DSG automatic transmission failures are caused by: malfunctions in the transmission's mechatronic control unit. In addition to offering the flexibility of a manual transmission and the comfort of an automatic transmission, the DSG provides uninterrupted power output, which is fundamentally different from two automatically controlled clutches. The DSG primarily consists of several major components: two basic 3-shaft 7-speed mechanical gearboxes, an electro-hydraulic clutch mechanism containing two sets of multi-plate clutch discs, and a gearbox ECU. Unlike conventional dual-shaft gearboxes or single input shaft systems, the DSG gearbox not only features dual clutches but also a coaxial dual input shaft system, with the 7 forward gears distributed on the respective driven shafts on both sides.

What causes abnormal noise when starting the car?

Reasons for abnormal noise when starting the car: 1. Pressure: The hydraulic tappet is worn or the system is depressurized. Under normal circumstances, the hydraulic tappet is always filled with a certain pressure of engine oil to ensure zero valve clearance, and the valve will not make noise during operation. 2. Lubrication: The lubrication system pressure is insufficient, and the pressure inside the hydraulic tappet is not enough to support the plunger, which increases the valve clearance, and the engine will produce a tapping sound of the valve during operation. 3. Severe wear: The hydraulic tappet is severely worn. When the car is parked for a long time, the oil in the hydraulic tappet leaks out. When the car is started for the first time, due to insufficient oil inside the hydraulic tappet, a tapping sound of the valve stem hitting occurs.

How often should the air conditioning system in a new Corolla be cleaned?

The new Corolla does not have a fixed cleaning interval for its air conditioning system. The cleaning frequency depends on the operating environment of the air conditioning system. The manufacturer recommends replacing the cabin air filter every 15,000 kilometers or 9 months for the Corolla. If there are no abnormal odors during normal operation, cleaning may not be necessary. Below is an introduction to the cabin air filter: 1. The cabin air filter primarily improves air cleanliness by filtering the air entering the vehicle interior from the outside. 2. The typical filtration targets include impurities in the air, such as fine particles, pollen, bacteria, industrial waste gases, and dust. 3. The purpose of the cabin air filter is to prevent these substances from entering the air conditioning system, thereby protecting the system, providing a good air environment for passengers, safeguarding their health, and preventing window fogging.
