Chapter 550: Check it with a stethoscope

"If you let me say it, I'll say it? If you let me sell it to you cheaply, I'll sell it to you cheaply? Wouldn't I be too faceless?" Fang Yuan rubbed his right thumb and index finger towards Liu Chengwen, and smiled extremely brightly, "I have dinner tonight to arrange a show, otherwise there is no need to talk." ”

"Forehead......" Liu Chengwen shouted about robbers and bandits, but he could only give in under the pressure of Sun Yanming and Fang Yuan.

"Don't tease Xiao Liu. Sun Yanming smiled and played a round game.

"Among the Japanese cars, the Japanese Sanjie mainly focuses on family cars, Subaru and Mitsubishi have formed their own characteristics, Mazda takes the route of family sports, Suzuki is dedicated to the development of small cars, and finally quit China by playing its own games, and can only turn to India. Fang Yuan asked Liu Chengwen, "Do you know what their common characteristics were in the 'past', and why is the leather durable?"

"I don't know. Liu Chengwen is unreliable in speaking and doing things, but he is still relatively realistic, not to mention that in front of Fang Yuan and Sun Yanming, he didn't dare to talk nonsense about running trains, so he simply told the truth that he didn't know.

"What else can these OEMs have in common?" even Sun Yanming looked at Fang Yuan curiously.

"Yes. Fang Yuan said, "In the past, what they have in common is that the technology is old or in other words, the technology is mature, for example, their naturally aspirated engines have been used for one or two decades, all the problems have been thoroughly understood, and they have been perfected countless times, of course, the leather is durable, fuel-efficient, and there are fewer failures." ”

"I agree with Fang Yuan's statement. Liu Chengwen is the store manager of Volkswagen's 4S store, compared with the Japanese naturally aspirated engine, although fuel-efficient and durable, he prefers Volkswagen's small-displacement turbines, fuel-saving power.

"Yes, Volkswagen on the small displacement turbine earlier, and there are more problems, especially the problem of burning engine oil and oil leakage, and the Japanese engine is more durable and has fewer failures. ”

However, in Fang Yuan's view, there is no good or bad between Volkswagen and Japanese engines, but they are suitable for different people.

Some people are afraid of breakdowns and do not have such a great demand for power, even if the power of the Japanese naturally aspirated engine is not so strong, they will be willing to choose.

Some people pursue performance, of course, they don't look at Japanese naturally aspirated engines, but choose German and American cars.

And the world is developing, energy conservation and emission reduction policies have been introduced, in addition to Mazda's brainless, insisting on naturally aspirated straight men, many Japanese cars have also begun to launch 1.0T, 1.5T and other small displacement turbines.

Even models like Lexus that still insist on using naturally aspirated air are more or less using new technologies to reduce fuel consumption and complete the task of energy saving and emission reduction.

New technology, new engines come out, in a certain situation does reduce fuel consumption, but the lack of new technology, engine failure is also revealed.

The engines of Honda, Toyota and other car companies began to increase the amount of engine oil on a large scale, and the phenomenon of oil emulsification was not spared.

At the beginning, some Lexus 4S stores replied that it was normal, thinking that it was caused by the cold weather and the short distance.

However, as the weather warms up and the temperature rises, the increase in engine oil still occurs.

Speaking of Lexus's engine, Sun Yanming also added: "Oh, by the way, Lexus's engine is still easy to accumulate carbon, and it must be cleaned up in time, otherwise the lack of cylinders and detonation will always be a big trouble." ”

Fang Yuan nodded: "Well, there is also a Lexus pump pad that is easy to leak, but fortunately, it is right in front of it, and it is easy to repair." The lid of the water tank is bad, the fan is sucking air inside, and the flocculent hairs are sticky to boil the pot, which is too normal. The 4GR stability of 2.5 is much better, but the power discount is also more obvious. ”

"The other one for Lexus is the mud gate. Sun Yanming remembered the Camry mud door that was very fierce a few years ago, and this happened to Lexus, which is known as a high-end Camry.

"I know this, and my colleagues in the store and I joked, do you want to buy a car? Liu Chengwen remembered the happy times at that time, and almost died of joy, "I just don't know what the specific reason is." ”

"Design flaws. Fang Yuan said that the engine compartment of the Lexus ES and the position of entering the mud are indeed very similar to the position of the Camry mud door.

Fang Yuan walked to the right front wheel and pointed under the wheel eyebrow, and said, "There are four holes above the right front wheel that connect to the engine, and when it rains, mud will be rolled into the engine compartment from this position."

A large amount of rain and mud littered the engine compartment, and even the soundproof cotton, crisper box, ABS pump and other places have mud stains remaining.

Rainwater and mud stains can corrode the paint surface and invade the plugs, causing poor plug contact, a series of faults, and even overheating and fire.

In the ES hybrid model, there is no water ingress because the electric motor line passes through this hole. ”

"Oh, I see. Liu Chengwen asked curiously, "How to solve it?"

"There is no good way to solve the design problem, but to stick glue or asphalt to the hole. ”

"Lexus's engine has carbon build-up, oil has increased, and its gearbox has stalled. Fang Yuan said that in normal low-speed driving, if you release the accelerator, you will feel like someone is shrugging a cart behind you.

"Gearbox frustration?" Liu Chengwen guessed the reason based on his own experience.

"In addition to these, there are also abnormal noises. Fang Yuan opened the door and swiped his fingers over the interior, "The door seal, the interior panel above the dashboard, the center console, the rear, the sunroof, and the front tensioner wheel, the wheel falling is abnormal, and the VVTI pump head has a rattling sound when the cool car starts, and the oil pressure is gone." ”

Fang Yuan and Sun Yanming paused after talking a lot, and Liu Chengwen asked curiously, "Is there anything else?"

"Still? Are you supposed to be a Luxgen Big 7? For the Lexus brand, there are already a lot of these problems. Fang Yuan couldn't laugh or cry, in the past, in order to ensure quality, each Lexus would be checked with a stethoscope before leaving the factory.

It is in these years that the spirit of the craftsman is no longer there, and the assembly and quality have declined somewhat.

"These problems are not so serious, but they are a bit of a bad problem. Liu Chengwen was a little hesitant, but he was very grateful to Fang Yuan and Sun Yanming, without these two who were engaged in second-hand cars, how could he understand the true situation of Lexus, if he bought it home with a black eye, hundreds of thousands, it would be a lifelong regret.

"Fang Yuan, let's go. After getting Liu Chengwen, Sun Yanming beckoned the two of them to hurry up and catch up with the big army, and suddenly, he found that Fang Yuan walked three times and turned around, as if he had found something wrong, "What are you looking at?

"Look at that female sales consultant, is she kneeling at the customer's feet?" Fang Yuan didn't dare to point out the direction, just shook his chin and motioned for Sun Yanming and Liu Chengwen to look over there.
