P1030: Manufacturer-Specific Powertrain Fault (BMW Valvetronic Sluggish Movement)
6 vehicles · 1 makes · $150-$4,000 repair
Most Reported On
P1030 is an OBD-II diagnostic trouble code meaning “Manufacturer-Specific Powertrain Fault (BMW Valvetronic Sluggish Movement).” P1030 is a manufacturer-specific powertrain code that, on BMW/MINI engines, is generally associated with the Valvetronic eccentric shaft moving too slowly or sluggishly compared to the commanded rate of change. It typically points to a weak actuator motor or mechanical binding rather than a pure sensor fault, indicating the variable valve-lift system cannot respond quickly enough. Because the definition can differ between automakers, the exact fault should be verified with manufacturer service information. This code is most commonly reported on 2008-2013 BMW M3, 2017-2024 BMW M240i, and 2009-2015 BMW 7 Series (750Li, 750i, 750iL), plus 3 other vehicles, with repair costs ranging from $150 to $4,000.

FAQ
What does P1030 mean?
P1030 stands for "Manufacturer-Specific Powertrain Fault (BMW Valvetronic Sluggish Movement)." P1030 is a manufacturer-specific powertrain code that, on BMW/MINI engines, is generally associated with the Valvetronic eccentric shaft moving too slowly or sluggishly compared to the commanded rate of change. It typically points to a weak actuator motor or mechanical binding rather than a pure sensor fault, indicating the variable valve-lift system cannot respond quickly enough. Because the definition can differ between automakers, the exact fault should be verified with manufacturer service information.
What are the most common causes of P1030?
The most common causes of P1030 are: Weak or worn Valvetronic actuator motor, Mechanical binding/wear in the eccentric shaft, Oil sludge or contamination slowing shaft movement, Faulty eccentric shaft position sensor, Wiring/connector resistance in the motor circuit, Low or degraded engine oil affecting operation. The specific cause varies by vehicle.
