Purpose and Function in the Oil Cooling System

The described pressure hose operates within the transmission oil circuit, connecting the automatic gearbox to the cooling components. It is responsible for:

• transporting oil under the correct pressure between the gearbox and the oil cooler,
• maintaining a stable operating temperature for the transmission,
• reducing the risk of overheating during city and highway driving.

By maintaining its original design, the hose ensures proper medium flow within the system, which is crucial for the durability of the automatic transmission.

Compatibility with Automatic Transmissions

This component is designed to work with automatic transmissions, where oil pressure and flow parameters are precisely matched to the gearbox's characteristics. Using the correct pressure hose allows for:

• maintaining correct oil pressure throughout the circuit,
• ensuring smooth gear changes,
• minimizing wear on internal gearbox components.

Selecting a hose that matches the system's design is particularly important in vehicles with an extensive transmission oil cooling system.

Benefits of Using an Original Audi Hose

Using an original oil hose from the Oil Coolers and Hoses group in an Audi offers several practical benefits:

• factory fit for mounting points and routing in the engine bay,
• maintaining the oil flow path designed by the manufacturer,
• reducing the risk of leaks resulting from improper fit of aftermarket alternatives,
• easier installation due to compatibility with original connectors and brackets.

This solution is particularly recommended for repairs where maintaining gearbox operating parameters close to factory levels is a priority.

Used Condition and Service Application

The hose is offered in used condition, allowing for an economical repair of the oil cooling system while maintaining the original design specifications. This type of component is suitable for situations where:

• a damaged or leaking hose needs replacement,
• a repair is being carried out after a collision in the oil cooler area,
• the oil circuit in an existing automatic transmission is being upgraded.

Choosing a used OEM part helps reduce service costs while maintaining proper flow and pressure parameters.
