M57 cranks but won't start (video)
Hello everyone,
I have a 07 330xd 231hp MT which is giving me trouble. Engine cranks, but won't start. Last week I was driving on the highway at around 100km/h in 6th gear. I switched to 4th gear, tried to rev and it just made kind of "missfires", so I pulled over until I was almost stopped that the car stalled with clutch pressed. After that, it was impossible to start the car, it just cranks, but won't ever start. I changed injectors 3, 4, 5 because the car had 4-6s long cranks before. I thought that might be the solution... but that changed nothing. I primed/bleed the fuel system. Nothing. I can hear the low pressure fuel pump (LPFP) working. No fault codes on INPA. Here's a video: [u2b][/u2b] I am also thinking... timing chain broken / snapped?

It's not a broken timing chain, but maybe it's skipped a tooth or 2. I think that would make sense, to have no codes too.
Nothing else I can think of makes sense for the symptoms; sudden failure, no codes, uneven cranking, no start but seems to still fire on maybe one cylinder (just). I'd check the chains/timing ASAP. |

Thanks for your replies!
There is an update: since I wasn't able to diagnose further myself, I took it to a workshop. They testested the injectors, all were ok. They found no compression on cylinders 5 and 6. That means engine broken... I can't explain the cause, and I don't know what's exactly broken... Sadly, I won't repair it, since it's not worth it anymore (too much to spend on a new engine).
