How often should the fuel system of Volkswagen Tiguan be cleaned?
2 Answers
Volkswagen Tiguan's fuel system should be cleaned every 20,000 kilometers. Reasons for cleaning the fuel system: After the fuel system has been in operation for a period of time, carbon deposits and gum formed by combustion will adhere to the fuel injectors, causing sticking or even clogging. Impurities and dust in the air and gasoline can also lead to poor fuel flow or blockages, ultimately forming carbon deposits and deposits on the fuel injectors (carbon deposits will also form on valves, combustion chambers, and intake pipes). Necessity of cleaning the fuel system: If the fuel system is not cleaned for an extended period, carbon deposits and deposits can clog the fuel injector needle valves and valve holes, affecting the performance of the precision components in the injection system. This can result in poor fuel injection, inadequate atomization, or even no injection at all. Consequently, the car may experience unstable idling, increased fuel consumption, poor acceleration, and difficulty starting.
My Tiguan has over 70,000 kilometers on it. The maintenance manual suggests inspecting and cleaning the fuel system every 30,000 to 50,000 kilometers. Last time at the dealership, the technician mentioned it depends on driving conditions. For someone like me who drives in the city every day, often idling in traffic, the engine is prone to carbon buildup, so cleaning every 30,000 kilometers is safer. During a dealership promotion last time, I had the fuel injectors and throttle body cleaned, and when replacing the fuel lines, we found the fuel filter was a bit clogged. If you're used to filling up at smaller gas stations, or if your car feels sluggish and fuel consumption increases, it's definitely wise to check early. After the cleaning, the throttle response improved noticeably, and overtaking on the highway felt much more powerful.
