    Fuel Additive to Help Prevent Sporadic Misfire Faults
    A Volkswagen approved fuel additive is available to help remove and prevent deposits on fuel injectors and intake valves.
    One or more of the following fault codes may be stored in the ECM Fault Memory:

    DTC
    Description

    P0300
    Random/Multiple Cylinder Misfire Detected

    P0301-P0308
    Cyl.1 Misfire Detected - Cyl.8 Misfire Detected

    Technical Background
    Fuel quality impacts the operating performance, efficiency and service life of the engine.The use of poor quality fuels may result in deposit build up on the fuel injectors and intake valves. This may result in a rough running condition, sporadic misfires, or cold start misfire faults storing in the ECM fault memory.
    Production Solution
    Not applicable.
    Service
    If sporadic cylinder misfire faults are found and a P130A Hide Cylinder fault is not present, the concern may be related to poor quality fuel and/or deposit build-up on the fuel injectors and intake valves.
    With the fuel tank at least half full, pour 1 bottle of fuel additive part number G 001780M3 into the fuel tank and drive the vehicle with the transmission in the S (Sport) selection to help dissolve any deposits in the engine.
    Note:
    Only one bottle of fuel additive is covered under warranty.
    If no concerns are found during the test drive, return the vehicle to the customer. Advise the customer to use quality detergent gasoline from a Top Tier fueling station as noted in their owners manual or in the 2014 VW Top Tier Fuel Brochure. If available, provide a printed copy of the brochure to the customer.
    If misfire faults return during the test drive, follow Technical Bulletin 2033805 Engine, Misfire Diagnostic Aid to further diagnose the concern.

    Tip:
    Volkswagen recommends Top Tier detergent gasoline with additives that do not contain metal. If Top Tier fuel is not readily available, advise the customer that to help prevent this condition from reoccurring, fuel additive part number G 001780M3 may be used approximately every 3000 miles (5000 km) to help keep the fuel injectors and intake valves clean.
    Depending on the severity of the case, the customer may need to add a second bottle of additive to help remove all deposits after driving approximately 100 miles.
    For best results, the fuel tank should be at least half full when the cleaner is added. If there is less than half a tank of fuel when added, the additive will not be as effective.
    The customer may purchase this fuel additive from the parts department, and should pour the additive into the fuel tank when re-fueling.
    For more information on Top Tier Detergent Gasoline, please go to the official website: http://www.toptiergas.com.
    Only use fuel additives approved by Volkswagen.

