Problem: 2011 smart 451 suddenly losing power and going into limp mode with muted power output.

Solution: Refueling from one bar of fuel restored normal power; possible fuel contamination or sensor issue related to low fuel level.

Key facts: - Vehicle was normally functioning until the morning of the issue - Symptom: muted power and inability to rev out - Fuel level was at one bar when problem occurred - Problem resolved after refueling to full tank - Experienced forum member (jwight) suggests fuel level alone is unlikely cause and recommends OBD-2 code scan for drivetrain/wheel speed sensor codes - Thread cut off mid-reply so final diagnosis unconfirmed
