What is the most common issue with the Vauxhall Mokka's engine?

I've been experiencing some trouble with my Vauxhall Mokka's engine lately. It's making strange noises and doesn't seem to run as smoothly as before. I've checked the oil and it seems to be at a normal level. What could be the underlying issue?

Based on your description, it sounds like the issue could be with the timing belt. A worn or damaged timing belt can cause strange noises and affect the engine's performance. It's important to get this checked and replaced if necessary by a qualified mechanic.

Another common issue with the Vauxhall Mokka's engine is a faulty spark plug. This can also cause strange noises and a decrease in performance. Have a mechanic check your spark plugs and replace them if needed.

Sometimes, the issue can be with the fuel injector. If it's clogged or damaged, it can affect the engine's performance and cause strange noises. Try using a fuel injector cleaner or have a mechanic clean or replace the fuel injector for you.
