Ive noticed a loss of low down grunt recently with my Fabia vRS.The first thing Ive always looked for with turbos in this situation is an air leak in the inlet tract.I removed the engine cover and had a look at the inlet pipe running from the intercooler to the throttle body.Where it joins the throttle body there was a lot of oil around the connection and the pipe was nearly completely out!

The "O" ring sealing the joint had broken and boost had then forced the pipes apart.

A visit to the local VW dealer and three quid later,I had the new part.

It only took a few minutes to fit and now the car is back to its former grunty self!

I was told by the VW dealer that this is a common problem,so it may have been posted before on the forum.

Good post. Nice picture to show detail.

another problem there is that the pipe wears where it goes into the egr, it gets loose.
