Abigail K. ★★★★★ Oct 22, 2026

Plugged this in and the ASD bypass worked exactly as described — no more fake engine noise through the speakers. The harness itself feels sturdy and clicked right into place without any fiddling. Cleanest audio upgrade I've made to the car so far.

Finally got rid of that annoying fake engine noise in my 2015 3-series—this harness was a perfect plug-and-play solution. The connectors clicked right in without any wire splicing or coding needed.

Finally, no more fake engine noise in my cabin. The harness was a perfect fit for my 2019 3-series and plugged straight into the factory connectors without any splicing.
