The engine leaks! Water leaks again! Water leaks again! I really admire this quality

August 3, 2024

Before buying a car, a friend hinted that don’t buy a BMW, water leakage, oil leakage, I do not believe.
I really believed it this time!
This TM is 4 times, two of which are, antifreeze leakage, trailer into the 4S store, afraid of damage to the engine.
The car is a new car purchased in August 2017, leading the 530Li model.
At present, 120000, usually drive very carefully, basically no bumps.

For the first time
Date of discovery: may 5, 2021
Problem: too little coolant, there is a risk of damage to the engine!
Go to 4S store to repair, replace, antifreeze storage pot.
The picture above shows the bear appearance of the kettle before maintenance.

The second time
Time of discovery: October 2, 2021
Problem: too little coolant, there is a risk of damage to the engine!
The car was parked well in the parking lot. I went to drive after work and found that the car was covered with water. I didn’t pay much attention to it.
Get in the car and start the fire hint, there is little coolant, open the pot to see, it is almost leaking, the kettle is empty
Take a taxi home directly and have the trailer towed to the 4S store for repairs the next day.
Check that the screw locking device is broken, that is, a plastic accessory connected between the kettle and the engine, which is normal after maintenance.

It is late to get off work, the car can not drive, take a taxi home, 4S shop is also off duty, only tomorrow, repair

Also do not know what began to leak, do not know what is the cause, caused by the leakage, can only show that the car’s waterway, there are problems, there are serious quality problems.

In exchange for this thing, we don’t know what this thing is.

It’s not cheap.

The third time
Time of discovery: April 29, 2022
Problem: too little coolant, there is a risk of damage to the engine!
On Friday, the car stopped in the neighborhood. When I was driving out, I saw an exclamation mark on the dashboard and didn’t pay much attention to it.
When I got into the car to catch fire again, I found this hint and drove to the 4S store in the afternoon for maintenance and inspection, saying that the water tank might be broken.
This waterway can not be repaired by TM. The fittings of the whole waterway are about to be replaced.

There is also a dripping coolant under the water tank. About two days after this discovery, it is not too dangerous. If you get on the highway and get halfway up the long distance, it will be even more troublesome.

There are no accessories, none in the whole province, only goods transferred to other provinces and Hefei, because the epidemic in Zhengzhou has not yet been transferred, and the goods transferred from Hebei.

This is the water tank of BMW. It’s made of plastic and aluminum.

From April 29th to May 15th, it was not repaired to pick up the car, with a replacement cost of more than 8000.
The failure of the waterway system alone is almost 20000.

The fourth time
Time of discovery: may 19, 2022
Problem: when I went to work outside, the driver called me and said there was a bawling sound inside the engine.
Open it and see the blue water flowing out from a small pipe.
I was thinking, it’s not that the coolant waterway is broken again.
Sure enough, it was a small pipe on top of the kettle. From the point of view of the water, there was a crack. You said that he could not help, and the pressure was so high.
Call the 4S store and the trailer has been towed away again. This is the second trailer caused by the waterway.
This car is really speechless, and the domestic car is not like this.
Go to 4S store for maintenance, no accessories, can not be replaced, and other parts from other provinces, there is no information yet.

At the end, I want to go to BMW and say, if you want to improve the power and power parameters of the engine, you can.
Please stabilize the supporting cooling system (waterway) first, so as not to become a common problem. Let alone let the owners of BMW lose their trust in BMW.
Also ready for the next car, change to the 7 series, play like this, will no longer consider, this brand, understand. No more compliments.
