    Cars in limp mode with the fault but the garage I'm using can't find the problem.
    Anyone have any suggestions?
    The code is 00665
    Turbo has been off for inspection. It was clean and in good order
    Dpf cleaned out. Still going in limp mode

    Sorry to re post. Not sure what section was best to post this in

    Hope someone can help :(

    take it you have checked all your pipes for leaks? Is your "dv" okay? N75 valve and n249 valve okay?

    Are they using a generic fault code reader as using something like vcds will give a description of the fault too

    Nothing comes up on ross tech wiki

    this might be of some use

    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
    When found in 2.0l TFSI: Check Boost Pressure Control Valve (N249), for cracked rubber diaphragm. A new/optimized Valve is available under Part # 06H-145-710-D (or newer). RoW vehicles see: TPI 2016331 for details.
    NAR vehicles see: TSB 01-07-70 or 2013392 for details.
