FUEL/PROPULSION SYSTEMOn going fuel system issues that pose significant safety risks, suggest potential design or manufacturing flaws, and are impacting vehicle performance. The primary component affected is the fuel injection system. I have had to replace the fuel leak detection pump, spark plugs, and ignition coils multiple times, as fault codes have repeatedly appeared even after repairs, indicating a persistent failure within the fuel injection system. Additionally, I believe that the use and recommendations regarding fuel grades are contributing to the problem. I was informed by a Volkswagen employee that I should have been using 93 octane fuel; however, I was never provided with this guidance at the time of purchase. The vehicle’s fuel tank clearly indicates the use of 87 octane fuel. This discrepancy raises concerns about whether consumers are adequately informed about the proper fuel to prevent issues. The lack of clear guidance on fuel grade requirements appears misleading and could be viewed as potentially deceptive. My vehicle has begun riding rough and shaking while driving. I have been informed that I now need a decarbonization (decarb) engine intake service and a fuel injection service to address these new symptoms. These issues further indicate that there may be underlying problems within the fuel and intake systems, possibly related to the ongoing deposit buildup and improper fuel use. The failed fuel leak detection pump, affected fuel system components, and the recent service needs are available for inspection and can be provided upon request.
The malfunction of the fuel injection system and the fuel leak detection system substantially engine failure while driving which could endanger the driver, passengers, and others on the road.The issues manifested as the vehicle would jerk later my engine light came on, prompting me to seek repairs. It has not yet been formally inspected by the police, or insurance representatives, the mechanic’s diagnosis confirms the malfunction.