    TOP TIER Detergent Gasoline Deposit Control Performance Standard Revision C-February 20151.1 Performance Description. This document describes the deposit control performance of an unleaded gasoline at the retail level that minimizes deposits on fuel injectors, intake valves, and combustion chambers.
    All performance testing must be conducted at an independent, ISO 17025 accredited laboratory.
    3. Definitions
    3.1 A2LA – the American Association for Laboratory Accreditation
    3.2 Independent Laboratory – a mechanical and/or chemical testing organization not associated with the business entity seeking TOP TIER™ Detergent Gasoline status, accredited by the A2LA for technical competence in mechanical and chemical testing in accordance with the latest version of ISO 17025, General Requirements for the Competence of Testing and Calibration Laboratories.
    4. Standards.
    4.1 Retail Gasoline Performance Standards. The deposit control performance of unleaded gasoline conforming to section 4 of this document shall be met at the retail level in all grades of gasoline sold by a fuel company in all marketing areas of a selected nation. In addition, conformance to the standards shall mean gasoline sold in the selected nation shall not contain metallic additives, including methylcyclopentadienyl manganese tricarbonyl (MMT).
    4.2 Deposit Control Additive Requirements. The deposit control additive used to meet the performance Standards described in 4.3 shall meet the substantially similar definition under Section 211(f) of the Clean Air Act. Also, the additive shall be certified to have met the minimum deposit control requirements established by the U.S. Environmental Protection Agency (EPA) in 40 CFR Part 80. Lastly, the additive shall be registered with the EPA in accordance with 40 CFR Part 79.
    4.3 Deposit Control Initial Performance Standard. All performance testing and fuel composition analysis shall be conducted by an Independent Laboratory. Initial deposit control performance shall be demonstrated using the tests shown below.
    4.3.1 Intake Valve Keep Clean Initial Performance Standard.
    4.3.1.1 Test Method. Intake valve deposit (IVD) keep clean performance shall be demonstrated using ASTM D 6201, Standard Test Method for Dynamometer Evaluation of Unleaded Spark-Ignition Engine Fuel for Intake Valve Deposit Formation. Tests demonstrating base fuel minimum deposit level (4.3.1.2) and additive performance (4.3.1.3) shall be conducted using the same engine block and cylinder head. All results shall be derived from operationally valid tests in accordance with the test validation criteria of ASTM D 6201. IVD results shall be reported for individual valves and as an average of all valves.
    4.3.1.2 Base Fuel. The base fuel shall conform to ASTM D 4814 and shall contain commercial fuel grade ethanol conforming to ASTM D 4806. All gasoline blend stocks used to formulate the base fuel shall be representative of normal U.S. refinery operations and shall be derived from conversion units downstream of distillation. Butanes and pentanes are allowed for vapor pressure adjustment. The use of chemical streams is prohibited. The base fuel shall have the following specific properties after the addition of ethanol:

    1. Contain nominally 10.0% 1% by volume ethanol as measured by ASTM D 4815 or D 5845.
    2. Contain no less than 8 volume percent olefins as measured by ASTM D 1319 or D 6729.
    3. Contain no less than 28 volume percent aromatics as measured by ASTM D 1319 or D 6729.
    4. Contain no more than 80 mg/kg sulfur as measured by ASTM D 2622 or D 5453.
    5. Produce a 90% evaporated distillation temperature no less than 290F as measured by ASTM D86.
    6. Produce IVD no less than 500 mg averaged over all intake valves.
    7. A Certificate of Analysis showing both the detailed test fuel composition results and source should accompany the additive results package. This certificate should also contain the unwashed and washed gum level of the base fuel according to ASTM D381.

    4.3.1.3 Demonstration of Performance. The base fuel from 4.3.1.2 shall contain enough deposit control additive such that IVD is no more than 50 mg averaged over all intake valves. Results for individual valves and an average shall be reported. The unwashed gum level of the fuel containing deposit control additive shall be determined according to ASTM D 381 and reported.
    4.3.2 Combustion Chamber Deposit Initial Performance Standard.
    4.3.2.1 Test Method. Combustion chamber deposits (CCD) shall be collected and weighed along with IVD using ASTM D 6201, Standard Test Method for Dynamometer Evaluation of Unleaded Spark-Ignition Engine Fuel for Intake Valve Deposit Formation. ASTM D 6201 does not contain a procedure for collecting and measuring CCD. Adapting a scrape and weigh procedure developed by CARB is recommended (see referenced test method dated March 12, 1999). Results for individual cylinders and an average shall be reported.
    4.3.2.2 Base Fuel. Combustion chamber deposits shall be measured for the base fuel from 4.3.1.2.
    4.3.2.3 Demonstration of Performance. The base fuel from 4.3.1.2 treated with additive at the concentration meeting the standard found in 4.3.1.3 shall not result in more than 140% of the average CCD weight for the base fuel without additive.
    4.3.3 Intake Valve Sticking Initial Performance Standard.
    4.3.3.1 Test Method. Intake valve sticking tendency shall be determined using either the 1.9 L Volkswagen engine (Wasserboxer according to CEC F-16-T-96) or the 5.0 L 1990-95 General Motors V-8 engine (SWRI IVS test). Two options are available for demonstrating intake valve sticking tendency.
    4.3.3.2 Option 1. The valve-sticking tendency of the test fuel by itself will not have to be demonstrated prior to testing the candidate additive. The following shall be required of all tests:

    1. Test fuel shall be either the same as in 4.3.1.2 or CEC valve sticking reference fuel.
    2. Concentration of deposit control additive in the test fuel shall be at least twice the amount determined in 4.3.4.1.
    3. Test temperature shall be -20C.
    4. Three 16-hr cold soak cycles, each followed by a compression pressure check, shall constitute a complete test.

