Ford Fiesta 1.4 TDCI - Intermittent power loss above 2k RPM - FiestaMan01

Hi all,

I've suddenly noticed that when driving above 2k RPM, my car expereinces intermittent power loss. When keeping the accelerator level, the car jerks about, as the power drops and rises. This power drop/increase gets worse as I drive faster. I've also noticed that there is a suction noise when putting my foot down, which I'm assuming is the air intake.

With the above syptoms in mind, I'm wondering if there is a turbo issue here. I will ofcourse eventually take the car to the garage, but am wondering if anyone has any ideas/advice?

Many thanks!

Check for air leaks between the turbo and the inlet manifold, especially around the intercooler. Also check for any restrictions in the air intake between the air filter box and the turbo. Make sure the air filter element is clean and not full of dust and dirt. Check the EGR valve to make sure it's not stuck open, even partially. If it is then the engine will draw back too much exhaust gas, and this will affect engine running and performance.
