineers to see if they can figure out why it caught on fire Before I pay money to have it repaired Iâm not sure I can drive it again
