Product description:

Why does oil come out of the DSG vent at all when using Launch Control or in vehicles with enhanced performance?

  • During normal driving, the pressure in the transmission is moderate → there is hardly any oil mist coming from the vent.
  • However, as soon as you use Launch Control or drive a TCU tune with higher clutch pressure (e.g., HPerformance Stage 1 with transmission software), the hydraulic pressure in the mechatronic system increases dramatically (often >20 bar).
  • This pressure forces a fine mist of ATF oil out through the mechatronics vent hole (the small black tube at the top of the transmission).
  • The mist then settles in the engine compartment → oily grime everywhere, especially on the intercooler, intake, underbody, etc.
  • In extreme cases, liquid oil can even leak out and drip down (a common occurrence in many 400–600 hp Golf R / S3 / TTRS models with aggressive launch control).

What exactly does the milled HP DSG catch tank do?

  • It is connected directly to the original vent on the mechatronics unit.
  • The oil mist condenses in the tank → the oil collects at the bottom.
  • Our catch tank has a return line → the separated oil flows back into the transmission in a controlled manner (no oil loss!).
  • Result: The engine compartment stays clean, there are no oil leaks, and the transmission retains its full oil capacity.
The engine can still be washed, as the design prevents water from entering.

Scope of delivery:
  • Machined aluminum catch tank (color of your choice)
