The engine oil has passed more than 4000 KM since the last oil change, and the last one is Foss GT1. It has been used since the warranty period. This time the oil change is three bottles (3L) Mobil FS+ and one bottle (1L) Jinmei.

Ps: in order to consume this bottle of gold and beauty, Tuben four Ace next door switched to Shell. It’s useless to keep it. This time we mix it together.

To get to the point: in order to solve the problem for one day, we will leave early this morning and officially leave at 8:34.

Let’s get to the point. This is the Auto repair Forum.

At 09:30 in the morning, the top door arrives at four aces.

For gasoline engines, carbon accumulation is inevitable, only when refueling, with additives to alleviate, if the continuous use of additives, fuel injection nozzles, cylinder, there will not be a large amount of carbon accumulation, can not be cleaned. However, there will still be carbon deposition in the intake port and intake valve, so use an endoscope regularly to see if the carbon deposition in the intake valve is black and thick. If the carbon deposit is obviously black and thick, it should be cleaned with walnut sand or dry ice, and the general auto parts store in the city costs only a few hundred yuan. The price of Si is 30% and 50%.
In the words of E altar: the best use of additives is small dose, continuous, life-long use.
Before you use gasoline additives, you must first use an endoscope to see if the carbon deposition is serious. If you see that the carbon deposition is obvious, you must first disassemble and clean the carbon deposition, and then take the additive before it can be effective. Carbon accumulation for a long time can not directly take additives, will pull the cylinder.
The most direct symptoms of carbon accumulation are lax intake valve closure, lack of cylinder pressure, inability to start or idle jitter.

This time, experience the new method of Volkswagen four Ace, ultrasonic cleaning.

Remove several other ignition coils and spark plugs, use endoscope to observe other cylinders, more or less the same, there is no way, must be washed, this time used a new scheme given to me by Volkswagen four Ace, using a new method called ultrasonic cleaning, lift the vehicle to release the old oil first

Reset the spark plug ignition coil and accessories. Remember here that the spark plug is tightened to 22 ±2N.m. The relevant tightening torque of the ignition coil has been marked in the following figure. I will not state them one by one.

At the same time, when the DQ200 gear oil is released on the other side, to replace the gear oil of this gearbox, it is necessary to release the oil at the oil discharge port of the gearbox oil, and tighten the oil release bolt with a torque wrench after the oil release is finished. When installing the oil discharge bolt, the tightening torque is 30N.m. After finishing the chassis work, put the vehicle down. Below the ABS pump is the vent of the gearbox. After loading the new gearbox gear oil into the container, use a conduit to add the gearbox gear oil from the vent. Remember to shake it before filling.

After sitting in the driver’s seat and adjusting the seat according to my daily sitting position, there is no big change in the space, and the ride comfort has increased, which should be due to the new seat design. In the sense of technology, it really feels a lot more advanced than my old model, and the position of the huge display screen is just right, so you don’t have to bow your head every time you switch navigation and tune songs. Volkswagen regular users, can be very skilled to drive directly, there is no strange feeling, after all, I saw that most of the cars in the exhibition hall are the same set of interiors, “set dolls” is Volkswagen’s ancestral skill

The improvement of the door is the greatest, the switch feeling is very light, and the sense of damping is just right. Compared with the old heavy door hinge, the new LAVIDA appears more elegant when opening and closing the door, and the driver believes that there is no need for a test drive. The combination of EA211 engine and DSG is still used. The EA211 1.4T engine is very abundant in A-class cars, and the DSG upgrade is fast and smooth. You have completed the shift unwittingly.

After watching the car from the exhibition hall, SA let me pay the bill, the man-hour of replacing the engine filter is 120 yuan, the man-hour of gearbox oil material is 300 yuan, and the price of carbon accumulation in cleaning is 464 yuan, a total of 884 yuan, and a bottle of additives is given as a gift.
