I have a Ford Fiesta LX 2012 (154,000k on odometer) that has had a loud tapping noise coming from the motor. It has the 1.6L Petrol engine, but the tapping makes it sound like a diesel.

The engine starts first time, it does not use water, or burn oil and it has not any oil in water and vice versa. I am experiencing no warning lights.

The only real issue is that it is quite sluggish when the air conditioning is on, and in summer it feels sluggish and intermittently stalls while idling, but it starts straight back up. The colder the weather the better the engine runs.

I had a mechanic look at the issue and they have told me that the engine needs replacing because it is worn out.

I'm tossing up whether it is worth replacing the motor, or if I should get another mechanic to take a look in case it is something that can be fixed without replacing the motor.

Has anybody else experienced this type of issue with your Fiesta? and if so, what caused the problem?
