A BMW tech I know sent this to me, hope it helps.
Fault codes 2A67 valvetronic internal fault and
2A6B Valvetronic power limitation servomotor eccentric not moving to full lift. This is not something that you want to attemp to repair yourself there are special tools needed. Plus it will need to be diagnosed as to what has caused the failure such as: Electrical failure, mechanical failure, sensor failure, or internal engine component failure.