    4.3.3.2.1 Demonstration of Performance A pass shall result in no stuck valves during any of the three cold starts. A stuck valve is defined as one in which the cylinder pressure is less than 80% of the normal average cylinder compression pressure.
    4.3.3.3 Option 2. The valve-sticking tendency of the test fuel together with an additive known to cause valve sticking shall be demonstrated prior to testing the candidate additive. The following shall be required of all tests:

    1. Test fuel shall be either the same as in 4.3.1.2 or CEC valve sticking test reference fuel.
    2. An additive known to cause valve sticking shall be selected, and, when blended into test fuel, shall demonstrate valve sticking tendency as follows: (a) for the Volkswagen engine, at least two valves shall be stuck; (b) for the GM engine, at least three valves shall be stuck.
    3. Tests demonstrating performance of the candidate additive shall be conducted at a concentration that is at least three times the amount determined in 4.3.1.3
    4. Test temperature shall be -20C.
    5. One 16-hr cold soak cycle followed by a compression pressure check shall constitute a complete test.

    4.3.3.3.1 Demonstration of Performance. A pass shall result in no stuck valves during the cold start. A stuck valve is defined as one in which cylinder compression is less than 80% of the normal average cylinder compression pressure.
    5. Process to Attain TOP TIER Detergent Gasoline Status.
    5.1 Submission of Test Results. A fuel company desiring TOP TIER™ Detergent Gasoline status shall forward the test results issued by the Independent Laboratory ("Test Results") to the following address:

    AAA: Not All Gasoline Created Equal




    ORLANDO, Fla. (July 7, 2016) – New testing from AAA has uncovered significant differences in the quality of gasoline sold at fuel retailers in the United States. The independent laboratory testing compared gasolines that meet TOP TIER™ standards often marketed to consumers as having enhanced, engine-cleaning detergent additives with gasoline brands that do not participate in the automaker-backed program. Among brands tested, non-TOP TIER gasolines caused 19 times more engine deposits than TOP TIER brands after just 4,000 miles of simulated driving. Such carbon deposits are known to reduce fuel economy, increase emissions and negatively impact vehicle performance, particularly on newer vehicles. To protect vehicle investments, AAA urges drivers to use a gasoline that meets TOP TIER standards for engine cleanliness and performance.


    “AAA was surprised to learn the extent to which detergent additives impact gasoline quality,” revealed John Nielsen, AAA’s managing director of Automotive Engineering and Repair. “As advertised, tested TOP TIER gasolines kept engines remarkably cleaner than other fuels we tested.”
    In response to increasing levels of carbon deposits in modern engine designs, the Environmental Protection Agency mandated a minimum level of detergent for all gasoline sold in the United States in 1996. However, some automakers believe the minimum does not go far enough to ensure optimal vehicle performance and their ability to meet increasingly-stringent fuel economy and emissions requirements. The TOP TIER program and performance standard were developed to guarantee that program participants’ gasoline meets stricter targets for engine cleanliness.
    “When it comes to selecting a gasoline, automakers got it right – TOP TIER gasoline performs best,” continued Nielsen. “By selecting a quality gasoline, drivers can minimize engine deposits, increase vehicle performance and improve fuel economy.”
    Despite the fact that two-thirds of U.S. drivers believe there is a difference in quality of gasoline sold by different gas stations, a AAA survey reveals that Americans value convenience and price over quality when it comes to selecting a gas station.

