2012 imported BMW 318 (E90). At present, it has traveled more than 80,000 kilometers. Factory nameplate 2011. For almost 10 years now, the battery has been doing well without worrying about it.
60,000 kilometers changed tires and brake pads.
At the end of 2019, the oil leakage was serious, so we did a “big health care” in the factory.
Replaced valve chamber cover, oil radiator apron, vacuum pump, solenoid valve apron, valve cover cover plate, engine filter, oil pan, gearbox oil, gearbox oil pan, antifreeze, double iridium spark plug, cleaned throttle valve.
The price of a friend’s shop is at a discount.
In 2020, it was found to burn engine oil, almost more than 1,000 kilometers plus a liter. Find the reasons and solutions on the Internet and forums. It is recommended to add additives and replace valve chamber oil seal. I bought a small bottle that came with the “red line” when refueling. Continuous addition of 4 or 5 vials, injection of oil seal repair plugging agent, no relief was found, and then the valve chamber oil seal was replaced locally in October. At present, the mileage of running is not much, and the reduction of engine oil has not been found.
It’s been almost 10 years. The battery performed very, very well. The temperature dropped sharply in the past few days, and finally the computer called the police! Think about it should be the battery!
The battery model of this car was checked on the Internet and forum. The battery changed by the rider is 70 oz silver mark for Walter. So I searched for the local agent and came directly to the store after the appointment. Due to the extremely cold weather in the past two days, the battery broke down a lot, and the shop was very busy. Finally, when the repairman was free, the master suggested to start the car and then directly open the trunk and remove the battery.
Take a look at this battery or an AGM battery with start and stop function. As a result of doing his homework in advance, some riders said that the new battery needs to be registered and the QR code of the original battery should be used. So Tsai Tsai carefully took a picture of the original battery, focusing on a local close-up of a place like a QR code.
An old battery removed.
This is the box for the new battery. For 80 amperes, it is tens, 1200 meters more expensive than 70 amperes.
After changing the battery, put out the car and restart. One fault code has been eliminated, but there is still one fault code. I made an appointment for the maintenance of my son the day before changing the battery (in case there is a problem after changing the battery, it will be solved at the same time). It happened to be a 30-kilometer journey to the fourth son, which recharged the new battery.
It’s been a busy morning. Look at the outdoor temperature on the car’s computer-9.5 degrees. It’s freezing! It was almost 11:00 at the fourth son’s shop. I went through the formalities and gave them the car. The front desk asked for a cup of coffee and began to play with my cell phone. Look at it for almost four or five ten minutes. Take a look around the workshop. Seeing that my car is still in the station and the maintenance engineer is still busy, I took two pictures and went back to the lounge to continue to play with my mobile phone!
Almost half an hour later, the front desk told me to finish the maintenance of the live car. Get in the car and start the fire, but the fault light is still there.
Explain the situation to the front desk, the front desk said that there are many car repairs in the cold weather. I just finished it soon because of the reservation for maintenance. This fault code cannot be solved by maintenance. To completely eliminate the fault code, you need to go to the back of the workshop to connect the computer for diagnosis. Too many car repairs need to be re-queued, which will take about 2 hours. I can’t help it. Come this far. Wait! It was more than 12:00, so the front desk took the meal ticket to the customer’s restaurant behind to solve the stomach problem. The food was not bad, with some shredded chicken with fish, old meat of pineapple and fried spinach with eggs. A small bowl of soup. Ten minutes to solve the battle!
I went back to the front hall to the new car showroom and took a look around. It is found that the “forehead” of the front grille of the new model, whether the 3 series, 5 series, or 7 series, has been cancelled. Remember E90, when the model has not been changed, the “forehead” between the front grille and the cover of the 5 series and 7 series is larger than that of the 5 series. Later, the new 3 series also has a long forehead, but because the car is not long enough, the front nose is short, the overall proportion is not coordinated, and it looks uncomfortable!
This is a third-series second-hand car, this forehead looks uncomfortable!
This 5 series looks much more pleasing to the eye!
Now the whole department no longer has a “forehead”, and an open grille has been added!
In addition, the new X1 grille chrome-plated vertical bar has added a small piece, like “tusks”, which I think is not as good-looking as before. X3 is the same as before, it looks much more comfortable.
About 3 o’clock in the afternoon, the car test came out, saying that there was something wrong with the oxygen sensor. Simply eliminate? no, if you want to solve it, you need to disassemble it. The dismantling fee is 800. Find the problem and pay extra for repairs. Look, it’s almost four o’clock. If you fix it, you can’t solve it today. If you want to repair it, you have to leave the car in the store, and you have to drive another car or take a taxi tomorrow. If it is simply a problem with the oxygen sensor, it does not hinder the use, wait until the weather gets warmer. So drive back to work!
In conclusion, the battery alarm should be prepared in advance to catch up with the extremely cold weather. There is the same as my car, the 2011 (E90) 318 imported model BMW, the battery does not need to be wired, can not be cut off. Start the car (if it can’t start up and start with the battery) just change the battery! The original battery is Walter 70AHMagne760A. In addition, if you change the battery in a place other than the fourth son, you’d better make an appointment in advance. If there is a problem after changing the battery, the fourth son will solve the problem as well.
