ME 1 Downloadable Content # 1, Bring Down the Sky, was hard to find (it's no longer searchable on the EA store or Origin.com, although the 2nd DLC (Pinnacle Station) is still available on Origin for $5. I finally found official instructions on how to download and install the first DLC: https://help.ea.com/article/mass-effect-bring-down-the-sky-dlc-redemption

If you receive a “You have reached the activation limit.” message, you will need to use the Talk to a Game Advisor (https://help.ea.com/connect-with-us) feature on our site and we will be able to unlock it for you. We apologize for the inconvenience this may cause.

This works with Steam versions of Mass Effect (1) as well as disc based versions. You will definitely need to contact Origin for a CD key, but it's no hassle: https://help.ea.com/connect-with-us. You don't have to provide an original CD key for Mass Effect or anything - just tell them that the provided key for BDtS is oversubscribed. I used the e-mail option because I contacted them after business hours, and I got an e-mail response with the new key early the next day!
