Hi everyone,

I have an issue with my Skoda Superb 2.0 TDI 190 (engine code DFC).

When I press the clutch pedal, I can hear a rattling / knocking noise, like something is loose or hitting inside. As soon as I release the clutch, the noise disappears completely.

The car also slightly shudders when pulling away, especially when the engine is at operating temperature.

Important note: the clutch kit and dual mass flywheel (Sachs) were replaced around 5000 km ago.

So I’m a bit concerned whether:

- the dual mass flywheel could already be faulty,

- something was not installed correctly,

- or if this could be something else like a release bearing or gearbox issue.

Has anyone experienced something similar?

Any advice would be appreciated.

Thanks!

More details?

Does it start as soon as you press even lightly on the clutch, or only when fully depressed?

Does it disappear in any specific gear?

Does it do it in neutral and in gear?

Does it match engine speed, what about when rolling? Eg fast coasting at say 40 and engine at idle?

Could be either of these. Need more details.

Throw out bearing normally makes some noise if slight pressure on it, spigot bearing does when clutch actually disengage.

When I was throttling for about 30 seconds, the sound disappeared. As soon as I pressed the clutch pedal, the sound started again. When I depress the clutch pedal, the sound disappears, like you heard in the video.

I had driven 300 km and the car was hot. As soon as I arrived at the parking lot, the car started making that sound and I had to leave it there. The next day there was no sound, and I have been driving for two weeks now without noticing it again. However, when pulling away, the car shakes a little bit, like the clutch plate is not catching evenly.

The sound appears in neutral and in first gear when the clutch pedal is halfway pressed. I didn’t drive the car at that moment, so I can’t answer the other questions.

Thank you for your time!