    • Three-quarters of U.S. drivers choose a gas station based on location (75 percent) or price (73 percent).
    • Nearly one-third (29 percent) of U.S drivers choose a gas station based on a rewards program.
    • Only 12 percent of U.S. drivers select a gas station based on whether the gasoline contains an enhanced detergent package.
    • Nearly half (47 percent) of U.S. drivers do not regularly buy gasoline that contains an enhanced detergent additive.
    • Men (44 percent) are more likely than women (26 percent) to regularly buy a gasoline that contains an enhanced detergent package, as are baby boomers (41 percent) compared to millennials (32 percent).

    “Americans are six times more likely to choose a gas station based on the price of gasoline rather than the quality of the fuel,” continued Nielsen. “Since TOP TIER gasoline is widely available and only an average of three cents more per gallon, AAA urges drivers to reconsider their priorities when selecting a gas station.”
    To ensure a gas station sells a high quality gasoline, consumers should research the fuel options near them. According to TOP TIER, one-third of gas stations meet the TOP TIER standard for fuel quality. Retailers interested in participating in the TOP TIER program can find additional information here.
    “Fortunately, consumers can reverse some engine deposits simply by switching gasoline brands,” said Greg Brannon, AAA’s director of Automotive Engineering. “After a few thousand miles with TOP TIER gasoline, performance issues like rough idling or hesitation during acceleration can often be resolved.”
    For testing purposes, AAA selected TOP TIER and non-TOP TIER gasolines from a southern Texas market that represents the type of gasoline sold across the majority of the United States. To measure intake valve and combustion chamber deposits, AAA engaged the services of an independent International Standards Organization 17025 certified engine testing lab to perform an ASTM International standard test on fuels.
    To evaluate consumer gasoline preferences, AAA contracted with a national research company to perform a telephone survey of 1,002 adults (18 years of age and older) living in the continental United States. Survey results are an accurate representation of the total continental U.S. population, 18 years of age and older, with a margin of error of +/- 3.1 percent at a 95 percent confidence level.

    As North America’s largest motoring and leisure travel organization, AAA provides more than 56 million members with travel, insurance, financial and automotive-related services. Since its founding in 1902, the not-for-profit, fully tax-paying AAA has been a leader and advocate for the safety and security of all travelers. Motorists can map a route, identify gas prices, find discounts, book a hotel and access AAA roadside assistance with the AAA Mobile app for iPhone, iPad and Android. Learn more at AAA.com/mobile.

    Yeah I'm sure top tier gas and VW's additive do a ton for direct injection carbon deposits on the intake valves But it's easier to tell the customer that someone else's gasoline is the issue than to own up to the problem and offer free lifetime cleaning on all FSI engines, isn't it?

    Yep time for a change in test engine

    Soon as I started reading the test criteria I was thinking this is outdated, and no matter how much Shell V power I pour down its neck there is going to be no difference to my carbon build up.

    Same as all the snake oil treatments for carbon cleaning, another bloody rip off.

    Ahhh yup........because a stratified engine has fuel injected directly to the combustion chamber.
    It doesn't have a scrubbing or washing effect on carbon, & which is pushed into the intake port from dirty fire from the valve over lap point.

    No matter how many additives you put in the fuel you can not defeat this in the stratified process.

    Agree 100%, yet people who own especially a B7 RS4 keep searching for a way to prevent carbon buildup and just won't listen when long term owners (I owned one for 10 years) tell them that carbon buildup happens, so any cleaning they do is pointless and would need to be repeated every 5000 miles or so.

    I think two ways can help this problem..............

    Chemically remove and fog the intake every 10 K.
    Use a non synthetic oil changed more frequently, & that sticks to the cylinder walls better, so you don't lose the compression by means of the oil being contaminated by blow by gases/fuel and water or remediated into the combustion process.

    When a oil remediation process uses a "labyrinth"............ you have a problem!
