As a first time Octavia owner i hope someone can help - advise?

How is the rubber intercooler pipe that goes from inside the wheelarch secured to the stainless steel pipe on the engine? Looks like a circlip? My pipe will move 1cm up and down and i am wondering if it is sealing properly as i have a distinct power loss since last friday along with more "spooling up" noise from the turbo now.

Thanks

Pete

Looks like you've accidently posted this in the fabia forum rather than the Octavia one though!

There should be flattish metal pipe directly behind the wheel which joins to the turbo via a rubber pipe behind the engine and joins to the intercooler by a smaller rubber pipe (also behind the wheel) see below:

If you jack the car up and remove the drivers side wheel you can check if the clips are secure and replace them with jubilee clips if need be. That rubber pipe popped off on mine the week after I cleaned the intercooler (didn't tighten the jubilee clips proprly!) and it sounded like a spitfire :eek:

Does your car have the modified hose mentioned in the thread below fitted? If not, it might be worth considering.

To answer the first question it is not a circlip but it is a similar idea. (usually put on upside down?)

The pipe that goes from the flat metal one in the wheelarch up to the metal pipe behind the engine attaches to the bottom end with a Jubilee style worm drive clamp (this is a common place for Air to leak - you will have an oily deposit on the outside of the squashed pipe if its leaking here), the other end has a metal band around which there is an o-ring seal. This pushes into the pipe that comes down the back of the engine and is secured with the clip. on the early version pipe the metal lugs(2 of them) that the clip locates in were pressed out and used to get bent out of shape, this can cause the clip to come loose and the pipe to leak.

Picx borrowed from a VW Vortex post VWvortex Forums: Charge Pipe (Turbo outlet to pancake) - Safe to use sealer??

The revised pipe has stronger lugs and also the o-ring is a different design.(not infallible but much better) picture is of the C revision they are now on a D. I know because I recently did mine.

(if you want to buy one mine is for sale as I have used my old A revision pipe and modded the connector like below - it was only on the car for a week)

If you need a ny more info PM. I have done this two weeks ago so if you have any questions it is still fresh in my mind..

HTH.

beat me to it Denis! maybe I should type less

LOL - I thought you were on about the lower pipe...oops!

Thanks to everyone who posted a response - i will let you know the outcome.

Then i can get onto the more important business of lowered springs etc

Any update on this one Wedgeman?

Yes, well i managed to get the garage who sold me the car to pay for the pipe if i fitted it myself. It had been into 2 garages arranged by the dealer i bought it from, to investigate the power loss. One of which was a VW main dealer and both said there was no boost loss or power loss as there was no codes recorded.

So yesterday i changed the pipe myself, the old one literally pulled out of the join and it looked clearly like someone else had "fiddled" with the pipe before. Anyway new pipe on and still no return to full power :thumbdwn:

I am now looking into replaceing the dump valve as for a couple of days after the initial loss of power its started making that "tshhhhhhhh" noise after gearchanges something it has never done before or since, i wonder whether that means it has failed??? I know this is what dump valves do on most cars but the factory ones are normally pretty much silent(?) and i've not since managed to get it to make the noise?

Any ideas anyone?

If your car has the standard Black Bosch DV and you can hear it then it is failing..you can either replace it with a standard one or upgrade to the Forge 007P.. you can test the DV by taking it off, push the pluger up inside and hold, put your thumb over the top and then release the plunger. If it holds it is OK if it moves then it is leaking.
