Service bulletin B121916
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
"N63R - VALVETRONIC ACTUATOR POSITION FAULTS CAUSED BY POOR HARNESS CONNECTION. The Service Engine Soon (MIL) Lamp is on and a ""Drivetrain Malfunction"" Check Control warning may be displayed. A connector on the engine wiring harness is not correctly locked or there is a problem with the pin contacts resulting in sporadic connection error. Any of the following Valvetronic faults may be stored: 136608 - Valvetronic servomotor 2, position sensors, signal: Not plausible 136408 - Valvetronic servomotor 2, position sensors, signal: Short circuit or open circuit 135808 - Valvetronic servomotor 1, position sensors, signal: Not plausible 135A08 - Valvetronic servomotor 1, position sensors, signal: Short circuit or open circuit These additional faults for bank 2 may also be stored: 135B10 Valvetronic servomotor 2, triggering phase U: Line break 135B11 Valvetronic servomotor 2, triggering Phase V: line break 135B12 Valvetronic servomotor 2, triggering Phase W: line break Any of the following consequential faults would be set as a result of the Valvetronic problem: 102902 air mass 2, plausibility: air mass too low 120408 boost pressure control: shutdown due to reaction 120908 boost control 2: shutdown due to reaction 107001 throttle angle 2 - absolute pressure suction pipe 2, comparison: pressure too high Additional misfire faults are also possible: 140001 - Misfires, several cylinders: injection is switched off 140501 - Misfire, cylinder 5: injection is switched off 140601 - Misfire, cylinder 6: injection is switched off 140701 - Misfire, cylinder 7: injection is switched off 140801 - Misfire, cylinder 8: injection is switched off"
