Identify a part for me: Passat Exhaust System

ShayK1

01 Passat 1.9Tdi 130Bhp
Where the exhaust pipe comes out of the engine there's a steal mesh pipe only about 6 inches long or so...

Anyone know what its called?
Or where I'd get a break down diagram of the exhaust system ?
or how much the replacement part will cost me?

Thanks lads.

That's called a flexi pipe.

ShayK1

that's it exactly. Thanks.
Are they expensive or difficult to replace??

This part allows for movement between the engine and exhaust if this part was not on your car it would be a very vibrating ride! I fitted an exhaust pipe on a caddy(same engine) and I can remember it came with the catalytic converter. Now they are expensive!
I'd say you can get them separate but it will require cutting and welding etc.
As for the name I'm not really sure. I thinks its just called the wire mesh.

Yeah, they are pretty expensive - stay away from a vw dealer!

I worked for a bosal main dealer and they supplied "weld in" replacements - it costs about €90 for the flexi-pipe and whatever labour to remove the exhaust and replace the section.

If you can find a bosal dealer, they can give you a price for fitting, or alternatively they can give you a price to replace that section of the exhaust.

You can buy them in various diameters for welding into existing exhaust. Cheaper than replacing with a genuine part.

is it just a matter of opening 3 bolts at the engine... and splitting the pipe where ever the first split is... then cutting out the old one.. welding in a new one and re-fitting it??
Will I need any gasket or sealer or anything when re-fitting?

I know at least 2 guys that are very handy with a welder so that shouldn't be a problem...

Ya, that's more or less it - check you get the correct diameter pipe first though!

If you get a tube of exhaust paste - try cleaning down the gasket and joint on it with a wire brush and putting a little paste on it when you're putting it back together.

suggests you can get a bolt in replacement...??

ShayK1

rang bosal ireland. looks like advance pitstop can order in the replacement part for me once they measure it and stuff. sweet!!

ShayK1

ok, now I'm confused.

Bosal asked do you just want the flexi pipe?
I said yes. She said you can get it from one of our agents once they measure it.
So, rang advanced pitstop (the closest bosal agent to me)
Dude told me you can't just get the flexi pipe you've gotta get the cat too....??

Any suggestions on what to do next?

Captain Slow IRL

I didn't realise the cat and flexi pipe were on the same section.

You can get the flexi piece separate, whether he doesn't know or he's trying to push the most expensive item on you, but having said that, you'd be better off buying the cat as the pitstop guy recommended. There is a lot of stripping to remove that particular piece of pipe, and the flexi piece is very small - there isn't a lot of room to play with when replacing it.

That's pretty much what they told me in advance pitstop yesterday when I called in.
So.. They can get the replacement and fit it for €400
Or... I can get the replacement myself from http://www.cat-direct.ie/ and fit it myself for €220

I've no problem fitting it BUT I'm not sure I'll be able to get the 3 bolts out of the manifold ?
With that much heat they HAVE To be pretty tight and akward to get at??

Captain Slow IRL

You have to get the 3 bolts from below. (you'll need a lift!) You also gotta strip out a fair bit around the turbo and airbox to be able to remove the cat. If you're confident, go for it - otherwise, pay the extra to save you the hassle and stress!

I have a pit (albeit, covered by copious amounts of crap) but when you say I've to strip out stuff around the turbo... Does the cat have to come out the top? Will it not go out the bottom??

I'm gonna get under it tomorrow and have a good look around.. then I'll make my decision.

ShayK1

Decision made and part ordered from www.cat-direct.ie for €200.28 incl. vat & delivery

I think it'll come out the bottom. Not 100% but I think it will. I'll update this again next weekend after I replace it.

Thanks for the help and advice lads (special thanks to Land9)

Yeah - the VW catalogue lists this flexipipe as being part of the section that contains the catalyst.

I assume it's the flexipipe just before the cat in the image below (item 1).

Yeah that's it. I was trying to get a weld in replacement but I was told I couldn't get one for the passat.

I've ordered this....

As far as I can remember, it comes up the top - best of luck!

ShayK1

So, its done!!
Got the part on thursday and changed it yesterday and it did indeed come out the bottom.
There's a mount that's held on with 3 allen head bolts and 2 hex bolts that came out very easily and allowed the cat to come out. It wasn't as easy to put back cause there was a new exhaust pipe in the way but I managed.

For anyone doing this:

Its far easier to join the cat and the pipe first and then put it in place than trying to join it with it in place.

It took me awhile to do it but at least I saved 200 quid.

Thanks again for the help and advice.
