Ibiza Knocking sound

[amr_ibiza]

hey guys,
i have this sound in my car since i buy it (about 7 months) and the idiots in service center was not able to fix it or even know where it come from, so i started now to find it by myself, so i need some help with it.

this noise come from the front of the car as some thing is shaking or something like that. can it be the front suspension or what?. also there is a very annoying vibration in my pedal and the the gearbox as the clutch pedal is also is heavy it is not smooth and i dont know where it come from but they told me in service center that the vibration thing is ok.

my car ibiza 1.4 86BHP 2008

Thanx..

1.4TDI ? the clutch pedal does vibrate, the knocking sound can come from the engine, because it is noisy...does it makes the knocking sound all the time or just when you are driving? the tyres do make a lot of noise as well...

is the gas pedal vibrate too? yes it does it all the time.
also if i changed the pedals with aluminum one will the vibration disappear?

I'd guess that the OP's car is a petrol 1.4 16V FSI - that will be why he said it was 86BHP - ie approximately 86PS
