Volkswagen Langxing refueling speed can t get up

According to the above vehicle fault phenomenon, combined with your vehicle condition and fault conditions, this intermittent failure, first of all, to confirm whether the engine speed is too high when the fault is reproduced, if the engine speed is too high, it means that the internal performance of the transmission is poor. If the engine speed is within the normal range, it means that the engine is in poor condition (ignition performance such as high-voltage coils). In addition, this fault judgment method also needs to go to the maintenance shop to use the maintenance diagnostic instrument to analyze the data flow of the engine control unit, and detect whether the control signal is within the normal use range (such as the mass air intake sensor).

Secondly, this kind of fault also needs to carry out a pressure test on the fuel system to detect whether the fuel working pressure is normal, if the fuel pressure is unstable or too low, the above fault phenomenon will occur. In summary, it is recommended to distinguish the dynamics when the fault is reproduced to facilitate fault judgment, and if there is no problem with the engine and transmission, it is recommended to test the exhaust system (three-way catalytic converter) and fuel pressure.

I really want to help you.,You're really willing to give rewards.,But this topic is really difficult.,It's all guessing if there's no situation.。。。 Manual, automatic, and not telling.

If you refuel, the speed will not go up, and there are many possibilities. For example, is there a problem with the throttle, is the oxygen sensor broken, the air flow meter, the fuel injector, the oil pump pressure, the exhaust pipe is blocked, etc... These problems will generally have fault codes.

Please check if the meter is lit up. If there is, go to 4S to check the computer.

Also, check:

Whether the throttle is stuck on the tall foot pads, whether you are uphill when accelerating, whether you are on a plateau, and whether the gear is too high (for example, driving 30km h in 5th gear). Oh yes, let's see if the handbrake is raised.

In 15 years, Volkswagen Langxing started to add a little throttle speed on 3000 is normal, you are good dear, <> is not a normal amount, normal amount, the new car does not have it, the oil circuit has many impurities, large moisture, poor combustion, and has not been cleaned for a long time. If there is a great odor, you can use Si Youpu fuel additives to clean the oil circuit will be good, and the pipe will also become metallic, so private cars must also be cleaned. Long-term combustion is not good is carbon deposit, the exhaust pipe is black (direct injection car), the solution is very simple, the fuel tank plus the company has general additives, once clean the oil impurities tape and moisture, if the oil carbon deposition price is large, you can use it more once.

Summary. In this case, if it is lower than 1000 when starting, then this may be no cold start high rpm, this needs to be checked to see if there is a fault caused by the problem of the throttle data opening itself, resulting in no cold start idling, you can do a throttle reset to learn to deal with it to see if it is useful. Normally, such problems are mainly caused by the problem of throttle opening data.

Hello, I'm helping you sort out the answer to the question, please wait a while In this case, if it is lower than 1000 when starting, then this may be no cold start high rpm, this needs to be checked to see if it is a fault caused by a problem with the opening of its own throttle data, resulting in no cold start idling, you can do a throttle reset to learn to deal with it to see if it is useful. Normally, such problems are mainly caused by the problem of throttle opening data.

Summary. Hello, I am your exclusive technician, attentive, careful, and dedicated to answering your car questions, and finding corresponding problem solutions and solutions for you!

Based on your question, the following analysis was conducted.

The analysis scheme is as follows:

If it appears suddenly, this may be that you have not added gasoline well, I don't know if you have just finished filling gasoline, if you do not add gasoline, it is likely that your engine's ignition coil is broken, or the engine's oil pump is broken, in this case, you must test the fuel pressure of the engine, and check the ignition at the same time.

Solution: You can also restart it, if the car can walk slowly, you can drive to the repair shop for maintenance, if you can't drive, then you can only find a repair shop to rescue.

I hope my answer will be helpful to you.

What is the problem that the Langxing car suddenly can't be refueled while driving, and the engine is still shaking?

Hello, happy to answer your questions.

I hope my answer will be helpful to you.

It's been 4 months. Is it 4 months old for a new car, or is this problem 4 months old.

It has been 4 months and 70,000 kilometers.

It's fine.

Is gasoline pressure normal? Are there any fault codes?

Lavida car is a small displacement car, normal driving speed depends on the road conditions and the driver's driving habits, when the road conditions are complicated, will not step on the accelerator, when the road surface is good, it will not step on the accelerator to the end, because of the small displacement, the engine noise is also large when the accelerator is accelerated, and the fuel consumption is also large, and ordinary people will not drive like this. Therefore, the normal cheerful Lavida car is also the normal acceleration of Lavida.

Different from cruise control at high speed, the speed set by the driving computer cannot reach the speed when recovering, the computer command is full throttle acceleration, and the high-speed wind noise tire noise will mask the roar of some full throttle engines, so the driver will feel that the acceleration is fast and quite natural.

That's why the Lavida car accelerates differently in the problem. In fact, the full throttle acceleration is just as fast, but the full throttle is generally not used.

Langyi, you still want him to be fast, a 100,000 car can only be like this. I've been open for 8 years, and I've had a lot of small problems, so let's change to Japanese.

Look at how much speed to start asking, there are a lot of questions, operational problems? Mechanical problems? Electronics problems? It is advisable to find a professional to check it out.

1. It is very likely that the tire dynamic balance is needed, and the fault will disappear after it is done.

2. If it is the engine shake, there are more reasons, most of them are caused by fuel quality, especially the models with the rock T, the requirements for fuel are higher, if you add 93 oil for a long time, it is recommended to change two tanks of 97 oil to try it, you can also add some fuel additives to see if it can be alleviated.

3. Insufficient air intake, poor ignition and other reasons, such as the throttle valve is too dirty, the air filter has not been changed for a long time, and the spark plug does not jump the fire will produce the phenomenon of engine shaking, so it is recommended to go to the maintenance station for further inspection.

4. Sometimes, in addition to mechanical failures, the ECU (engine computer) will also cause failures when the opening parameters are set incorrectly, so it is best to do a computer test to see if there are any parameters that need to be adjusted, and whether the ECU needs to be upgraded.

There is too much carbon in the engine, resulting in a lack of power, and the carbon deposits need to be cleaned and the spark plugs checked.
