1209152018-11-13. Service bulletin. VEHICLE SPEED CONTROL; VEHICLE SPEED CONTROL:ACCELERATOR PEDAL. "SUBJECT N55: Slight Surging at Constant Speeds when Accelerating Very Lightly. The vehicle shudders or surges slightly while driving at constant speeds and applying the accelerator very lightly. This symptom is most easily reproduced under light loads when the current fuel consumption is approximately 3448 miles per gallon. The current fuel consumption can selected and monitored in the instrument cluster while driving (the ""fuel consumption, current"" option is set to active in the settings menu). No relevant fault will be stored in the DME memory. DME software; the fuel injection rate under these conditions is too close to the minimum calculated threshold."

Replacement of the crankshaft 4. Replacement of the crankcase (block) with pistons 5. Replacement of the engine assembly Due to slight tolerance differences with the new replacement hardware and the original learned crankshaft position, values could cause cylinder balance calculation errors by the DME.
