E90 n52 rattle + 2A95, 2A99, 2A98 codes

Hello family, hopefully you guys can help me diagnose my current issue with my 2006 330xi.

While driving to work today, I noticed a faint surge in power, as well as a slight rattle sound coming from the top of the engine. Upon scanning the car with the Protool app, I pulled up these codes: (2A95 crankshaft sensor, synchronisation) + (2A99 crank shaft - outlet camshaft, correlation) + (2A98 crank shaft - inlet camshaft, correlation)

Any help is appreciated!

Timing chain jumped a tooth or two?
I would check timing first.

Also might be Vanos gears.
