How do I know if my 1. TDI injectors are bad?
The first noticeable symptom is usually uneven engine running, especially at idle. This can be caused by incorrect fuel atomisation, leading to incomplete combustion. If you notice that your car is losing power, especially during acceleration, this could also indicate a problem with the injectors. Fuel injector problems can eventually lead to a breakdown, or in extreme cases, an accident if your engine fails while traveling at speed on the highway. Be sure to treat the problem before that happens.As the engine misfires, the engine can quickly overheat and pre-ignite the fuel mixture. A damaged fuel injector will not only causes issues with driving, but the effects will persist even as the engine idles. Instead of a smooth engine idle, it will be rough and irregular when the fuel supply is abrupt.When the engine is denied fuel because an injector is going bad on one side, the matching cylinder will not fire. And the result will be continuous interruption or vibration of the engine when you are driving.Increased Fuel Consumption: Faulty injectors can cause the engine to burn more fuel than usual. Smoke from Exhaust: Excessive smoke from the exhaust, particularly black or gray smoke, can indicate injector issues. Misfire: The engine might misfire, especially under load or at higher RPMs.
How long do 1. TDI injectors last?
