Half check engine+Valvetronic motor issue+Lack of power

[Sandbravo]

Hei guys, Im new here Bimmers also new in Norway. Have a 320ia e90 2005. The problem comes with every cold start, pops up half check engine light (Power Reduced), Fault codes: 2A69 Valvetronic Voltage Supply Servomotor 1, 2A6B Valvetronic Power Limitation Servomotor. The car runs on Limp Mode. When the engine is hot, I erase the fault with Carly or torque, the car leaves the Limp Mode but I feel a distinct lack of power.
I've taken the engine noise protection to see if I can do it by my self but do not dare. I do not see how to takes it out. As extra information, I have seen the connection of eccentric shaft sensor is soaked in oil, but does not leave any fault code related to this sensor.
Should I go ahead and replace the VVT motor or it could be something else?
I'm really desperate, if any expert on BMw's or someone who has been the same, please contact me.
Regards.

Its a common problem on those engines, so take the chance and change it:-)

Thanks dude! Do you think it is not related to Eccentric Shaft Position Sensor?
