What is the problem of Audi Q5 cold car starting the water temperature light and turning on the red

The height of the coolant level is too low, and the cold car is checked.

If you notice significant body shaking when starting or stopping the vehicle without turning off the engine, it may mean that the vehicle has one of the following three conditions:

1.The engine has a lot of carbon deposits.

The most common cause of car shake is a dirty throttle or excessive carbon build-up in the fuel injector. When the carbon deposition inside the engine is excessive, the gasoline sprayed by the cold start fuel injector will be absorbed by the carbon deposition in large quantities, resulting in the mixture of cold start being too thin, making it difficult to start, in this case, only when the gasoline absorbed by carbon deposition is saturated, it is easy to get on the car, and the gasoline adsorbed on the carbon deposition after the car will be sucked into the cylinder by the vacuum suction of the engine for combustion, and the mixture becomes thick, and the combustible mixture of the engine is dilute and thick, causing idle shaking after cold start. The lower the temperature, the greater the amount of oil required for the cold start, and the more carbon deposits will affect the smooth cold start.

Solution: Clean the oil circuit and check whether the idle motor has carbon deposits and should be cleaned.

2.Problems with the ignition system.

Check the working condition of the spark plug, high-voltage wire and ignition coil, the ignition system is not working well, and the spark plug tripping condition is not good, which will also lead to this kind of failure.

Solution: Check whether the spark plug has too much carbon deposit, and replace the spark plug.

3.The oil pressure is unstable.

If you have cleaned the engine carbon deposit, washed the throttle, changed the oil pad and spark plug, etc., and still found that the body shakes when idling, it is recommended that you go to the 4S shop to check whether the fuel supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is abnormal or the intake pressure sensor value is wrong and the work is not good, the body shake will be triggered.

Solution: Check the oil pressure and replace the parts if necessary.

4. Aging of engine parts.

Car jitter is also related to the aging of the engine feet (also known as claw pads). The engine foot is actually the suspension system of the engine, and the engine foot is responsible for absorbing the subtle shake of the engine when it is running, and if there is a problem with the engine foot, these vibrations will be transmitted to the steering wheel and cab, causing shaking when idling.

Workaround: Replace the parts.

The reason why the new Audi car with more than 1,000 kilometers has a yellow fault light.

I went to the 4S store to detect that it was an occasional sensor failure, and it was manually eliminated. More than 3,000 kilometers of yellow lights are on again, what is the situation, is it normal? Or do you want to change the sensor? The store suspected that it was a problem with the oil and had been refueling at Sinopec.

It has nothing to do with the sensor, the sensor can detect the fault and light up, indicating that everything is normal with the sensor, and why is it lit at 1000 kilometers, and it is on before, mainly because the sensor works with a cumulative data overlay mechanism, that is, the fault light will be lit after the data of bad emissions is accumulated to a certain number of times. The biggest variable within 1000 kilometers is fuel, and it can also be said that within 1000 kilometers, the quality of the initial fuel is probable. For example, when the car manufacturer leaves the factory, the initial fuel is added, which is used to move the vehicle, but the car is less than half a month in the owner's hands, so the probability of fuel deterioration is very high.

In addition, the store should also replenish some fuel for the new car, and the barrel containing the fuel is also oxidized and not cleaned, so there will be a large gum or a large oil fungus in the fuel tank, which will constantly pollute the new fuel, resulting in no fresh fuel to use in the entire oil circuit.

This kind of situation will also happen in the previous China 4 5 models, but because the sensor has very low requirements for environmental protection, it has little impact, and the naturally aspirated EFI engine does not have high requirements for the mixture, so even if it happens, our fault light does not show. But that doesn't mean it didn't happen.

So why some new cars also turn on the fault lights and run away, which is related to the speed of each car using fuel, often the faster the use, the smaller the impact, because after several times of fresh fuel will dilute these substances, but for most car owners, the vehicle is not used much, so it creates convenient conditions for the deterioration of the oil circuit.

At present, new domestic joint venture cars, domestic cars, and imported cars will encounter such problems, after encountering, do not expect fuel to clean fuel, need to use effective detergents to decompose and burn to discharge these undesirable substances, it is recommended to use some additives with general stock solution, clean 2 times, open more, after the fuel tank oil circuit is clean, the combustion becomes better, the emission index is restored, and the emission fault lamp will disappear.

This kind of situation has been encountered before, do not go to replace the parts, the original car parts are of the best quality, better than the quality of the original parts in the later stage, and do not consider the problem of the sensor, the problematic sensor will not detect the fault lamp. Don't think that there will be no problem with fuel, car companies will have such a defective rate of precision production, not to mention the fuel industry, is it 100% yield, impossible. Apple mobile phones have after-sales service, is it 100% good for big fuel companies?

So I took a big detour before, changed a lot of accessories, and finally cleaned the oil circuit 3 times in a row according to the method of the circle of car friends, and the slight shaking of idle speed also disappeared.

The engine fault light is on, which is usually caused by fuel problems. If you have recently refueled or changed the fuel label at a small gas station, if so, it may be a fuel problem, if there is no substantial problem with the vehicle, you can continue to drive for a while. At the same time, the occasional alarm prompt disappears after restarting, so you don't have to worry about it, and there will be false alarms in the self-test of electronic equipment.

