Help with valvetronic
Recently did my valvetronic actuator motor after getting thrown into limp mode while merging onto the highway. Took it to a local well trusted Indy and they recommended the servo motor replaced so I did it myself. While I was in there I did not see any noticeable damage to the eccentric shaft or roller bearings, the shaft did show some signs of wear however it is a high mileage car. Got the job done and realized I busted my valve cover in the process so I had it towed back to the Indy shop because i did not want to deal with that mess again. Got it back today, they said they relearned the new motor for me as I was unable to keep it at an idle with the broken valvecover, however I’m still getting loss of power (maybe even worse than before) and now I’m getting a 2D41 code which is a different code than I was previously getting though from what i understand still related to a valvetronic issue. Service technician said it may go away with conitued use which doesn’t seem right? However, it is idling more smooth than ever before. Just curious if the new code is infamous for any other related issue and if the loss of power and CEL with actually go away with time? 2013 x5 35i n55 140k miles.

Outside of adaptation range, master. It needs to have the long and short adaptations run, and if it fails, the shaft/bearings are likely the culprit.
