Racingline 7 Speed DQ381 DSG Cooler - Audi 8V S3, 8S TT, TTS, VW Mk7.5 GTI, GLI, Golf R
WHY FIT A DSG OIL COOLER KIT?
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.
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.
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.
DSG COOLER FITMENT.
As you’d expect, the RacingLine DSG Oil Cooler is a beautifully detailed complete kit, developed exclusively for the DQ381 7-speed DSG gearbox.
The system is designed for straightforward fitting and ultimate reliability. Everything needed for perfect fitment is included.
- Unlike other DSG oil cooler kits, the RacingLine package keeps the oil/water cooler and adds to it with the oil/air cooler
- 10 row stacked-plate oil cooler radiator, flowed to obtain maximum heat dissipation without undue pressure drop
- Optimum front mounted location behind left side front lower grill aperture with all necessary brackets and fixing kit supplied
- 210 Series stainless steel, nylon braided feed and return lines run past the chassis leg into the bumper cavity, then connecting to the oil cooler core
DOUBLE COOLING.
Racingline's DSG Cooler design is a unique design: it retains the factory oil/water cooling system, plus adds our oil/air cooling as well. Why?
- The DSG oil will still quickly warm up 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.
- That's the point at which our sophisticated thermostatic control valve inside the adaptor block will then divert hot oil out to the new 10-row cooler located in the cool fresh air flow whenever temperatures rise.
- After the cooled transmission oil returns from the cooler, it carries less heat to be absorbed into the engine coolant system - helping control all the temperatures under the bonnet.
- Racingline's replacement oil/water cooler (that's the silver part) is lower in height than the factory one. So the total height of both parts fits perfectly under the battery location above it.
SO WHAT'S 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

BRACKET SETS
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.
