Do you need to replace the spark plug for Tiguan 20,000 km maintenance?

The 2012 Tiguan needs to maintain the cabin filter and spark plug when driving to 20,000 km. The 2012 Shanghai Volkswagen Tiguan is equipped with three engines, mated to a 6-speed manual or 6-speed automatic manual transmission. According to the official manual, the warranty period of the whole vehicle is two years or 60,000 kilometers (whichever comes first) is the same as the maintenance interval.

It recommends that the initial maintenance interval for Shanghai Volkswagen Tiguan models be 5,000 kilometers, and then regular maintenance will be required every 10,000 kilometers, including oil and filter changes. In addition, the air filter is replaced every 10,000 km; The first maintenance of the cabin air conditioning filter and spark plug is required when the vehicle has traveled to 20,000 km, after which it is recommended to replace it every 30,000 km; Gasoline filters and automatic transmission oil are changed every 60,000 km; The brake fluid is changed every 50,000 km or 2 years, whichever comes first. In terms of wearing parts, manufacturers provide a three-month or 10,000 km warranty for light bulbs, brake pads, clutch friction plates, spark plugs, filters, tires, wiper blades and other wearing parts.

Hello No, no.

However, the manufacturer requires that it be replaced for 30,000 kilometers.

The standard needs to be replaced, and it can be replaced for 40,000 kilometers.

Tiguan. The original factory used the double platinum spark plug early.

It can be replaced in 5 to 60,000 kilometers, but the 4S store will recommend replacing it in 20,000 kilometers.

When the spark plug needs to be replaced, it can be removed and checked to observe the gap between its color and the motor, and whether there is air leakage between the gap between the ceramic and the metal shell.

If you feel that it is inconvenient to remove it, you can also observe whether it is difficult to start the car in a cold situation, whether the idle speed is shaking, or whether you feel whether the engine performance has decreased significantly.

The service life of different spark plugs:

1. Ordinary resistance spark plug;

This kind of spark plug is the largest number of cars, because his economy is particularly high, we can read this kind of spark plug in about 100,000, and many models below, because his performance is stable, and ** cheap, Dr. This kind of spark plug purchase price is only about 10 yuan, and the most replaced is this kind of spark plug. Replacement mileage: about 30,000 km.

2. a platinum spark plug;

This kind of spark plug, due to the upgrade of metal material, can be said to greatly improve the service life of our spark plug, so that our spark plug ignition is more stable and reliable, after all, the more expensive *** is used, so the life of the spark plug is improved. Replacement mileage: about 60,000 km.

3. an iridium spark plug;

This type of spark plug is more reliable than platinum spark plugs, and the life of the spark plug is also improved, because the metal is better liquid, so its conductivity is better.

It is also better and able to produce stronger and more stable electric sparks, Nissan.

Many models are equipped with this kind of spark plug, and the replacement mileage: about 80,000 kilometers.

In 2010, the Tiguan drove to 57 kilometers, less than 8 kilometers from the last maintenance, and added oil once, about half a liter. I found that the dipstick was almost to the bottom line, and I felt that the sound of the engine was getting louder and louder. So I bought three filters (oil filter, air air filter, air air filter) and oil, and came to this shop that has been doing maintenance.

It should be said that the Tiguan needs to fill up 5 liters of fuel, and the oil does not reach the upper limit of the fuel meter. The premise is that after the old oil flows out naturally, the oil in the car should be sucked clean with a real empty oil can. The spark plug has been replaced.

The carbon collected by the raw and mountain-based is never cleaned. It's been two years since I bought my spark plugs. Every time I come here, I check the spark plugs.

Every time, the master said that it could be opened without changing. Said that it could be changed this time. This is the first time that the Tiguan has changed spark plugs.

Forgot to take a picture of the outer packaging of the new spark plug. Quadrupole. During the repair, I found that the shop had changed the brake fluid to carry out activities.

Because of the recent low-speed braking, there is always a whistling sound, so I checked the brake fluid and decided to switch to a Bosch one.

I used a machine, introduced new brake fluid into this machine, and changed all four positions together. Observation window and pressure gauge for monitoring. After changing the brake fluid, the whistling sound at low speeds, especially when starting and when stopping and applying the brakes, disappears!

What about the Volkswagen Tiguan? Volkswagen Tiguan modification, Volkswagen Tiguan maintenance million car purchase subsidy.

The replacement cycle of the fire and flower plug should be decided according to the actual use of the vehicle and the failure phenomenon of the vehicle.

