Did my engine blew up or something else?

My bike won't start today. Yesterday I rode it on the twisties for hours, no issues at all. I checked fuses, gs 911(no codes).
There was a Ducati/BMW techi around, he said battery/terminals are ok. It sounds like engine has no compression and it does not sound good. I tried to bump start it a couple of time, no bueno. I'm taking it to the dealership tomorrow. But what do you guys think?

I tried rain mode, etc... no beuno eithher. It just decided to die. @bennymx you must have seen this. Tell me my baby is not severely damaged. I only have 22k miles on it.

Fuel pump? I would think you would know if you blew up the motor.

Get that baby to your nearest BMW shop and let the tech check her out.

If its something major your covered for 3 years or 36,000?

Your video doesn't sound like a blown motor.

HAve you been riding in the rain? Do you have a belly pan? If so, you may have sucked water in via the hoses. This happened to a guy a the track, chased it for weeks until they figured out what was happening..

Well, just listening for such a short amount of turn over, it sure does not sound good. Like low on compression or off time. Are you really telling the whole story on exactly what it felt like and sounded like when you turned the key off last when this issue started?

All Keys Lost programming available
Cut keys and programming available
ECU to Cluster Matching available
Add / delete DDC available
All done here in the USA now.

I'll see what dealership techie finds out. Fuel pump would be an easy fix.

I did not ride in the rain, but this is interesting. How was the problem fixed?

What's the fix for low compression? New engine or something that can be fixed. It sounded normal last time I was riding it. A day later, same exact thing as in video.

Not fuel pump. Can hear it prime. Bit weird how it rode fine the other day and it doesn't now. A comp test will tell us if something has failed internally (valves, cams, rings). Almost sounds like no fuel or spark. But it could also be a crank sensor. If it is not supplying a reading to the ecu then she won't start. The sound is not good. I also don't like that there are no fault codes. Might have fuel and spark as I doubt you would have all coils or injectors faulty. If anything it would run on less than 4 cylinders. The fact that it doesn't start at all is saying it either has no fuel, no spark or no compression. Sounds like no comp.

I have seen these engines with high carbon build up on the valves and pistons causing low comp. If you didn't hear any noises from the engine when you last rode it. And it hasn't been progressively getting noisier over time then lets hope something hasn't actually failed. Might just need a clean up inside.

Things the dealer should do:
1. Check all live sensor status readings on diagnostic PC
2. Compression test
3. Leak down test
4. Check spark
5. Check fuel pump/ injectors
6. Remove rocker cover and check cam shafts, valve springs, retainers, timing
7. Remove cylinder head and inspect all valves for carbon deposit and condition of cylinder bores
8. Inspect all pistons for carbon deposits and inspect rings for wear or damage

Perhaps the cam chain jumped a tooth. That would explain no fault codes shown. New motor for z00!

Sounds expensive.

Please update when you find out what is going on.

You're also suffering from VVS.
