Persistent issue even after retiming the engine
So update, I just retimed the engine, althought it was already in time, the same issue arises. Almost sounds like something is slapping at an slow rate in the engine (sounds like the vanos spring? Unsure). I even disconnected the vanos solenoids, no change. I will buy ista p to try and diagnose the issue further, but so far still very clueless, any help would be very much appreciated.
