We’ve got another quick one, this time related to a Mercedes-Benz E550, but with implications across the model offering. In this post, Will from Rhode Island breaks down issues he encountered on his own vehicle, which occurred while he was performing an entire suspension update.
As he notes, “Just prior to beginning the work, I had the classic “ghost codes” (alternator serial interface, icy throttle body, etc.) failure on my ME9.7 ECM.” This made us think of our classic questions, Is it hardware, software or signal? He also went through the same questions, leading him to start by attacking the software via updates. When that didn’t resolve the issues, he moved on to other possible culprits until he found the root cause. Check out the full post for complete details.