The life of ordinary spark plugs is 40,000 km, and it is recommended not to exceed 40,000 km, otherwise the ignition efficiency will decrease, resulting in a decrease in engine power.

The life of a single platinum spark plug is 5-80,000 kilometers, which needs to be replaced regularly, and the single platinum spark plug can be reduced by normal anodic, cathodic ablation, ignition gap change, etc.

The life of iridium spark plugs is 50,000 km, and when the performance is reduced, it is manifested as cathodic ablation, resulting in ignition gap changes and reduced stability.

The life of iridium platinum spark plug is 8-100,000 kilometers, and the performance is usually manifested as the aging of the ceramic insulation part, and the phenomenon of air leakage leads to a decrease in cylinder pressure, insufficient power, and the fuel consumption is increased and the efficiency is worse.

The life of the double iridium spark plug is theoretically more than 100,000 kilometers, and it is the best performance spark plug at present.

Tiguan spark plugs are replaced every 35,000 km or 48 months. The spark plug, commonly known as the burner, is used to release pulsed high-voltage electricity from the high-voltage line, break through the air between the two electrodes of the spark plug, and generate an electric spark to point the mixed gas in the gas cylinder.

There are hundreds of models of spark plugs, but one standard spark plug cannot be used on all types of engines. Due to the different operating characteristics of various engines, there is no one standard spark plug that can be adapted to all engines. Therefore, it is necessary to choose the right spark plug according to the characteristics of the engine.

Instructions for use of spark plugs:1. Regular replacement of resistive spark plugs is an important part of an automotive engine's ignition system.

All gasoline engines have spark plugs, one per cylinder, and some high-speed gasoline engines also have two spark plugs per cylinder. 2. Confirm the timing of spark plug replacementExperts said that whether the spark plug needs to be replaced, remove it and check it to see if there is a burning color, the gap between the electrodes, whether the gap between the porcelain bottle and the metal shell is leaking, etc. In addition, he also said that if the owner finds that the car is cold and difficult to start, there is obvious stuttering, idle shaking when driving, or the engine acceleration performance is reduced, the spark plug should be checked in time.

Because once the vehicle shows the above performance, it may be caused by the aging of the spark.

Volkswagen Tiguan Platinum Iridium spark plugs have a service life of 5-70,000 km. Usually the same is true for vehicle maintenance manuals, which stipulate replacement intervals. It is not the ultimate life cycle of the spark plug, it represents the optimal performance cycle of the spark plug.

Therefore, many veteran drivers always have spark plugs in their toolbox so that they can be replaced at any time. The replacement steps are;

1. Prepare the tools

First of all, we need to prepare the tools for replacing the spark plug: quick trigger and sleeve, the sleeve model we need to replace is 16mm and 8mm, other models may have some different models, but as long as you can find the sleeve model with the screws unscrewed.

Some models also have a plastic hood on the engine, to remove the hood, you have to see what type of screw is on your car, generally only a Phillips screwdriver can be removed.

2. Unscrew the pile head of the high-voltage line

Clean the dust and oil near the pile head of the high-voltage line, and then unscrew the fixing screws of the pile head of the high-voltage line with a sleeve. Some high-voltage line pile heads may be tight, if this is the case, you need to shake up and down left and right to operate slowly, otherwise it is easy to pull off the high-voltage line.

After removing the pile head of the high-voltage line, loosen the spark plug with a sleeve, be careful not to let dust enter the combustion chamber, and keep it clean, dry and oil-free, otherwise it will cause leakage, spark weakening and other faults.

3. Twist outSpark plugs

After unscrewing out the spark plug, you can see the usual working condition of your spark plug, as shown in the figure below the two spark plugs, the left is brand new and unused, and the right is used after 40,000 kilometers.

Four, installationSpark plugs

When installing, first align the spark plug with the socket to the screw hole, gently screw it in by hand, screw it to about half of the total length of the thread, and then tighten it with the sleeve. After installing the spark plug, if you use an ordinary sleeve to tighten it without a torque wrench, you don't need to tighten it again as long as it feels tight, otherwise it is easy to screw the screw.

In fact, whether the spark plug needs to be replaced, remove it and check it to see if the color of the burning, the gap between the electrodes, the gap between the porcelain and the metal shell, etc. If you find it difficult to start the car in a cold state, there is obvious frustration when driving, idle shaking, or the engine acceleration performance is reduced, you should check the spark plugs in time. Because once the vehicle has the above performance, it may be caused by the aging of the spark plug.
