GS7D36SG 7 Speed M-DCT
Fluid type DCTF-1
Important:
The M Double-Clutch Transmission (DCT) requires a special lubricant/hydraulic fluid: DCTF-1 Pentosin (P/N 83 22 2 147 477). This fluid is specific to the double-clutch transmission and should not be substituted with any other product.
Substituting the DCTF-1 Pentosin in M Double-Clutch Transmission (GS7D36SG) may cause significant damage to the internal clutches of the transmission assembly, requiring replacement of the complete gearbox, transmission oil cooler, and cooler lines.
The BMW DCTF-1 Pentosin fluid does not require regular service. It is an extended-life type of fluid and should not be replaced. Currently the fluid is in extremely short supply, and can be obtained only after a PuMA case is submitted to TeileClearing (Enhanced Technical Support).
