Starter Motor Help — NBW Gearbox + CBZB 1.2 TSI + 13-Tooth Flywheel

Hi all,

I’m in need of some proper advice from anyone who’s dealt with cross-compatibility between gearboxes, flywheels, and starter motors.

Here’s my setup:
  • Engine: 1.2 TSI CBZB
  • Gearbox: NBW (5-speed manual)
  • Flywheel: 03G 105 271 D (solid, 110-tooth)
  • Starter required: 13-tooth, but must bolt to NBW gearbox
The Issue:

I’ve tried a few starters already (including 0AH 911 023 F and 02T 911 023 K/M/N) — but they either:
  • Don’t physically bolt to the NBW bellhousing
  • Or they have 10 teeth and don’t engage with my 110-tooth flywheel properly

The original clutch and flywheel were from the LNY gearbox setup, and the flywheel was reused. Everything fits and runs great — I just can’t find a matching 13-tooth starter that bolts to the NBW.

What I’m asking:

  • Has anyone got a confirmed 13T starter that bolts onto the NBW gearbox?

Really stuck here, and appreciate any help you can offer.

Cheers,

Jack
