    The last few thousand miles I have been having shifting problems with my DSG. Difficulty shifting as speed/acceleration increases. I queried the car using VCDS and found the above fault--the DSG was not showing any fault codes. Although the fluid and filter were changed about 25k miles ago, I drained and put new fluid and filter in. I cleared the faults and went through DSG calibration procedure. After driving it for about 250 miles, the shifting seemed to improve and almost return to normal. Today, the engine light came on and noticed some shifting problems again--staying in low gears and really dragging going up hills. I queried and found the same fault. I cleared it again but not driven car since. I expect it will come back once I start driving through full range again. Could I have an issue with my catalytic converter? Manual states exhaust issue with this trouble light. I did a quick check under the hood and didn't see any hoses disconnected or broken, but will be doing a more detailed investigation. The car has 173K on it and no exhaust parts have ever been replaced or serviced. To date, the DSG has worked flawlessly and never needed any adjustments. Does anyone have any ideas or suggestions? Thanks for any help as I am very perplexed.

    You don't show an error code I'm assuming its:

    VAG Error Code: 16619/9779/000565

    EOBD II Error Code: P0235

    Fault Location:
    Boost Pressure - Regulation Range not Reached

    Possible Cause:
    Malfunction Indicator Lamp (MIL)(K83) active.
    Reduced power output.
    Limp mode.
    Limp mode: What is it, what are the causes, and how to fix it for the Audi and VW TDI diesel turbo

    Hoses/Pipes incorrectly connected, disconnected, blocked or leaking.
    Charger Pressure Control defective.
    Solenoid Valve for Boost Pressure Control (N75) defective.
    Turbocharger defective.

    Possible Solutions:
    Check Hoses/Pipes to/between Components.
    Read Measuring Value Blocks (MVB).
    Check Charge Pressure Control.
    Check Solenoid Valve for Boost Pressure Control (N75).
    Check Turbocharger.

    Was that the only error code VCDS showed?

    I took a short drive this morning and after stressing and heating up the engine, the fault re-appeared and really dragging up the hills again even though acc pedal is to the floor. Here is the only fault reported by VCDS:

    000665 – Boost Pressure Regulation

    P0288 – 000 – Control Range Not Reached

    Freeze Frame:

    Fault Status: 01110000

    Fault Priority: 0

    Fault Frequency: 1

    Reset Counter: 255

    Mieage: 279855 km

    Time indication: 0

    Date: 2000.00.00

    Time: 21:23:08



    Freeze Frame:

    RPM: 2079 /min

    Speed: 96.0 Km/h

    Load: 47.8%

    Are you 100% sure your using a genuine VCDS cable and not a cheap Chinese cloned cable?

    VAG Error Code: 16672


    EOBD II Error Code: P0288

    Fault Location:
    Injector 10 - Circuit Low/Short Circuit to Earth

    Possible Cause:
    Malfunction Indicator Lamp (MIL)(K83) active.
    Engine Misfire.
    Engine Run Rough.
    Low MPG.

    Fuse(s).
    Wiring/Connector(s) short to earth.
    Injector 10.
    Engine Control Module (ECM).

    Possible Solutions:
    Check/Replace Fuse(s).
    Check/Replace all faulty Wiring/Connector(s).
    Read Measuring Value Blocks (MVB).
    Signal current < 2.1 A.

    Tech Notes:
    Clogged or partially clogged fuel injector can cause this code. Start by performing an injector flush before replacing the injector.

    Description:
    Code P0288 is triggered when the Engine Control Module (ECM) detects a low voltage in the Fuel Injector 10 Circuit. During normal conditions the Engine Control Module (ECM) turns the Fuel Injectors ON and OFF in the Fuel Injection System.

    Keith,

    Yes I am absolutely sure. I purchased the cable new from Ross Tech shortly after I bought the new car. I never use a cheap Chinese anything if I can help it.

    This is interesting but maybe understandable given mileage and hard use of the car over the years. I will check the injectors. Thank you for the advice.

    That's ok I thought I should ask first.

    You can make sure your VCDS cable is registered then you can join Ross-Tech forum and make a new thread about your problem with a full AutoScan posted.

    VAG Error Code: 16683/000665/11226/15343/5671/7384

    EOBD II Error Code: P0299

    Fault Location:
    Boost Pressure Regulation - Control Range Not Reached/Low Boost

    Possible Cause:
    Malfunction Indicator Lamp (MIL)(K83) active.
    Reduced Power Output.
    Limp Mode.
    Limp mode: What is it, what are the causes, and how to fix it for the Audi and VW TDI diesel turbo.

    Hoses/Pipes incorrectly 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) (Turbocharger Recirculating Valve) for cracked rubber diaphragm. A new/optimized Valve is available under Part # 06H-145-710-D (or newer).
    Rest of World (RoW) vehicles see: Technical Product Information (TPI) 2016331 for details.
    North American Region (NAR) vehicles see: Technical Service Bulletin (TSB) 01-07-70 or 2013392 for details.
    When stored in conjunction with misfire codes and/or fuel trim faults see the notes associated with the following faults regarding Positive Crankcase Ventilation (PCV) failure: Crankcase Breather Valve
    When found in Audi A4/S4/RS4/Cabriolet (8K): 2.0l (CAEB):
    See Technical Product Information (TPI) 2031245/6 - turbocharger excessive waste-gate play.

    Diesel:
    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.

    Ok Keith, I have tried a few things. I purged the injectors 3 times using Diesel purge and got the solution nearly clear. But no change in the problem. I noticed the Turbo actuator shaft does not move at all either when starting or pushing the accelerator pedal. Since I have no power off the line and at all the low RPMs thinking it might be stuck open. I disconnected vacuum line coming from N75. I can feel the vacuum in the N75 line so thinking that might be ok. I attached vacuum pump to actuator and does not appear to hold vacuum. I have not checked the catalytic converter as I don't know how other than to disconnect exhaust pipe and drop for inspection.

    Turbo actuator bad. Replaced turbo. Everything fine now.
