DSG Oil Cooler / MQB / MQB EVO / DQ381 7 Speed

It’s not just your engine oil that you need to protect. Your DSG gearbox is susceptible to overheating. And the higher your power, the harder you drive, the more important it is to protect it.

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.

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 15 – 20 degrees centigrade (of course dependant on how the car is being used, ambient temps and state of tune).

The kit uses a clever design which retains the 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.

Only when the oil exceeds normal temperatures, the thermostat opens. Oil temperature then drops 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.

What’s included in the kit

Oil cooler mounting brackets

AN10 210 series Nylon braided feed and return line

Billet CNC thermostatic adaptor block

Replacement, low-profile oil/water cooler

AN10 10-row oil/air cooler core

Fitting kit containing all necessary nuts, bolts, washers and rubber mounting bobbins

The kit for all MQB cars comes supplied with two bracket kits. One kit is for Audi S3 models, the other is for all Golf 7 and other MQB models. Mounting for the bracket set requires drilling bolt holes through the front crash bar.
