    Gt sport tsi 170 mk5 golf misfire

    Hi all

    I am new to the site but require a little help.

    My car has a misfire on cylinder 1 when I plug in vcds.

    The misfire seems worse when at high idle.

    It has lumpy idle and stutters a bit. If you put your foot to the floor it seems to pull ok.

    Vw could not find a fault. No fault codes. I have new plugs. Swapped coil packs over. Cleaned map sensor. Still misfires and stutters.

    Any help greatly appreciated.

    Cheers

    Tim.

    Get a compression test done, I have had to do the heads on these due to a burnt exhaust valve and I have another in tomorrow with the same problem, getting very common.

    Welcome to the forum Tim.

    If you have VCDS then do an AutoScan and post the error codes.

    Post moved to the proper section.

    If you want to add your details in VAG-COM/VCDS User Locations that would be great?

    Can I suggest that you add your car spec to your signature as it will save users asking every time, if you know the engine code that will also be great? Oh you can't do this of a phone. Adding your car spec.

    I don't have any error codes. It doesn't seem to misfire enough to throw a code. Although when I put vcds on on a cold start it misfires loads of times.

    Compression test all fine. Any other ideas? Car was running smooth the other day although still lumpy on tickover.

    Boost gauge goes to max briefly sometimes when pulling away I've noticed. Is that normal or part of the fault do you reckon?

    My eml light flashed for about 15 seconds the other day. I now have 3 fault codes.

    Anyone recommend anything?

    VAG Error Code: 16490
    EOBD II Error Code: P0106

    Fault Location:
    Manifold Absolute Pressure (MAP) Sensor (G71)/Barometric Pressure (BARO) Sensor (F96) - Range/Performance Problem

    Possible Cause:
    Malfunction Indicator Lamp (MIL)(K83) active.
    Engine rough idle.
    Engine hesitation.

    Intake/Exhaust leak.
    Wiring.
    Manifold Absolute Pressure (MAP) Sensor (G71).
    Barometric pressure (BARO) sensor (F96).

    Possible Solutions:
    Check Engine Control Module (ECM) Software Version.
    See Special Notes for Details.
    Check Timing.
    See Special Notes for Details.
    Check Wiring and/or Connections from/to Manifold/Barometric Pressure Sensor (G71)/(F96).
    Check for Leak in Air Intake and/or Exhaust.
    Check/Replace Manifold/Barometric Pressure Sensor (G71)/(F96).
    Check/Replace Engine Controle Module.

    Special Notes:
    On certain smaller Engines we've seen cases where a buggy Engine Control Unit Firmware can cause these fault codes, additionally there are known Problems with the Timing Chain Tensioners which can also result in these fault codes. Please refer to the related TPL/TSB for more instructions.

    When is the code detected?:
    An excessively low or high voltage from the sensor is sent to Engine Control Module (ECM).

    Description:
    The Manifold Absolute Pressure (MAP) sensor provides instantaneous manifold pressure information to the engine's Engine Control Module (ECM). The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow (MAF) sensor to detect the intake airflow.


    VAG Error Code: 19464
    EOBD II Error Code: P3008

    Fault Location:
    Camshaft Position (CMP) Sensor (G40) - Signal Limit Exceeded

    Possible Cause:
    Insecure rotor.
    Camshaft alignment.


    VAG Error Code: 16685
    EOBD II Error Code: P0301

    Fault Location:
    Cylinder 1 - Misfire Detected

    Possible Cause:
    Malfunction Indicator Lamp (MIL)(K83) active.
    Lack/loss of power.
    Hard start.
    Engine hesitation.

    Wiring.
    Ignition system.
    Fuel injectors.
    Fuel pressure.
    Running out of fuel.
    EVAP canister purge valve.
    Evaporative emission system.
    Low compression.
    Base engine problems.
    Engine Control Module (ECM).

    Special Notes:
    This feature search for engine misfire in a specific cylinder. Most of the time the cause for a misfire is a lack of combustion in a cylinder due to absence of spark, poor fuel metering, or poor compression.

    Tech Notes:
    The P0301 code means that the cylinder 1 is misfiring or is randomly misfiring. Start by checking for intake leaks an if no leaks are found the next step is to replace the spark plugs on cylinder 1. If the problem persist more tests needs to be done to diagnose problem.

    When is the code detected?:
    Engine Cylinder 1 is misfiring.

    Description:
    When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, the Engine Control Module (ECM) can determine that a misfire is occurring.
