BMW said from Bavaria, Germany and always with a rich taste. Some people say that this is manipulation of taste, some people say it is the quality of taste, and some people said lightly, it is full-bodied flavor of the oil.
“Life is always not open around a BMW 3 Series, BMW is always not open around the oil leak,” “BMW does not leak? That may be false Taiwan BMW!.” Even the Internet spread all kinds of oil spills BMW scripts, ridicule aside, BMW owners can also see the helpless and sad.
BMW missing for so many years, manufacturers seem to no progress, many owners have become accustomed to, like, like, add a drain leak Calais.
owner complaints “Hula Cats coolant leakage.”
but the owner of the home has received a complaint, so I feel satisfied with the BMW seems to have oil leak this “traditional arts” was.
Recently, the very fact that the owners from Guizhou, the owner of the house in the complaint channel to initiate complaints. According to the complaints described, the very fact that in April 30 to buy the new 2020 models of the BMW 320Li M Sport Package Edition models, the emergence of coolant leakage fault in July 25. On-board computer alarm, suggesting that “reducing coolant, please fill coolant as soon as possible the risk of engine damage.”
Coolant this thing, probably a lot of owners in maintenance brother heard when the service said, “brother, you are a little less this coolant, add a little to your right,” similar words. But in fact, the coolant is not a consumable, in normal car environment, depending on the quality of the coolant General 2–4 years or more will need to be replaced.
The very fact that the new car just to mention soon appeared to reduce the coolant alarm, display is encountered no small problem. Home owners immediately made contact with Ms. Zhang.
The very fact that the description and the information provided can be seen July 25 failed the day, the vehicle is in a stationary state and not driving. And coolingLiquid in the absence of any external force and impact of the situation, constantly flowing from the chassis to the speed of light leakage apparently did not take long, the very fact that finally had to call the rescue vehicle will drag 4S shop after-sales service.
BMW 4S shop sale local thermal management module determines that the fault processing program given are free of maintenance and replacement parts. But it said that this can only spare parts imported from Germany, which also led after nearly 20 days of service, to August 15, Ms. Zhang was re-get the car. During this period, dealers are not in accordance with the provisions of national service for more than 5 days, provide spare scooter. Therefore, the overall cost of maintenance for users is huge.
is not alone! A large number of successive owners in the move!
Although BMW “leak leak leak” is not new. But this time, as a currently very heat, sales are good models, the new generation of the BMW 3 Series (G20 / G28) has emerged coolant leakage problems, and also occurs in the car just to mention a few months, even this tens of thousands of dollars a car will not commit “lower issue” appears in the BMW body, it is puzzling.
I then retrieve the BMW leakage related issues in the search engine and found the contents of the time span even extends to 2017, but only the content for the new 3 Series leakage problems, on several forums have very much post feedback.
than the
Forum reflects the new 3 Series car owners coolant leakage fault, and are to mention a few months or a few thousand vehicles within kilometers malfunction. As can be seen from the post content, the emergence of leakage owners should all suffered thermal management module failure.
because of the large leakage posting and replies reflect the situation of the owners, I just pick up a few more representative screenshots of the content of the summary.
As can be seen from the reply to the owners, has established leakage problems associated group, apparently the new 3 Series is already leaking a collective event.
In addition Replies owners have said that the previous generation 3-Series codenamed F30 / F35 seems to have a similar problem, did not expect the new 3 Series will leak. Search out before it also confirmsNow the owners of the feedback of 2017.
After further search, did find that as early as 2017, there are many older 3-series owners to reflect the presence of absence of coolant problem, and also appears in only a few thousand kilometers of new cars liquid leakage.
As can be seen from where a message, in the car owner is only 4,000 km mileage found that the problem of light leakage hardly coolant. The frightening thing is, the computer did not have an alarm, and if so go on, no engine coolant quickly due to the heat can not be burned.
And, as the owners of ridicule, each generation BMW seems to be missing the point of what it really looks like the real BMW ……

BMW staged “open new flowers and trees”?
previous generation 3 Series is a burst water pipe leak coolant, the BMW smashed and what play?
According to official sources, the new 3 Series is equipped with the latest code-named B48TU four-cylinder engine, B48TU relative B48B20 engine on old models in the 3 Series has a larger circulation cooling system, cylinder head design, etc. changes in the upgrade. Which for optimized cooling system, making more accurate temperature control, optimizing fuel consumption and emissions, ensure rapid hot car.
The leakage event and relates to a thermal management module, a role is to achieve a more complex multi-channel opening and closing control of the coolant flow. Such an important part in this play the role of technological progress, but if the design or quality defects appear, then will have a significant impact.
has yet to solve the oil leakage and other issues have become standard with BMW’s “traditional arts”, the new 3 Series has staged drama coolant leak, I do really want to let BMW owners have become “leaky horse” after the owner?
According to the current owners of the house to retrieve the complaints received and a summary of the whole network, the new 3 Series coolant leakage problem has been to show explosive trend, but more importantly, we can not rule out the coolant will leak into engine inside, resulting in greater damage. And after the repair, whether sequelae, will not leak again, etc.problem.
At present we have not seen any official response from BMW. For first-line luxury brands like BMW, this should provide a guaranteed quality and reliable products, but it has been standing still on the issue of the oil leak leak coolant, etc., to car owners caused great distress. Home owners will continue to be concerned about this progress. If you encounter car quality, home owners can enter the channel complaints complaints.
owners science Time: Coolant How important?
by the engine cooling system radiator, hoses, pumps, electric fan, thermostat, sub kettle, block and cylinder head cooling water jacket and subsidiary devices and other components.
Generally coolant circulation flow path in the cooling system there are two, what we called the “big loop” and “small cycles.”
Briefly, small circulation cooling liquid is circulated only in the waterway inside the engine, it is a cycle during cooling liquid circulating through an external radiator of the engine, i.e. the tank.
has a protective cooling fluid from the engine cooling system rust and corrosion, can effectively inhibit scale formation, to prevent overheating of the tank, reducing the evaporation of coolant, provide lubrication for the pump and other parts thermostat. With precise control of engine temperature, improve engine performance and fuel efficiency plays an important role.
