Power loss

Skoda Octavia 2004
I own a Skoda Octavia and, since its 12000 miles, the engine loses power when overtaking a car. The flowmeter and the turbo's pressure valve as well as its unions have been changed, but the car keeps losing power. The turbo is about to be replaced. There are many interior noises as well which are certainly annoying.

Hi, try changing the forced induction pressure sensor.

Power loss

Skoda Octavia 2007  245000 miles
When ascending, a spiral light turns on and the engine loses power considerably. After some minutes, the car suddenly recovers but fails again a while later. Occasionally, the pump light indicator turns on as well. What can I do?

From my experience, I recommend you to change the oxygen or lambda sensor and the spiral light will disappear. You should first check that none of the light bulbs is blown. If they are all alright, change the brake valve located in the brake pedal. Hope my suggestions help you solve your problems.
