Cylinder Deactivation System Oil Pressure Low

on 2007 Audi Q7 4.2L V8 · 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

  1. Check engine oil level and condition
  2. Measure oil pressure at deactivation gallery
  3. Verify correct oil viscosity
  4. Test VLOM assembly seal integrity
  5. 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.

The same data would cost $169/mo from Mitchell1 or $30/year from ALLDATAdiy — and you'd be renting access, not freeing it. Sponsor once, free forever.
