Naz, you can mark the thread title as fixed and I am bumping it to help out others.

Long story short, use DIS scan tool. In the last 2 years the intermittent trifecta which would come on, and reset at the next drive cycle was cumbersome but didn't really effect me. About a month ago I wanted it gone for good.

I sent my ABS module for a rebuild (prevenatively and I thought it might be my issue) and after receiving back I had received 2 random trifectas since then. So I hooked up DIS. THE ONLY CODE I HAD ON MY ABS MODULE was 2 codes for Brake Light Switch.

Bought a new one from the dealer, installed on Saturday morning 2 weeks ago and installed. Has not been back since.

In my case the trifecta was a Brake Light Switch ($33) from BMW needing replaced.
