Common Problems of the BMW M6
Derived from the 6-Series automobiles, the BMW M6 is a high-performance sports car that usually comes in two body styles: the coupe and the convertible. M6 owners should be aware of the common problems that they may come across so they can prepare themselves in the future. Here are some of them:
One of the most common complaints about the BMW M6 is related to its engine. Some of the 2013 M6 coupes and convertibles had engine oil pump problems due to a manufacturing process error, which may possibly separate the pump's driveshaft from the engine's rotor. This may have resulted to an increased crash risk and a potential engine replacement, which is very costly. BMW stopped deliveries and the owners of the M6 were asked to refrain from driving their cars until they were serviced. Only vehicles manufactured from July 19 to September 11, 2012 were included in the recall.
Another common trouble encountered with the BMW M6 is related it to its battery. The error was due to the M6's battery cable connection bolts that loosen over time. This resistance may cause overheating and electrical system problems. In March 2012, BMW recalled approximately 1.3 million vehicles worldwide. Aside from the 2007 - 2010 M6 models, the recall also included the 5-Series, 6-Series, and the M5. The National Highway Traffic Safety Administration noted that overheating may still take place even when the vehicles are not in use. Therefore, owners were requested to park their vehicles outside until the problem was solved.
In the 1980s, the frequent problems of the M6 were related to its cooling engine, service brakes, and suspension assembly. It was reported that a grinding noise came out from the differential clutch, especially during slow cornering. In the 2007 editions of the M6, most problems were related to its digital instrument panel, emission control, power train, and tires. It was reported that the gear indicator suddenly reverses when the engine is turned off with the gear selector. Also, there was an error in the software which caused incompatibility with the system's communication.
My BMW has an air-conditioning problem. It blows cold air and then suddenly stops working. What's this problem all about?
Your vehicle's air-con is malfunctioning, and this can be blamed on a number of things. The compressor could already be on its way out, causing the air-con to function this way. There could be a leak in the compressor or other parts of the air-con. If you hear some whining or clunking after turning on the air-con, there could be a loose compressor clutch or the air-con unit is already wearing out. It could also be that the system doesn't have enough Freon or refrigerant because of a leak. Sometimes, the compressor isn't the only thing that's malfunctioning. The condenser and the lines could be broken at the same time, causing the A/C to dish out cold air one minute and then circulate warmer air. After which, air would turn back cold. To prevent air-con problems, the system should be cleaned and serviced regularly.
I've already checked the coolant, but there's enough supply. I've considered internal combustion leaks due to a blown head gasket or cracked engine block, but this isn't the case here. Why does the engine run hot easily? It seems like there's poor circulation. What could possibly be the issue here?
This is most probably a case of poor circulation since there's enough coolant in the system and there's no evidence of leak. Poor circulation can be due to a stuck-closed thermostat, a faulty water pump, or a broken belt. You may have to check for a clog in the radiator if the engine runs smoothly when the vehicle is driven slowly but tends to overheat when driven on the highway at higher speeds. There could be a problem with the airflow if the engine runs hot and tends to overheat when driven around the city yet runs well on the highway. In which case, you'll have to look for a faulty fan, a broken fan clutch, or a malfunctioning relay or sensor. If you still can't figure out what's causing the overheating problem, it would be best to have the cooling system inspected by a certified mechanic.
How do you get rid of bad odor? It seems like there's mold and mildew buildup in my BMW M6, and this is the cause of the funky smell. I'm looking for a home remedy.
To remove the bad odor, you have to kill the mold and mildew growth in the vehicle. For a temporary fix, you can sprinkle some baking soda on the carpet or where the odor is coming from. Leave this for a few hours and then clean this off using a vacuum. To treat mold for good, you have several options. This include chlorine bleach, mixing equal parts of bleach and water. A mix of vinegar and water can be used as a spray as well. Other alternatives also include borax powder and hydrogen peroxide. A disinfectant spray can also be made using 2 cups of brewed green tea and lemon juice (using 2 lemons).
