[Daily unpacking] Beijing Volkswagen Scirocco car changes gears and does not move unpacking for maintenance

September 22, 2024

This is a project on gearbox disassembly and repair. Here are different processes for dismantling and repair car gearbox problems. I look forward to everyone’s reading and comments.
The car that came to the store for gearbox repair today was a 2010 Volkswagen Scirocco, a 2.0 TSI Sports version, equipped with a 6-speed dual clutch gearbox (DSG). According to the owner’s account: there is no reverse gear phenomenon, and occasionally the car does not move; the gearbox needs to be repaired.

(The sharp front face represents future design trends).

Kilometers traveled: 114352 kilometers. (Leather multi-function steering wheel with shift paddles)

Connect to the computer to detect the fault code: the gearbox shifting program is not trustworthy.

Opening test: (Prepare for maintenance)

Prepare to remove the power supply first;

The maintenance master is seriously dismantling;

The tires are being removed;

After being put on the shelves, picture of the chassis;

The electromechanical parts of the disassembled transmission housing and valve body;

The valve body is being prepared to be disassembled and repaired;

Prepare the disassembled valve body parts to replace the solenoid valve;

Removed cable;

Valve body assembly is completed;

disassembled clutch parts;

Damaged K1 return spring;

Comparison of replaced clutches;

Comparison of replaced front oil seals;

Replacement of original half-shaft oil seal;

Comparison of external filter replacement;

The gearbox is being assembled;

Assembly is completed;

After the installation was completed, the master finished the test run and the fault was cleared.
This gearbox unpacking maintenance mainly replaced the gearbox clutch parts, front oil seals, half shaft oil seals, inner and outer filter elements, and solenoid valves, and then cleaned the internal parts and reassembled them.
Friendly reminder: When the vehicle is in use, if the vehicle feels frustrated and locks up, in serious cases, it will lead to failures such as not moving, high fuel consumption, and poor shifting quality, which will directly affect traffic safety and threaten the safety of the driver and the passenger. Therefore, during the daily maintenance of the car, the safety issue of the automatic gearbox must not be ignored.
