I recently purchased a used Vauxhall Zafira Life and the engine has started making a loud knocking noise. It seems to be coming from the engine compartment and gets louder when I accelerate. What could be causing this and what should I do?
ReplyIt is possible that your engine is experiencing an issue with the fuel injectors, which can cause a knocking noise when they are clogged or malfunctioning. It is important to have this checked by a mechanic as soon as possible as continuing to drive with this issue could cause further damage to your engine.
Another potential cause of the knocking noise could be a problem with your engine's timing chain. This part helps to control the timing of your engine's valves and if it becomes loose or worn, it can create a knocking sound. If left unchecked, this issue could lead to more serious engine problems.
I experienced a similar issue with my Vauxhall Zafira and it turned out to be a faulty crankshaft sensor. This small but crucial part helps to regulate the engine's air and fuel mixture and if it is not working properly, it can cause knocking noises. I would recommend getting this checked by a mechanic as soon as possible.
