Hi!

 

I have a Skoda Fabia 1,2 from 2003 which has been driven around 62 000 miles. 

 

Last year I had to change timing chain with and some other expensive activites so this car has cost me a lot...

 

Now suddently when I press gas pedal the car sounds like a tractor/moped/old american car. When I do not gas it sounds as usual, so probably something wrong with the exhaust system in the engine I suppose.

 

I found out that there is a loose hose in the engine room. Please see the attached images. I fits very well in a tap a bit above. Do you think it is supposed to sit there, what good does it do and could hose has casued some bad problems with the car?

 

Thank you very much for your help and adivce.

 

 

Yes, that is the engine breather hose and it should be attached to the air filter.

Yep defo should be attached

EGR valve filtered air hose.  Connects as you think to that 'tap'.  It will not do any rapid harm to the valve if it isn't connected, but long-term it would suck in particulates from the atmosphere that would accelerate wear of the EGR valve guide.

 

The noise you're hearing is not related to this pipe, but most likely your flexible coupling in your exhaust front pipe is broken.  Front pipe replacement isn't too difficult if the next piece back is in sound condition.

I went with the car to a garage and they told me it was the EGR valve that was broken and needs replacement. 

 

I replaced it in march last year at another garage, so I'l go back to them again to have it fixed on warranty.

 

Thank you for your fast and help and information!      

Print out and show them this document when you take the car back to the garage that replaced the EGR. Maybe they didn't do the suggested ECU software update, so the new valve has been damaged as shown in the left-hand picture. That would explain the noise you're hearing, if the exhaust flexi joint is OK.
