Hello everyone, this is a column focusing on car repair and maintenance. There are car mysteries you don’t know, and it will teach you how to avoid the big pits on the road of car ownership. I believe that not only you but also many people have a certain sense of obscurity about the car aftermarket, which will help you uncover the unknown stories of car repair and maintenance.
In early 2017, Shanghai Volkswagen launched a new model, the Shanghai Volkswagen Tuguan L, based on the Tuguan platform. What is different from the old way view is that the L wheelbase of Tuguan has been lengthened by about 110mm, and the length of the car body has reached 4712 mm, which has directly entered the camp of medium and large SUV. As this kind of SUV, which directly lengthens the original model and becomes bigger, it can further reduce the development cost. But will consumers pay for it, which costs nearly 230000 yuan at the entry level?
The interior of Tuguan L is still somewhat different from that of Tuguan. You can see at a glance in the car that the edges and corners are more sharp. In recent years, the interior design trend of Volkswagen Group, from the previous sharp to the later round to the present sharp, is it a concept of going back to nature?
The chassis is always in the best place of Volkswagen, even on the guard plate. Tuguan L lower guard plate is very wrapped, in other words, it should be very airtight. There are several air intakes at the bottom of the guard, the main purpose of which is to dissipate heat to the engine and gearbox. In fact, many people will think that this kind of heat dissipation efficiency is low, but it is not. Many early engines rely on air cooling, such as the Porsche 911 356 model.
The interior of the engine compartment of Tuguan L is neat, but due to the characteristics of the EA888 itself, the upper surface of the engine is a bit messy.
At the bottom of the body of Tuguan L, I saw something unacceptable to Virgo, that is, the wax injection into the cavity of the anticorrosive coating had been crystallized and accumulated on the longitudinal beam. The steering rod of the half shaft is also wrapped in melted paraffin crystals. Even if it is a high-end brand, Audi will make it easy for you to understand where the oil leakage is caused.
The workmanship of Tuguan L is sincere, but it is still above Tuang. The drain pipe of the fuel tank is so directly exposed on the rear wheel supply, it is really direct and violent enough, and now I think Volkswagen is becoming more and more like an American brand.
This Tuguan L is a four-wheel drive model, and the rear axle differential is inevitable. In fact, for SUV, it is necessary to buy a four-wheel drive model. But at present, Tuguan L sales are mainly carried by two-wheel drive models. The first car owner’s understanding of the concept of the car is not enough, and the car is still very practical for the Chinese people. I will not repeat the difference between four-wheel drive and two-wheel drive here. Only those who have driven it will know how obvious its advantages are.
Gravity oil discharge method for oil discharge, the oil pan is as smooth and clean as new.
Oil bottom bolts have been completely reformed. In the application of Audi B9 engine oil pan design, plastic oil pan plastic bolts are a great test of service life. The picture in the lower left corner shows the painting confirmation of the oil bottom bolt after the installation of the oil bottom bolt. The significance is to reduce the embarrassing situation of bolts forgetting to fasten after construction, which is quite practical for the after-sales maintenance industry.
An oil filter element that has been disassembled.
The new oil filter element has been installed and is not from the original factory. Instead, it is produced by supporting manufacturers, from Sofima in Shanghai. This oil filter element has a high performance-to-price ratio and is well-known in China.
For a car that has traveled 10,000 kilometers, I saw a lot of residual oil on the filling port of the oil. Although I know that this will cause the oil to spill to other places when filling, but in the light of the current situation, I think there has been some slight oil leakage in this oil cap.
The oil filter element has been installed.
The engine oil is signed by Anso and the model is 5W30. This kind of engine oil is not suitable for use in Northeast China, mainly because the low temperature starting ability is poor and it is not easy to start. Because the low temperature resistance of engine oil is not strong enough, in the weather of more than 30 degrees below zero in the northeast, the cold start time will be very long, even can not catch fire. Friends in the northeast can choose 0w series of engine oil, but the price will also go up a part.
I saw my favorite rearview mirror on Tuguan L because it was so three-dimensional. In the past, I always thought that the rearview mirror of the public was extremely ugly, even a little twisted. Until I saw the rearview mirror of Tuguan L, I was really confused by its design.
