BDT How To Diagnose and Install a DSG Mechatronic Unit Replacement - Audi B8/B8.5 S4 3.0t

How's it going BDT Squad?

We are finally posting the dreaded mechatronic unit replacement video! This is probably one of the most common failures on the B8 S4, and there is zero information on it. So, since our mech unit was acting up, we thought it'd be helpful to document the process. We start the video with a quick diagnosis, and then we jump right into the install. Now, this is not the simplest of tasks and we had more than our fair share of headaches during this install, but everything worked itself out thankfully!

We hope this will help you if/when this happens to you!

As always feel free to leave any questions down below, and until next time, Stay TUNED!
