Hi, I have a 2007 S550. Frequently, when I am driving, the engine speed becomes restricted limiting the speed of the car. If I switch to neutral and back again to drive, the car will run normally until the next time the problem arises. It also arises when the car is in cruise control. No faults appear either on the dash or MB diagnostics (DAS). Thanks
I see a similar question: "2007 Mercedes S550: Intermittently..type of limp mode..cruising..rev" FYI. Thanks
I just pulled up WIS, so I know how to check the wiring back to the ECU. Plus I'll recheck the connections. I'll do this tomorrow and advise. Thanks
I checked all connections on the pedal sensor and the throttle. I checked over the looms. I can't see anything wrong. The butterfly moves freely on its spring as does the gas pedal. Everything is clean.
The issue remains, unchanged. Next steps? Best,
Hi Matt, we are setting up to update the software on the modules. Will do so and link back in a day on so, best,
