#Number One New Car #. Car and boat tax, does the name confuse you? In fact, cars and boats are the same household, so there is a car and boat tax. So do you know why water comes out of the exhaust pipe? It's not someone washing the exhaust pipe of the car,
It's because the car is flooded! Today I will explain it to you in detail. The story takes place late at night, a car is towed back to the store, the tow truck master explains a lot of things, the most important thing is not to start the vehicle, otherwise the consequences are unimaginable.
So the car was left in front of the store, because it couldn't be pushed at all. We started the inspection at the door. When I opened the air filter, I saw that it was all soaked in water! What's going on here? It turned out that the car drove in heavy rain and turned out to be a "submarine",
And also nuclear-powered! This owner is really creative, but unfortunately this is not his real purpose. The air filter housing is full of mud, which is inevitable. First of all, the ignition coil and spark plug should be removed to drain the stagnant water from the tank.
Because the water is incompressible, if you start the vehicle, the connecting rod will be bent, so the water inlet truck must change the connecting rod. The carbon deposits on the head of the spark plug are caused by severe burning of engine oil, which is even more serious after being blistered. There is also "cheese" on the throttle,
The reason is that there are too many carbon deposits, and "cheese" is formed after being blistered. The intake valves are also full of water, but due to carbon deposits, it takes a while to bubble. This also reflects the seriousness of the carbon deposition problem of the Volkswagen EA888 engine from the side. Summary:
After the spark plug and intake manifold are removed, the vehicle can still be started because the water in the cylinder has room for catharsis and does not compress the connecting rod. The owner said he had not started the vehicle. The carbon deposits on the intake manifold are blistered by water and take on "cheese" properties. furthermore
Water is also present in other parts of the vehicle. For access to the intercooler and water pipes, the bumper needs to be removed. After removing the intercooler, it was found that there was a lot of water in it and needed to be poured out. Vehicles without a second start after flooding will theoretically not have big problems,
However, there is also a very small probability that the connecting rod will be damaged, and it may break and break through the cylinder block after a few months. There is not much water in the oil pan, which indicates that the cylinder is well sealed. The wiring harness of the injection group is aged and broken. Problem Guidance:
What are the potential problems with the car after flooding? How to deal with vehicles after flooding? Please leave a message to share your comments and experience. Renarration: The spark plug was disassembled, and the intake manifold was also removed. At this point, you may be curious, if you want to start the vehicle at this moment,
What happens? In fact, since the stagnant water in the cylinder has room for catharsis, the connecting rod will not be compressed. The owner insisted that the vehicle never started after flooding, otherwise he would have had the car overhauled. In addition, carbon deposits on the intake manifold are also blistered,
It has a cheese-like character. Does this mean that we can wash carbon deposits with water in the future? This is truly an amazing finding. Since the cylinder is filled with water, then there must be water elsewhere, because the car cannot move, we can only get out of the car to deal with it.
First of all, we need to remove the bumper. It would have taken only five minutes to work on a lift, but in field combat, it would have taken half an hour to complete. The purpose of removing the bumper is to gain access to the intercooler and water pipes. Since water flows low,
The water entering the cylinder cannot be treated, but the surrounding water basically accumulates in the lowest part of the intercooler. Disconnect the water pipe of the intercooler, and a large amount of water will flow out. Should this water come not from the Yongding River in Beijing, but from the Yongkang River? Only the devil knows.
In any case, the intercooler was also disassembled. The intercooler is hollow, and usually in order to prevent the turbocharging system from deflating, the sealing is very good. Once water enters it, it cannot flow out. We could only pour it out, and sure enough, there was a lot of water in it.
Water in the human brain is easy to get confused, and the engine of the vehicle is easy to lead to overhaul. In theory, a flooded vehicle without a second start would not have a big problem. But there are no absolutes, and there are also very small probabilities. For example, when the vehicle turns off after the first flood,
The connecting rod may bend slightly. Nothing may have happened at the time, but after a few months, the connecting rod could break and break through the cylinder. Pump the oil out of the sump, and somewhat strangely, there is not much water in the sump. Does this mean that the cylinder is well sealed?
We can't manage so much, we have to deal with it quickly, and there are still a lot of cars to deal with. The fuel injection group wiring harness is really speechless, and all of them are broken and aged. Summary: What potential problems can occur with vehicles after flooding?
What should I pay attention to when handling vehicles after handling water ingress? Please leave a message to share your comments and experience. This is an article about vehicle maintenance, which mainly tells about a series of problems and treatment processes of car owners for vehicle maintenance. The article is clearly structured and logical.
When dealing with the problem of the fuel injector harness, the owner decided to replace the entire harness at once, because the harness had completely broken. However, he found that the position and function of the wiring harness plugs of Volkswagen and Audi were different, so he chose the wiring harness dedicated to Audi. Despite the slightly higher price,
But the owner decided to accept the choice. Next, the owner also needs to deal with the problem of standing water in the trunk. He found so much water in the trunk that he could even raise fish or Godzilla. The owner uses the principle of siphon to drain the stagnant water,
But at the same time, it was also found that the battery had been soaked in water and had yellow rust. He decided to replace the battery and drain the water. However, after the vehicle started, the owner noticed that the brake pad warning light jumped out of the gauge. Originally
The repair shop repeatedly advised him to replace the brake pads and discs, but the owner kept delaying, and now the brake pads are badly worn. In order to ensure safety, the owner had to replace the brake discs together and decided to use the original brake pads. To sum up,
The article mainly tells about a series of problems encountered by the owner during the repair process, as well as how he dealt with them. The article vividly depicts the importance and details of vehicle maintenance by narrating the experience of the car owner. For readers,
The article also reminds them of the need to deal with problems in a timely manner when maintaining their vehicles to ensure driving safety. Finally, the reader can think about the question: will you deal with the problem in a timely manner when faced with vehicle maintenance, or will you delay it?
Brake pads and discs are a very important part of a vehicle and have a decisive influence on vehicle safety. Domestic independent brand brake pads are very mature, previously produced by state-owned enterprises, quality is guaranteed. Of course, for some users,
Only the original ones can meet their requirements, so we will also supply the original brake pads and brake discs. I heard that Audi's brake discs are manufactured in a brake disc factory, I don't know if this news is true,
I hope that knowledgeable friends can give us popular science in the comment area. Although we are ready for the perfect delivery, we are always a little worried about a car that has been flooded, after all, there may be some problems after half a year.
When I was on the riverside in 2012, I was hit by a major flood and many cars were flooded. The workshop of our 4S shop was filled with flooded Audi cars, and it was a really busy time. It was later found that
Half a year later, some vehicles had a broken connecting rod and broke the cylinder block, including an Audi Q73.6, which fell off at high speed and the cylinder block was pierced. Due to the high quotation of our company, this car went directly to Zhejiang Lihua for repair.
This incident is still very clear in my memory, and I hope that this Audi Q5 will not suffer the same problems as that Q7. As a repair shop, in order to protect our own interests, we have also explained to the owner before repairing that the safest way is to replace the connecting rod.
But the owner said that there was no need, and any problems were borne by himself. Having said that, I would like to remind everyone not to drive into low-lying areas during heavy rain, even powerful cars can be submerged.
