Applies to: S55 twin-turbocharged inline-6 / 3.0 - not every engine this model has been sold with

Symptoms to watch for

  • Drivetrain malfunction warning light with the vehicle entering a protective 'limp' mode
  • Rough idle and stuttering once timing has deviated
  • In advanced cases: real risk of piston-to-valve contact and severe internal damage

What To Check

Not reliably detectable unless the vehicle is actively presenting the drivetrain malfunction light/limp mode symptom - an internal timing-reference fault with no other early external sign.

This is everything documented for this issue - no repair-cost estimate or TSB/recall reference was found for it, so there's nothing further behind a full report for this specific finding.

Estimated Service Costs

Major serviceR 18,000
Annual upkeepR 22,000
Brake job (pads/discs)R 9,000
Filter kitR 2,200
