Hello,

I have an issue with my M57.

The injector mass adjustments are surging from -3 to +3 on all cylinders. This results in shaky idle.
When revving up to over 1000rpm, it stops vibrating and the mass adjustments go back to near 0.

Other issues:
Blue smoke on cold start for some seconds
Blue smoke on harder acceleration
Slightly more difficult warm start

Checked:
Injectors bench tested and not faulty
No oil usage
Cooling system fine
No carbon buildup issues
MAF working
EGR, DPF disabled/removed.
No boost leaks
No issues or hesistation when driving/accelerating at any point

Video of the surging mass adjustments. In the end of the video, car is revved to 1200rpm:

Any ideas, what could be the issue?

I'd be getting the injectors tested. Any chance this vehicle had fuel contamination in the past?
