Chapter 216: Class (1)

got the answer he wanted, Sun Yanming drove the car to the Tianhong second-hand car market.

After parking the car, the two did not return to Zhenghong Car Dealership, and walked directly to Song Guoyuan's house after entering the market gate.

Fang Yuan drank more than a pound of liquor, but he didn't feel particularly uncomfortable, firstly, he was only in his early twenties, which was the peak moment of his life, and secondly, the wine he drank was good, the more expensive the good wine, the smaller the side effects after drinking.

The door of Song Guoyuan's house was open, and Fang Yuan and Sun Yanming saw at a glance that Song Guoyuan's BMW M3, which had been moved from the wall to the middle of the courtyard.

The BMW M3 was dismantled at the moment, with a deformed front bumper, a crumbling front bumper, and a twisted hood...... All kinds of spare parts were spread on the clean ground, and Song Guoyuan, who was shirtless, was busy dismantling spare parts with his head down.

It was now more than two o'clock in the afternoon, the hot sun was hanging overhead, Fang Yuan was standing in the shade at the door, it was too hot, Song Guoyuan squatted in the sun and didn't feel it?

Fang Yuan walked forward towards Song Guoyuan, first raised his head and squinted at the sun, and then looked directly at the master in front of him, feeling really speechless, this strange old man was really weird.

Hearing the sound of footsteps, Song Guoyuan turned around violently and found that Fang Yuan and Sun Yanming quickly stood up, his hands were covered with oil, and he was still holding a sleeve in his right hand.

But before he could speak, Song Guoyuan noticed that Fang Yuan's footsteps were a little fluttering, and he smelled that there was still a smell of wine on him.

Song Guoyuan frowned and said, "Did you drink?"

"Hello Master, I had a drink with our regional manager at noon. "Fang Yuan was very honest and didn't lie.

"Oh, drink with the leader. Song Guoyuan's frowning brows relaxed, "Why are you here now?"

Sun Yanming said with a smile: "Fang Yuan drank wine and couldn't go back to the car shop to receive customers, so he came to you to take a look." ”

"The impact of drinking and receiving customers is really not good. Song Guoyuan grabbed a cotton cloth on the roof of the car and wiped his hands, beckoning the two, "It's too hot here, let's go back to the house." ”

"You also know the heat?" Sun Yanming smiled and looked up at the sky with a very depressed appearance, "I thought someone was made of ice." ”

Fang Yuan didn't say anything, but looked down at the BMW M3.

The front wheels of the BMW M3 have been skewed, the front face is completely destroyed, and standing in this position, you can see that the airbag in the car has also exploded, and you can imagine the tragedy of the accident at that time.

Fang Yuan heard Sun Yanming say that it seemed that it was the car driven by his master, even if he had ten thousand curiosity in his heart, he didn't dare to evoke Song Guoyuan's painful memories, and besides, he didn't know how to repair the car, so he just asked softly: "Even the engine has moved from front to back, it's not easy to repair, right?"

Sun Yanming didn't take it seriously, and told Fang Yuan: "Don't worry, it's not a matter in your master's hands." ”

"It's easy to repair, but this engine is quite expensive. Song Guoyuan stood next to Fang Yuan, looking down at the engine compartment with a depressed face.

Fang Yuan knew that the BMW M3 in front of him was the 2011 M3 two-door carbon fiber top version, the engine code was S65 B40, with a maximum power of 420 horsepower and a maximum torque of 400 Nm, which was the last generation of V8 naturally aspirated BMW M3.

Fang Yuan didn't know how expensive this engine was, but he knew that this engine had 8 throttle valves, and it was more expensive to clean than changing the oil.

"What's so good about BMW's engine burning oil and leaking oil?" Sun Yanming really didn't understand Song Guoyuan's idea of repairing this car, "It's better to spend so much money to repair the car than to buy another car." ”

Song Guoyuan ignored Sun Yanming at a glance, and asked Fang Yuan instead: "What engines do BMWs have serious oil burning?"

"Well, N46, N52......" This is to test himself, Fang Yuan is a person who has a car dealer system, and after thinking about it for a while, he remembered several major engine oil burners.

