Right, can't find the location of this pipe in the engine bay of my 1.8T VRS. The part number is 06A 145 790 C, thought I would fit it myself to save some money but it would help if I could find where the flaming thing went?

If I'm not mistaken than that pipe is located underneath the engine, and only accessible if you have the car on a bridge. It looks suspiciously like the pipe that was replaced under warranty on my octy a while back.

Its on the drivers side at the back of the engine. If you pop the bonnet and look down the back of the engine on the left hand side you'll see the shielding surrounding it.

This pipe was replaced on mine due to 17705 errors

I had photos here http://www.briskoda.net/forums/octavia/fault-codes-17705-17545-a/7798/?highlight=17705 but the gallery ain't working. Although someone else has a pic up.

yep, back of the engine, goes from the turbo to the bent pipe that feeds the intercooler. lots lots easier to get at whilst on ramps.

Is this replacement a DIY job? If so I might change mine too. £39.43?

its not hard as long as you can get at it. ross removed it, cleaned it and refitted it on my car in about 60 seconds but that was with the car 7ft high on ramps. would take a lot longer if it was on the ground.

Dennis,

Well worth it for that price as it's a pain in the proverbial for fault codes. Be careful as the clip that holds it on must go back in the right place or it will be blown off when at full boost.

The new ones have a twin lip seal design rather than the old single lip o-ring, thats why they were replaced.

Just ordered one of these in the hope it'll solve the 17705 I've had since I've owned the car. VAG have 40 of these in the UK BTW (according to my local VW dealer).

To those who've changed it - did you notice any difference other than a lack of fault codes, when the pipe was changed?

Fitted this last night and it took less than half an hour, including jacking the car etc.

One thing that makes it easier is to release the intercooler pipe in the wheel arch. If you look in the offside wheel arch, you'll see the flatish metal pipe, at the top its held onto a bracket with a nut. Removing this nut will allow some movement and gives a bit of movement on the other side (where this pipe is)

The biggest PITA for me was the jubilee clip on the bottom of the pipework, it was a little corroded on my vehicle.

Also worth noting that the heat shield/sleeve on the part shown above is held on with 3 poppers so it comes off easily. Its not symetrical in shape so it only fits one way round.

As people have already said, make sure the spring clip at the top goes on the same way it comes off.

Cheers for the heads up about the intercooler pipe Goochie, gonna hopefully fit the pipe on Monday with my brothers help. Was it easy enough changing it under the car as we were just gonna jack the car up? Have you noticed any difference since you fitted it? Any evidence on the old pipe of any leaks?

I parked the car with one side on the kerb and jacked the other side up and put an axle stand under it.

One annoying thing is that my trolley jack now doesnt fit under the car now its lowered - I have to use the jack supplied with the car to lift it a couple of inches to use the trolley jack

It really is an easy job, I opened the bonnet to let some light through. The pipework connected to it is cold but the exhaust is close by so if the car is warm, be warned.

Once you're under the car and looking up the back of the engine you'll see it straight away, with the intercooler pipe free to move, and the bottom jubilee clip on the pipe released you can easily slide it off the bottom.

When you fit the new pipe, make sure the bottom slides down to the lugs on either side of the intercooler pipe. The top just pushes straight in.

I went out of the house to start the job just as Neighbours was coming on - I was back inside having done the job, washed my hands and put the tools away before Neighbours had finished.

Use a flat screw driver to release the clip at the top, when it comes to replacing this clip, just push it over the pipe and it'll clip into a notch on either side.

There is one thing I would do differently, once the old pipe is removed, put the heat sheild thing back on it, using the new pipe as a guide. That way, when you come to put the sheild on the new pipe under the car you wont have to fathom out which way it goes.

TBH I've not noticed any difference at all, the only thing I did see was the seal design has been changed (as Ross said).

I'll get the fault codes cleared at the weekend and see if they re-appear over the following week.

Thanks for that, gonna fit a forge dump valve and green panel filter at the same time as replacing this pipe, so hopefully I will see some improvement on the breathing side of things!

Two weeks after changing this pipe it seems I've cured my intermittent 17705 fault code

Very happy as its been bugging me for the last 2 years.

I had this on mine, one of the first in the UK to suffer from it. IIRC I did post it on here.

Good to hear. I had to lower my trolley jack 70mm to get it under my car. (actually I was just v.lucky that it still just slid under the sill)

Mine wont even go under the sill - I have to use the screw jack to lift the car to get the trolley jack under perhaps I just have a tall trolley jack ?

I've seen this fault code 17705 on here a few times and was wondering what the fault was and if it would cause any other problems. On a side note does anyone know of anybody with vagcom near wolverhampton.

Deano.

Loosing the fault code is the only improvement I've noticed. It is clearly a recognised problem as you can see the seal has been changed from a single O-ring to a double lip seal. (as someone here said)

Low entry trolley jacks are expensive. I got mine for £20 from that well known car accessory out of town superstore and like yours, it doesn't slide under. Recommended tip for you Goochie. Get yourself down to your local timber yard and purchase a couple of lengths of 6" gravel board. Saw this up in to progressively smaller length and screw them together to make a staggered ramp to the height required. To use, place infront of wheels, drive up (needs only be 3" high at the most I would guess so you ain't going to break anything if you roll down the other side) and there you go - trolley jack fits under. (NOTE make sure the wood you use isn't likely to split under the weight and put a screw or two through your tyre )

Huzzah for this thread as I now know which pipe went pop

Is that the pipe for sure as there is another 2 pipes that join onto that.

Yup it's the one with the heat shield!

Hi all. Has anyone got the part number for this pipe? For

Errr have you tried reading the full thread mate??? It's on the first post
