Is it possible to replace belt tensioner DIY.

I was working on my BMW 545i - 2004 to remove my alternator but in the process I pulled the belt tensioner too much and the torx hole was broken. Could anyone tell me whether I should replace a new blet tensioner or not. If I can also get the part number will be of great help. Thank you.
