R8 · Dual clutch · Seven ratios
0BZ S TRONIC TELEMETRY
The seven-speed chapter that retired R tronic for many R8 drivers — dual wet clutches, launch logic, and supercar shift energy. A different visual language from DSG.LAB: acid trace on carbon, not laboratory cyan.

What the code means on the floor
In VAG workshop vocabulary, 0BZ identifies a specific 7-speed dual-clutch transaxle family used behind mid-rear V8 and V10 R8 applications (see SSP 643 for factory framing). Think longitudinal, high-inertia launches, and cooling circuits sized for track-adjacent use.
Channel B · Timeline
From R tronic to seamless power
- Pre-0BZ — R tronic automated manual: characterful but slower shifts than modern DCT expectations.
- MY2013 refresh — 0BZ S tronic broadly replaces R tronic on the first R8 generation for many markets.
- Type 4S — second-generation R8 continues dual-clutch philosophy; always verify transmission tag and PR codes.
Channel C · Hardware
Packaging & behaviour
Two clutches alternate odd/even shaft families for overlap shifts — the supercar brief is minimal traction interruption. Mechatronics, temperature models, and clutch touch-points differ from MQB DQ units; spare strategy is specialist by design.
Channel D · Service
Fluids, adaptation, documentation
Fluid grade, fill procedure, and basic settings belong to official repair manuals. Enthusiasts should log clutch touch-points, temperature trends, and fault frequency before swapping mechatronics units.

Decoded questions
-
Is 0BZ the same as “DSG”?
Same dual-clutch physics, different hardware family. Audi markets it as S tronic on R8; workshop codes matter more than the sticker.
-
Can I use generic VAG fluid?
No guessing. Match the exact lubricant class in the transmission identification and market-specific bulletin — supercar gearboxes punish wrong viscosity.
-
Why the green-on-black theme?
0BZ.TRACE reads like a telemetry overlay — a deliberate contrast to copper editorial (V12 TDI) and cyan DSG.LAB.
