Good morning all; first post here as I have been reading and did a lot of lurking here prior to purchasing my car. Last week I picked up a 2015 428XI that I am super excited to have.

I have ordered and am planning to replace my timing chain tensioner. I know there is some debate on if that is something to do as "maintenance" or not, but in my mind they updated the part; so something is obviously different. So I plan to change it.

My question is; I have read at lease one post where when the old tensioner was removed, the engine timing changed (can't recall if this was here or another forum) but it had me wanting to confirm. The actual BMW tech manual says nothing about needing to remove valve cover lock cams ETC, when replacing a tensioner but wanted some real world feed back on if there is a risk.

Plain and simple; can anyone confirm for me that the timing and everything will stay in position if the only thing I do is remove the tension and replace it with a new one?

Thanks so much.