If it is a constant after each start, it should be taken seriously, and it must go to 4s to read the fault ** and find the cause, after all, the engine is no trivial matter.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

If the engine fault light of the new car is on, it means that the engine is faulty. It may be that the engine burns badly, or a sensor is not working properly, or there is a problem with the spark plug, there is a problem with the ignition coil or there is a problem with the control computer.

Question: The new car you just mentioned.

The answer in this case is to say that this specific needs to be tested by the computer, this is a warranty, you can go directly to the four S shop, if it is the quality of the vehicle, you can ask him to repair it for free.

Audi Q5 after parking, sometimes the double flashing lights keep flashing, the biggest possibility is that you use the key to lock the car, and then inadvertently press the remote control lock button, this is fine. When the double flash light is used, it is:

1. Driving in foggy days, due to poor sight in foggy days, you should not only turn on the double flashing lights, but also turn on the fog lights to remind the attention of passing vehicles and illuminate yourself.

2. In the event of a breakdown on the road or a traffic accident, the double flashing lights should be turned on to remind passing vehicles to pay attention to safety. After the vehicle breaks down or stops in an accident on the highway, the use of lights and warning signs are not in accordance with the regulations, 12 points will be deducted at a time.

3. When towing a faulty motor vehicle, both the towing vehicle and the towed vehicle should turn on the hazard warning flashing lights to remind their cars to be in an abnormal state.

4. When temporarily parking on the roadway, turn on the double flashing lights to remind other cars to pay attention.

5. When forming a convoy allowed by the traffic police department, the vehicles in the convoy should turn on the double flashing lights.

Anti-theft device sensitivity: If the sensitivity of the immobilizer is too high, a slight vibration of the car will cause an alarm and double flashing lights. In that case, it can be handled according to the sensitivity of the anti-theft server; Start by looking for the immobilizer server on the rain shield directly under the steering wheel and directly under the A-pillar, and then adjust the sensitivity button.

If the power switch is loose, when the car is vibrate, it will cause the power switch to appear on the touch screen, and then the power circuit will be connected to cause the double flashing light, at this time, you only need to replace the power switch.

Fault cause 1: The door is not completely closed.

After the vehicle enters the anti-theft mode, the door will trigger the anti-theft system alarm and open the double flash to remind the owner when the door is not completely closed.

Solution 1: Use the car key to remove the anti-theft system, open the door and close it again, and the owner can operate it by himself.

Cause of failure 2: There are people or animals in the car.

After the vehicle is locked, there are passengers or pets left in the cabin, and the gravity sensor in the seat will trigger the alarm of the vehicle anti-theft system when pressurized, and the double flashing lights will be illuminated.

Solution 2: The car owner can use the car key to disarm the vehicle anti-theft system. If the vehicle is parked for a long time, please do not leave passengers and pets in the vehicle to prevent triggering the vehicle anti-theft system.

Cause 3: The car key is damaged.

After the internal chip of the car key is damaged, the keyless entry function of the vehicle fails. At this time, the owner uses the mechanical key to open the door, and the anti-theft system will mistakenly think that the vehicle has been illegally invaded, and then trigger the system alarm.

Solution 3: Use a spare car key to remove the vehicle anti-theft system, and then go to the 4S store to detect the damage to the chip inside the car key. If it is not caused by human reasons, the vehicle can be replaced free of charge in the 4S store during the warranty period; If the vehicle exceeds the warranty period, the cost of replacing the car key in the 4S shop is about 1500-2500 yuan, and the cost of replacing the car key in the repair shop is about 1500 yuan.

Is there something in the car that is swaying by solar energy, open the left door, and there is a button on the left side of the door.

I don't know, but give some advice, first wash the car to rule out external causes, and if it still rings, check the line or the central control computer to see if there is an error in the computer program.

If there is water in the car or there is a problem with the control unit, if you have not installed additional equipment, it is best to put the car in a 4S shop for a thorough overhaul.

Stop the car for no reason, and the horn will sound What's going on, I advise everyone to be cautious when buying a car.

Is your car solved? My car is always like this, and I went to the 4S shop and said it was no problem.

Or if you have installed a one-button start function in this Q5, it may be a problem with one-button start.

I believe that many car owners will encounter Audi Q5 engine fault light on such a small car problem, so the following will introduce you to the Audi Q5 engine fault light on the solution to this problem, I hope to help you solve the problem. First of all, it can be said that there are several reasons why the engine failure light is on:

First, because the fuel quality is poor, the combustion state is not good, and the engine fault light is on;

Secondly, due to the failure of the electronic control system or some mechanical parts of the engine, the normal operation of the engine cannot be guaranteed, such as damage to the spark plugs, sensors, actuators and even the engine control unit, which will cause the vehicle to fail to accelerate, causing the engine failure light to turn on;

Thirdly, the cylinders inside the vehicle's engine are dirty or have a lot of carbon deposits. Carbon deposition has strong adsorption, which will adsorb fuel particles in the mixture, affect the normal operation of the engine, and then cause the engine failure light to be on.

Generally, when the engine light is on, you can first add the fuel additives recommended by the manufacturer or replace the fuel to discharge the fuel problem. If the fault persists, you can try cleaning the engine intake system again. If the engine fault light is still on after the above two reasons have been ruled out, it means that the vehicle is likely to have an engine fault and needs to be monitored and repaired at the workshop.

For a particular fault, you should decode the fault with a special diagnostic instrument before you can check it. According to the analysis of the cause of the failure, the faulty parts can be replaced, so as to restore the normal working state of the motor.
