Trifecta seems to usually come down to bad wheel speed sensor, steering angle sensor, or DSC (ABS) module. My personal experience ended up as the last one. I’d get the trifecta after 10 or so minutes of driving, which as it turns out is about how long it takes the DSC module to warm up and short out.

Don’t have a code cheat sheet with me to decipher yours, but I was popping DSC and transmission codes telling me that these modules stopped communicating. And all the wheel speed sensors were looking good on the foxwell.

There are tons of really good trifecta posts here, and on bimmerforums that can help you troubleshoot. If and how the cluster has failed can give some good clues as well if I recall. Hopefully it’s not the DSC module, but if it is you can get a working used piece. I tried used and couldn’t get it to work, so had to buy a new one, which sucked.
