E88 14' Valvetronic dead?

Hello guys!

I was driving normally when I've noticed that down-shifting felt different, it had a slight delay and the rpms were kinda bouncing. At first I thought that the gearbox went out on me but after scanning with MHD I got these codes:

Active Codes
- 2DCE Valvetronic system: No adjustement possible.
Shadow Codes
- 2DD0 Valvetronic system: Warning threshold value, feedback control deviation exceeded.
- 2E11 Valvetronic system: bottom stop learned.

It drives fine, there's no limp mode or anything on the dash.
As it happened less than 30 minutes ago all I've done is Clear Codes and rewrite the MHD OTS Stage that I use but the codes come back 100%.

I'm over 800 KMs away from my goto mechanic, what should I do for now? Would it still be safe to drive as for now all the car does is downshift slowly? What parts should I get (Actuator, Shaft)?

Car:
- BMW 135i E88 w/ N55 engine (127k KM, maintenance done regularly, plugs/coils got 8k KM on them)
- Downpipe/Intake/Intercooler
- MHD Stage 2+
