Turbocharger Cooling Line / Turbine Water Pipe – 06M145144E

Original turbocharger cooling system circulation pipe (semi-rigid coolant supply or return line for the turbine housing), designed for Audi A7 Sportback (4K / 4K8 generation) and Audi A6 C8 (type 4K2 / 4K5 / 4KA) with 3.0 V6 TFSI turbocharged petrol engines (55 TFSI designation / EA839 family / DLZA, DKMB, and related codes), as well as related models based on the MLBevo modular platform.

Original VAG cooling and turbocharging system component. Made of precision-formed aluminum alloy pipes connected by a high-pressure, reinforced elastomer coupling with factory crimp sleeves. Equipped with double-sided aluminum mounting flanges with mounting bolt holes and O-ring grooves. Operates directly in the cylinder bank ("hot-V") at the turbocharger housing. It ensures the safe flow of coolant through the turbine water jacket, protecting the bearing assembly from overheating and seizing, while the flexible center section effectively compensates for engine vibrations and thermal stresses.

Fitment guarantee and VIN verification

Every pipe undergoes mounting flange geometry verification, obstruction check, and pressure leak test before shipping.

Fitment / installation tip: The 06M prefix and 145 group indicate turbocharging accessories for EA839 V6 units. Using the original OEM pipe guarantees precise flange spacing without causing dangerous stresses on the turbine housing. Before installation, new heat-resistant sealing O-rings (Viton/FKM) must be installed and lubricated with coolant before tightening. Before purchase, we recommend comparing the full OE number with the suffix (E) on the pipe housing or verifying it using the vehicle's VIN.
