16683/P0299/000665 - Boost Pressure Regulation: Control Range Not Reached

Possible Symptoms

  • Reduced Power Output
  • Limp Mode

Possible Causes

  • Hoses/Pipes incorrect connected, disconnected or leaking
  • Charger Pressure Control defective
  • Turbocharger faulty
  • Diverter Valve faulty

Possible Solutions

  • Check Hoses/Pipes to/between Components
  • Check / Clean / Replace Charge Pressure Control
  • Check Turbocharger
  • Check Diverter Valve

Special Notes

  • If the Turbocharger is faulty due to mechanical / internal problems or the exhaust system is restricted (typically the Catalyst) this fault may be the end result.
Gasoline
  • When found in 2.0l TFSI:
    • Check Boost Pressure Control Valve (N249), for cracked rubber diaphragm. A new/optimized Valve is available, see parts catalog.
    • When stored in conjunction with misfire codes and/or fuel trim faults see the notes associated with the following faults regarding PCV failure: P2279, P1136, P1297, P1093 and/or P0507.
  • When found in All 2008 to 2015 Volkswagen vehicles with the 2.0L TSI Engines (codes CCTA and CBFA)
    • See Volkswagen Tech Tip 21-10-02.
      • https://static.nhtsa.gov/odi/tsbs/2015/MC-10122981-9999.pdf NHTSA
      • This Tech Tip suggests to check if the wastegate valve and lever has dropped and become stuck/seized causing either an over-boost or under-boost fault. P0299, P0234 or P0236.
      • This concern can be intermittent also clearance between the turbocharger housing and the wastegate lever should be about 3.0mm.
Diesel
  • 2009-2014 VW NAR with 2.0 CR-TDI (CBEA/CJAA), TSB 21-14-03 or TPI 2026771 has several items to inspect and verify to factory design.
  • When found in VW Golf/Jetta (1K): 2.0l CR-TDI (CBEA/CJAA).
    • Verify the mechanical part of the Exhaust Valve Control Module (J883) is not seized or binding.
  • When found in the 1.9 L TDI-PD (BLS):
    • Check vacuum supply from the vacuum reservoir located in the valve cover for leaks. Using a vacuum gauge, wiggle the valve cover and hose connections to check for a leak. The following photo was submitted from a customer working on a 2010 VW Caddy (2K chassis) with this vacuum reservoir problem.