N46, N52 engines are used in many of BMW's best-selling models, the problem of burning engine oil is mainly the valve seal, which will also lead to carbon deposition, emission system problems, and even pull the cylinder, especially those who have a long life, the mileage of the old BMW problem is so serious that it is not good to repair repeatedly, the owner repairs while driving, and there is no calm heart that will be tossed and crazy.

"The answer is very correct, the common problem is very accurate, and the basic skills are very solid. Song Guoyuan's eyes lit up, he was very satisfied with his apprentice, and added to him seriously, "In addition to the engines you mentioned, BMW also has an engine to pay attention to, that is, BMW's N14B16 engine." ”

BMW's N14B16 ENGINE IS A 1.6-LITER INLINE FOUR-CYLINDER TURBOCHARGED ENGINE JOINTLY DEVELOPED BY PEUGEOT-CITROEN GROUP AND BMW, WHICH IS USED IN MODELS SUCH AS THE C4L AND MINI COOPER S.

In addition to burning oil, this engine also has the car that cannot be found in the morning, and after a lot of hard work, you will find that the idle speed is unstable, which is mainly due to the failure of the high-pressure oil pump.

Its water pump leaks and causes antifreeze to leak, its timing chain is prone to failure, causing the engine to rattle when it starts, and the thermostat failure causes the fan to work on its own when the cold car starts, and it runs for a long time without stopping.

......

"I'm telling you, it doesn't matter if it's an N46, an N52 or an N14B16 engine, it's not a big deal. Speaking of the engine, Sun Yanming remembered the old Cruze of the previous car dealership and the 1.6L naturally aspirated engine on Yinglang.

Sun Yanming told the two that at that time, he had just become the store manager of Zhenghong Auto Dealership, and because of his lack of experience, he coveted several old Cruzes and Yinglang at a cheap price, and since then he has embarked on a road of no return to repairing cars, repairing cars, and repairing cars.

Thinking of the tragic experience at that time, Sun Yanming's heart trembles now.

Because of the LDE1.6L naturally aspirated engine power meat, giant meat, thief meat, when overtaking, the accelerator pedal was kicked into the engine compartment, and it still didn't leave.

Fang Yuan nodded, he understood that it was indeed dangerous to not be able to overtake quickly, and at this time, the benefits of fast acceleration of zero hundred were reflected.

"Even if the power is weak, the failure of the Cruze's 1.6-liter naturally aspirated engine is particularly troublesome to deal with, and like Sherlock Holmes, it requires divergent thinking and reasoning from all directions. Sun Yanming sighed and told Fang Yuan that the problem of burning engine oil and leaking engine oil in BMW N46 and N52 is really annoying, but the problem is concentrated, and it is those faults over and over again.

As long as the engine oil is burned, do not consider anything, that is, there is a problem with the valve oil seal, which is convenient for the owner and the maintenance master to find faults, and the owner can maintain them on time and accurately, and other spare parts are not easy to go out of the situation.

What about this LDE1.6 self-priming engine?

It has a lot of faults and problems, and I am afraid that the owner will spend less money, and the maintenance master will be too idle, and there will be problems in the same way.

For example, the pulse width of its fuel injection, this time the problem is found to be too high, and this fault occurs again after repair, it may be too low.

For example, its fuel injection is nerve-like, sometimes too thin, sometimes too thick, so that the repairman can't figure it out.

In short, the feeling that this engine gave Sun Yanming was that it was not uncommon for any kind of strange faults to occur, and later Sun Yanming also learned to be smart, knowing that he could not repair it, so he simply changed the engine and sold it at a loss.

"When you become a store manager in the future, you must be careful of some key models when collecting the car. Sun Yanming warned Fang Yuan with a resentful face, "Don't care how cheap it is, you can't accept it." ”

"You're exaggerating. Looking at Sun Yanming's gritted teeth, Song Guoyuan smiled, and the other party said, "The problems that Lao Sun said only happened to the 1.6L naturally aspirated engine, and the 1.6T turbocharged one in the later stage did not have so many problems." ”
