Don't be alarmed when you find that the new timing chain also is loose. It depends on exactly where the motor stopped at that particular start. I have checked mine many times; sometimes it feels loose, sometimes it does not.
If they also are replacing the TC tensioner, I would pay attention to which part number they put in. BMW has used at least three different TC tensioners in the N20 motor. Surely there is a reason for that, so I went ahead and changed the tensioner myself. I posted a DIY on the F26 subforum.

Knowledge is power.

PS: Congrats on your "steal."
