RacingLine DSG Oil Cooler Kit (DQ250 6 Speed)

It's not just your engine oil that you need to protect. Transferring more power and torque through the DSG gearbox generates ever more heat to dissipate. Significantly increased oil temperatures means only one thing: a decrease in the ability for your DSG box to stay properly cooled, eventually causing power drop and gear selection issues.

RacingLine’s unique DSG Oil Cooler Kit is an essential fit for any hard-driven MQB 2.0 TSI car running high power levels or in hot climates. It's a complete ready to install package, using a clever sandwich plate design for straightforward and completely reliable installation.

Under hard driving, the factory DSG oil/water cooler is easily overwhelmed. Problems start to occur when oil cannot dissipate its collected heat fast enough and the oil begins to thin and degrade - losing its lubrication properties.

When this happens, the DSG will protect itself and begin to lower the torque, increase shift times and in extreme circumstances even loose gear selection. Many track drivers have experienced this frustration.

The RacingLine kit solves this problem: by adding in an additional air/oil cooler positioned right in the airflow at the front of the car, oil temperatures are reduced by around 60° - 70° degrees Fahrenheit (of course dependent on how the car is being used, ambient temps and state of tune).

RacingLine’s solution uses a clever design which retains the original factory oil/water cooling and adds to it with the thermostatically-controlled front-mounted cooler - doubling up your cooling capability when it's needed with less heat transfer into the water system.

The DSG oil will still quickly warm up just as quickly from the hot water in the engine's coolant system, reaching full operating temperature as soon as possible.

But that's where the problem begins on a hard-driven car. The hot engine coolant will now have little to no cooling effect on the DSG oil, and gearbox temps start to rise rapidly.

The unique adaptor block oil take-off features a smart internal thermostatic-control valve to direct oil flow through to the cooler only when temperature hits 82°c/180°F. Oil temperature then drops quickly and significantly as it is pumped through the densely packed fins of the 10-row cooler’s large surface area mounted right in the cool airflow.

After the cooled transmission oil returns from the cooler, it carries less heat to be absorbed into the engine coolant system – helping control all your temperatures under the hood.

As you’d expect, the RacingLine DSG Oil Cooler is a beautifully detailed complete kit, cleverly thought-out and packed with thoughtful design features. It is designed with straightforward fitting and ultimate reliability in mind. Everything needed for perfect fitment is included.

The kit also includes a replacement factory-spec oil/water cooler with a lower height, allowing for easy packaging of the assembly neatly in the space under the battery tray above it.

The oil lines feature an attractive outer nylon braid strengthened by a 210 Series stainless steel inner weave for maximum resilience. Protective external sheath avoids any rubbing damage in use. These feed and return lines run past the chassis leg into the bumper cavity, then connect to the oil cooler core.

The front-mount location brackets for the cooler unit itself places it in the optimum airflow and ensures that oil temperature drops and excess heat is funneled out efficiently.
