Does it affect the Jetta sometimes to 4,000 revolutions during the run in period?

Occasionally, this speed will not be sometimes, and the control point will be as much as possible within 3000km, which is better in the long run, and there is no need to worry about it.

You need to pay attention to the following points during the run-in period of a new car:1The engine speed should not be too high, preferably not more than 3000 rpm.

2.There should be a process of warming up the car during the cold start, and driving on the road after the water temperature changes, generally about 5 minutes. 3.

The load must be reduced according to the load regulations of the model, and it is advisable not to exceed 70% of the specified load capacity. 4.The impact damage of the sudden braking to the engine, braking system and chassis of the new car is very large, and the situation should be dealt with in advance during driving, and the deceleration and gear reduction should be reduced.

5.Avoid sudden refueling and braking, and try to maintain a constant speed. The maximum speed within 2000 kilometers should not exceed 90 kilometers per hour, but it is not possible to drive at low speed for a long time.

6.According to the time and mileage specified by the manufacturer, go to the 4S shop on time to do the first oil change.

Yes. During the run-in period of the new car, the engine speed should generally not exceed 3000 rpm, the maximum speed should not exceed 90 kilometers per hour, the occupants should not exceed 3 adults (including the driver), and the continuous driving should not exceed 2 hours. FYI: Please set to .

Occasionally, it doesn't matter, the number of revolutions during the run-in period exceeds 2500, and the speed exceeds 80Don't accelerate sharply, brake suddenly, thank you.

Hello, once or twice once in a while is no problem, don't often rotate at high speeds, which is not conducive to the normal run-in of the vehicle!

1: Do not exceed 60 miles during the run-in period. (Just don't exceed a speed of 60 kilometers per hour).

2: When running to 2300 kilometers, you must go to maintenance, which is very important, the first time to change the oil and gear oil have the fine iron pins that have been run-in, not to change the engine is damaged. In the future, every 5000 a total of six to change the oil and three cores.

It will be easy to use after a period of running-in.

3: Do not drive at a single speed for a long time; Then don't add any metal anti-wear agents.

4: Start in low gear, and the water temperature should be controlled at 80 to 90 degrees Celsius. Shift gears in time during the journey, and don't use one gear for a long time, which is not conducive to the running-in of each gear. It is also not possible to drive at low speeds in high gear or at high speeds in low gear.

5: After the car starts, it should be heated in situ, and then start after the water temperature reaches the starting temperature. When driving, choose a good road surface, keep driving at a moderate speed, keep the throttle small, and try to avoid rapid acceleration and sudden braking.

6: Don't help others tow the car, the tow truck has all kinds of harm but no benefit.

7: Don't use idle speed to warm up the engine. The current EFI engine has a temperature compensation control system, which can meet the normal driving of the vehicle in the cold state.

If the EFI engine is preheated for a long time, it will only increase fuel consumption invisibly. After the car starts, it should be heated in situ, and the water temperature should reach the starting temperature before starting. When driving, choose a good road surface, keep driving at a moderate speed, keep the throttle small, and try to avoid rapid acceleration and sudden braking.

8: Don't drive the engine at high speed while driving. There are speed regulations for the initial driving stage of new cars, which are generally stipulated to be within 60 kilometers per hour. Generally speaking, the engine speed during the break-in period should be strictly between 2000-3000 rpm.

9: To avoid overloading the engine. The new car is easy to cause damage to the parts when it runs at full load, so it cannot exceed 75%-80% of the rated load during the running-in period.

These aspects are all issues that need to be paid attention to for novices on the road. Don't help someone else tow a truck, towing can do more harm than good.

10: Do not easily replace the original car engine oil during the run-in period, and always check whether the oil, coolant, battery, and electrolyte are sufficient.

11: The tires should be replaced backward and backward every 20,000 kilometers.

1. The engine speed does not exceed 3000 rpm.

2. It is best not to have a load for the first 500 kilometers.

3. Try to keep the car in a labor-saving state and shift gears in advance.

The run-in period of the general car is 3000 to 5000 kilometers, do not overload during the run-in period, do not overload the engine, do not rotate too high, do not high-speed low-gear, low-speed high-end, shift gears when the engine is 2000 rpm, so that it is not only fuel-efficient, but also the loss of the car is small, except for their own gears, do not exceed 100 kilometers per hour!

The run-in period does not only refer to the engine run-in, but the run-in of the whole vehicle, the engine has been run-in when it leaves the factory, but don't drive too fast, because there is no sports run-in between the engine and the gearbox!

There is also a run-in between the suspension, tires, and brake pads!

After the new car comes down, it is necessary to check whether the engine oil is sufficient, warm up the car when driving in the morning, do not step on the accelerator when the car is warm, and naturally warm up the car after starting, and the time is appropriate for one minute.

Due to processing and assembly errors, the frictional resistance of the moving parts of the new car is always much greater than normal when it starts to run, and the running-in (also known as walking) effect in the early stage of the car will have a great impact on the service life, working reliability and economy of the car. Therefore, the run-in regulations must be strictly implemented when using new cars.

1. Run-in regulations for new cars within 1000 kilometers:

1) Never drive at full speed.

2) - Generally not to drive at a speed of more than 100 km/h.

3) Avoid driving at high speeds in all gears.

2) The run-in of the vehicle between 1,000 and 15,000 km: it can be gradually increased to the maximum speed or at the maximum permissible speed of the engine.

