16396/P0012/000018 - Bank 1: Camshaft A (Intake): Advance Setpoint not Reached (Over-Retarded)

Possible Symptoms

  • Erratic Idle

Possible Causes

  • Intake Camshaft Adjuster tight/stuck
  • Intake Camshaft Adjuster faulty

Possible Solutions

  • Check Intake Camshaft Adjuster
    • When the Intake Camshaft Adjuster uses oil pressure to control the adjuster, check the oil pressure. The 1.8T is notorious for issues but any engine with low oil pressure or restrictions in the system could result in various timing DTC's such as 17748/P1340/004928.
    • Use Output Test, Meas. Value Blocks (MVB) & Basic Setting
