Hi Guys



I hear weird sound from the engine.
Is it normal sound ? Can it be a timing chain ?? or maybe something different ?
When engine is hot, it is not that loud.

My car:
F30 320d Sport 2012r
Mileage: 82000mile
Automatic

That's the sound of your injectors.. it is normal with the n20 engine...

The OP has a 320d, which has an n47 engine. The sound is normal.

It was timing chain. I prepared for you video with noise that broken timing chain was making(swish swish sound on background) and how it sounds after the repair. could be useful for one of you.
Don't panic, the newer the car the lower the risk. Probably many cars are not affected but It is worth to listen the engine. In my case mechanic said that it was an early stage and probably it won't fail soon, but it could caused an impact of gearwheel on crankshaft which is unreplecable. All is good now !

It must not have completely broken - ie, the links fallen apart. More likely the tensioner or guide broke? (Broken timing chains crater the engine as valves and pistons crash into each other.)

Thanks for the new vid/audio. Hard to get good recordings of these things; have to be there...
