This is Part 1 of Ben Martins' latest case study which follows the intriguing journey to diagnose the reported issues: a large number of warnings on the dashboard accompanied by a warning message on the instrument panel, along with the vehicle entering limp-home mode before coming to a complete stop.
"In this ever-changing world, there is one constant in our trade: cars will break down. As we try to build our knowledge and the level of complexity increases, there are always things that can trip you up. This particular case was no exception, with twists and turns all the way!
We were asked to take a look at a 2014 Mercedes E300 BlueTec Hybrid. The reported issue was a large number of warnings on the dashboard accompanied by a warning message appearing on the instrument panel. The vehicle would then enter limp home mode before coming to a complete stop. Only switching off the vehicle and then restarting it returned the ability to drive the car."
