DSG Oil Cooler System

The Racingline Performance DSG Oil Cooler System is a complete, ready-to-install package designed for MQB Evo DQ381 gearboxes. It is an essential upgrade for any hard-driven 2.0 TSI vehicle running high power levels or operating in demanding, hot climates. Under aggressive driving conditions, the factory's integrated oil/water cooler can become overwhelmed. This leads to excessive oil temperatures, causing the oil to thin and degrade, compromising lubrication properties. The vehicle's DSG transmission may respond by reducing torque, increasing shift times, or even losing gear selection as a protective measure. This kit directly addresses these issues by introducing an auxiliary air/oil cooler mounted in the front airflow. This unit works in tandem with the factory oil/water cooling system, effectively doubling the cooling capacity when needed. A thermostat controls the flow to the additional cooler, opening only when oil temperatures rise above a specified threshold. The oil is then directed through the densely packed fins of the 10-row cooler, significantly reducing temperatures. This system is suitable for models equipped with the EA888 Gen4 Engine and DQ381 Gearbox, including a range of VW Golf 8 & 8.5 GTI/R/Clubsport, VW Arteon R, VW T-Roc R, VW Tiguan II models, VW Polo 6 GTI, Audi S3 8Y, Audi TT 45 TFSI, Audi SQ2, Cupra Leon, Cupra Ateca, Cupra Formentor, Skoda Octavia 4/4.5 vRS, and Skoda Superb III models from their respective 2020+ or 2021+ production years. Note that vehicles with the earlier EA888 Gen3 engine combined with a DQ381 gearbox require a different version of this cooler.
