BMAX Engine Smoke and Power Loss

Hey, that sounds familiar. I have a BMAX too (not sure about the year), and I had similar symptoms last year - check engine light, loss of power, and some smoke. Did you check for any obvious leaks?

Thanks for the reply! No, I haven't spotted any visible leaks. But where exactly should I be looking around the ventilation system? Is it something I can easily check myself or is it better to just take it to a mechanic?

Honestly, based on my experience and similar symptoms, and the fact that you're seeing smoke, it's likely a defective crankcase ventilation. I ended up taking mine to a workshop. Saved me a lot of hassle.

Thanks, I appreciate the advice! I'll take it to a trusted mechanic. Seems like a job better left to the professionals, especially with the smoke issue. I will post what the issue and costs are once I have it resolved. It was indeed the crankcase ventilation valve. Cost me about 360€ to get it fixed.