2. After the run-in period, attention should be paid to:

1) When driving a car with a tachometer and shifting into the approaching high speed, the maximum engine speed allowed for a short time is 5 500 rpm when the pointer reaches the red indication zone at the latest. The maximum permissible speed in each gear is 40 kmh in the first gear, 65 kmh in the second gear, 100 kmh in the third gear, 135 km/h in the fourth gear, and 165 kmh in the fifth gear.

2) Avoid running the engine at unnecessarily high revs, and switch to high gear early to save fuel and reduce noise.

3) Do not drive the engine speed too low, and only change to low gear when the engine is working hard.

4) The speeds and rotational speeds listed in the instructions are only applicable to engines with normal temperatures. When driving cold, do not allow the engine to work at the highest revs, whether in neutral or in other gears.

5) New tires don't have optimal adhesion when they start with use, so new tires also need to be walked, slower for the first 100 km, and driven with care.

6) The new brake friction plate also needs to be run-in, in the first 200 kilometers of driving, there is not yet the ideal friction, if the braking effect is slightly worse at this stage, the pressure of the pedal can be appropriately increased. The same applies after each subsequent replacement of the brake pads.

7) Under possible conditions, the new car should avoid continuous driving for a long time during the run-in period, so as to avoid the engine and chassis parts continue to work for too long, resulting in the aggravation of the wear of the parts, and directly affect the service life of the car. Also avoid running at full load, generally in the first 1000 kilometers of driving, it is best to run below 80% of the rated load. Also, try to avoid driving at high speeds, and don't go faster than 70% of the top speed with the throttle open for the first 2,000 km/h.

8) during the run-in of the new car, the driver should heat up in situ after the new car starts at the beginning, and then start after the water temperature rises to the working temperature range, and should choose a good road surface during driving, and slow down when the road condition is poor; When driving, the throttle should be smaller, the operation should be light, once the engine or chassis sound is found to be abnormal, it should be stopped to check the fault in the embryonic period.

When the outdoor temperature is high, the speed of starting the ignition speed is slow. This problem should belong to the calculation method of the control program of the electronic control unit, at this time, if you continue to drive the vehicle to the water temperature is normal for 10 minutes, please observe the idle speed again, as long as it can return to the range of about 800 rpm, it is a normal phenomenon, and no special treatment is required.

The working mode set by the initial detection sensor data of the engine determines the control speed of the idle speed of the cold car, because the temperature has risen 3 4 minutes after the engine starts, at this time the engine is turned off and re-self-tested, and the engine controls the idle speed under different conditions, which is completely possible to be different from the idle speed controlled before the ignition.

The initial suspicion is that the "oxygen sensor" has a feeling of slow refueling, if there is, but it may also be caused by the dirty throttle, but most of the Jetta partners are like this, and it is said that this batch of cars is not assembly line, but assembled in parts, so there is a common problem.

The step is to clean the throttle – make a match – and see the feedback from the oxygen sensor. (If it doesn't work, there's really no way).

In relation to temperature, check the "water temperature sensor" first, due to the high outdoor temperature at 20-30 conditions.

The engine idles a little higher when it's cold than when it's hot, so the engine can start.

The idle speed of the engine is controlled by the water temperature sensor and the intake air temperature when the engine is cold.

This is because the ECU of the car computer controls the amount of fuel injected through the water temperature sensor when the car is cold.

When the car is cold, the amount of fuel injected is large, and the mixture is thicker, so it is easy to start.

If you don't check it well, maybe there is a possibility.

The idle switch does not close".

Fault analysis: When the idle contact is disconnected, the ECU determines that the engine is under partial load. In this case, the ECU determines the amount of fuel injected based on the air flow meter and the crankshaft speed signal.

At this time, the engine is working under idle condition, and the air intake is small, resulting in an over-concentrated mixture and an increase in speed. When the ECU receives the "mixture is too thick" signal from the oxygen sensor, it reduces the amount of fuel injected and increases the opening of the idle control valve, which causes the mixture to be too thin. Reduces the rotational speed.

When the ECU receives the signal of "the mixture is too thin" fed back by the oxygen sensor, it increases the amount of fuel injected and reduces the opening of the idle control valve, which causes the mixture to be too concentrated and the speed increases. This repeatedly makes the engine idle unstable, and turning on the air conditioner, steering wheel, and headlights at idle will increase the load on the engine. In order to prevent the engine from stalling due to increased load, the ECU will increase the amount of fuel injected to maintain the smooth operation of the engine.

When the idle contact is disconnected, the ECU thinks that the engine is not in idle condition, so it will increase the amount of fuel injected a little, so the speed does not increase.

Diagnosis method: Turn on the air conditioner and turn on the steering wheel when idling The engine speed does not rise, which can prove to be this fault.

Troubleshooting: Adjust, repair, or replace the throttle position sensor.

Clean the throttle idle motor, if it doesn't work, just change the idle motor to try.

It's an electronic throttle, you go to the Volkswagen service station to do a matching initialization, and there should be no problem!

For the problem of high fuel consumption of the new car, the new car is more fuel-efficient during the run-in period, because the various parts of the new car are tightly matched, so the power of the engine can not be fully played, and eventually the fuel consumption of the new car will be high. If you drive at low speed in the city for a long time, there will definitely be high fuel consumption, and the use of vehicles is easy to form carbon deposits, you had better find time to run at the end of the run-in period, because the high speed can be extremely rough to make the engine computer record and store the engine high-speed crack operation of the data, so that the engine can be normal in the future, in terms of speed and fuel saving, I hope mine will be helpful to you.
