Where is the throttle valve of the Volkswagen Tiguan dismantled

Under normal circumstances, it is replaced every 50,000 kilometers or every 3 years. Steps to replace the throttle: 1. Exhaust:

Open the engine compartment and slowly unscrew the expansion kettle lid to expel the air from the cooling system in preparation for the later removal of the pre-hot water pipe on the throttle. 2. Disassemble the air filter box assembly: open the co-pilot seat, remove the screws that fix the air box assembly with ten T, and then loosen the buckle connecting the intake bellows and the throttle with a cross lift, dial the bellows, and take out the air box assembly.

3. Pull out the wiring harness and throttle wiring: remove the idle motor sensor and throttle position sensor plug on the throttle, and remove the throttle wiring on the throttle at the same time. 4. Dismantle the throttle:

Use pliers to remove the two water pipe clamps on the throttle first, and then use 10t to remove the four screws on the throttle, and use pliers to unplug the water pipe and remove the old throttle. 5. Install a new throttle: After removing the water pipe, immediately install it on the new throttle, reduce the outflow of antifreeze as much as possible, use pliers to jam the water pipe, install the four screws that fix the throttle, install the throttle wiring, and plug it in.

6. Match with special equipment: Now the car should be matched after replacing the throttle, and all the adaptive values should be reset to zero with special equipment, the computer memory should be cleared, the matching was successful, the air box assembly was installed, the test was normal, and the throttle was successfully replaced.

The Volkswagen Tiguan throttle removal method is as follows;

There will be a plug next to the throttle that needs to be removed before the throttle can be removed. For vehicles that do not often remove the plug, the plug may be relatively tight and difficult to remove, at this time we can use a small screwdriver to pry around the plug, and it is easy to remove it after the whole is loose.

After removing the plug, the next step is to remove the throttle. The throttle is usually fixed with 4 screws, the upper two screws are easier to remove, and the lower screws are a little awkward. We recommend disassembling the two screws that are difficult to remove first, so as not to increase the difficulty of removing the lower screws due to the shaking of the throttle valve when they are finally disassembled because the upper screws have been removed and not fixed.

In our experience, here we only need to loosen the screws with the help of tools, and then it will be more convenient to remove the screws by hand, but be careful that the screws fall in the cabin.

After the 4 screws are removed, the throttle can be removed, and the exposed pipe is the intake channel. As you can see from the picture below, there is obviously a lot of black carbon deposits in the air intake of our demonstration car, but we will talk about its cleaning in the future. Here we remind you that after removing the throttle valve, it is best to cover the entrance of the air intake with newspapers and other objects to prevent debris from entering.

After taking off the throttle, it is much more convenient to observe, we turn to the back to see, the dirt inside the throttle is still a lot of silver, especially the corners, the position near the shaft is a dead corner that hides dirt and dirt, if it is not removed, it is difficult to completely remove it, so if you clean it in a professional store, you must ask the staff to clean and blind after dismantling.

The Volkswagen Tiguan valve cover can be removed by using a sleeve to remove the set screws and then remove the valve cover. Attention should be paid to the disassembly and assembly of the valve chamber cover, the screws need to be disassembled and assembled in a certain order, and the glue should be paid attention to during installation, and the removal of the valve chamber cover needs to be carried out under the condition that the engine is completely cooled. The symptoms of car valve damage are as follows:

1. It will affect the working efficiency of the engine, and the power of the car will be reduced;

2. The shovel is abnormal, the engine will be unstable or unstable in acceleration during operation, and the overtaking performance will also be reduced, which will also lead to difficulty in starting the engine, and the phenomenon of not igniting will occur, and the car will also have air leakage or increased carbon deposits;

3. If the valve is broken, it will lead to unstable cylinder work, and unstable cylinder will cause the engine to shake, the engine will work weakly, and it will also lead to the blockage of the exhaust pipe, and in serious cases, it will also lead to black smoke.

Volkswagen Tiguan throttle is teasing under normal conditions, and the 4S store will recommend that the owner clean about 20,000 kilometers. Of course, different road conditions are different, and some cars tend to get dirty with the throttle. In serious cases, it is not uncommon for them to need to clean seven or eight thousand kilometers.

If you clean the throttle yourself, the ** of the cleaning agent can range from tens of dollars to tens of dollars. Generally, a bottle can be washed about twice. If the cleaning ** of the Sunguo repair shop or 4S shop exceeds 100, the owner can clean the throttle by himself.

Before cleaning the Volkswagen Tiguan throttle, put on gloves, install a cleaning spray nozzle, and aim the inside of the throttle to spray. This kind of cleaning agent is available on the Internet or in auto parts cities, ranging from tens of yuan to dozens of yuan. In order to check the effect of the code chain cleaning, we first sprayed it on the throttle side.

It will be cleaner to spray a little in the throttle. It is recommended to face the trash can when washing, because the carbon deposits will liquefy and flow down at the same time as splashing, which is easy to pollute the environment. Moreover, the cleaning agent has a certain pungent smell, so it is best to wear a mask when operating and keep it away from the mouth, nose and eyes.

Once all is in place, wipe with a cotton cloth. In order to wipe more thoroughly, you can take off the gloves and wipe the inside of the throttle with a cotton cloth directly with your hands. Although the cleaning agent will be corrosive, it is okay to contact it for a short time, so we only need to wash our hands in time after washing.
