Woodruff Key (DIN 6888 3x3mm?) for Crankshaft-BMW C400X 2019

[DoureiosIppos]

Hi everyone,
Need help sourcing a woodruff key for the crankshaft on my BMW C400X K09 engine (2019 model). From what I’ve found, it’s typically a DIN 6888 type, around 3x3mm or similar size.

My mechanic says it’s tough to find as a standalone part—BMW apparently only sells it bundled with the full crankshaft assembly. Bike has ~27k km,. Located in Greece (EU shipping preferred).
• Confirmed OEM part number or exact specs?
• Any reliable sources (dealers, online like RealOEM/eBay, aftermarket suppliers)?
• Installation tips or if anyone’s replaced just the key successfully?
Appreciate any leads!

for example https://www.mcmaster.com/products/din-6888-machine-keys/

25 keys for maybe $20.

This is in the US where metric is just a bit less common than in Europe, should be easy to find where you are.

No help for you from me, I'm sorry to say.

But I wonder whether you've seen this 20-minute video. It shows what's involved in the C 400 engine:
