Cylinder Deactivation System Oil Pressure Low
on 2017 Audi R8 5.2L V10 (Gen 2, 562hp) · AWD
What this code means
The oil pressure dedicated to the cylinder deactivation system is below the minimum threshold for reliable lifter switching.
Symptoms
- Check Engine Light
- Cylinder deactivation disabled
- Engine noise during attempted deactivation
- Lifter tick on deactivation command
- Oil pressure warning at idle
Common causes
- Low engine oil level
- Oil pump wear reducing pressure
- Wrong oil viscosity installed
- VLOM assembly internal leak
- Clogged oil filter restricting flow
Diagnostic steps
- Check engine oil level and condition
- Measure oil pressure at deactivation gallery
- Verify correct oil viscosity
- Test VLOM assembly seal integrity
- Inspect oil filter for restriction
Repair notes
Top off or change engine oil with correct AFM-compatible specification. Replace oil pump if pressure is low at all speeds. Replace VLOM if internal leak found.
