exeo TDI rear exhaust box

[Huddie]

My exeo 2.0 TDI sport was in for its annual service last week and one of the recommendations on the cars health check was the rear exhaust box. Its heavily corroded but not blown. The seat dealer is quoting £377 which I thought was a bit pricey. So I asked my mate who works in a tyre and exhaust place to price me one. He recons there's no one making them yet and I'll probably need to get it from the dealer when it blows.

Has anyone had to replace their rear box yet or can anyone lend some advice where to get an alternative cheaper than £377. ??

Cheers

Just visit an exhaust specialist and get a stainless steel one made on your car, it'll probably never need changing again. Thats what i'm gonna do when mine goes.

Can you not just get the equivalent a4 version ?

 

[taffybloke]

There does not seem to be an A4 version. They are mostly twin silencers or single/down turned tail pipe. It is unusual for diesels to rot exhausts.

the last one I changed was on an Ibiza about 12 years ago. Just sold a passat 08 with 90k and still have an 05 Xtype with 140k with original exhaust. Hope the exeo one is not made of crap materials.

As you say no one seems to be making one yet.

anyone have an update on getting a bock box replaced ? just noticed that mine has heavy corrosion .F1 have told me they are only supplied by the dealer
thanks

I have now sold my exeo but after discussing this and showing it to a mate who worked at an exhaust & tyre shop. He inspected it and it was only the first layer that was rusting so we just pulled that of and the 2nd layer was like new. The dealer never mentioned it in the health check for the following service. I hope this helps.

Returning to may car yesterday (2012 TDi ST estate) and noticed a large piece of corroded sheet metal hanging down off the rear exhaust box. On closer inspection it was a piece of "outer skin" covering the internal back box. The underside of this outer skin was all but corroded away so I cleaned back any loose rust.

Interesting to note was a big VW emblem now revealed on the inner silencer skin. Does this just mean the box was made by VW or that it's also compatible with other models of car?

Thankfully the inner box is still intact and not blowing (for now)

It wont blow they all do it
its just a skin they put on
the box is actually stainless steel underneath
they put the extra skin on for insulation purposes but in the real world it makes no difference at all
all is good just forget about it

Cheers Paul. It's still an odd thing to do. Maybe it's just to cover the VW logo.

Oh well this is nice to hear its just outerskin, mine is heavily rusted too and just hanging there barely, might just aswell take it off before it comes offs and flies to someones window

You might well be right , considering its a nice shiney stainless box underneath

Cool. Mine is the same, so looks like I'll be pulling off my cover too

Hi all, do you know if this will work? All the Audi variants have twin exhaust, so I thought why not look at the Passat B7?

I can't post the link because I am new, but the product is a miltek exhaust code: SSXVW197

Which fits Volkswagen Passat B7 2.0 TDI 140 & 170 (Saloon / Estate / CC) 2010 and later

My local Seat are quoting over £600! :-O

I have not looked at the exhaust yet, to see its level of corrosion but I will have a look soon.

I have a Seat Exeo ST 140

Thank you for your help.

This is only a comment.
I have never had to replace an exhaust since the last century.
Had Japanese cars and Seat cars.

Hi Andy,

Well this is my first German car. I have only had French cars to date. (You can laugh). I have had to replace two exhaust one fell off and the others silencers rattled (internal debris) so that had to go.

I have looked under the car today and it is a exhaust outer skin that has rusted the exhaust under that is fine. So I will just rip that off. Save any spend on a new exhaust.

Thank you,

Steven

My brilliant Exeo has now done 92k miles. It's been a great car. My emissions warning light came on about a week ago and I assumed I needed some kind of egr sensor or other expensive egr related component. I was in the process of organising a trip to the dealer today when I saw this thread and checked under the car. Sure enough the outer skin on the back box had corroded and it was hanging down. I did as others suggested and ripped it off. The main box underneath still looks perfect. Guess what - the yellow emissions light has disappeared - magic!

You'll find that even a relatively short, high revving run on the motorway will clear the DPF fault light by burning off the particles that are clogging the filter. It's something I have to do on a monthly basis due to regular short journeys. I used to worry about it but now just plan in a regular "burn off" trip.

It's just coincidence that the light didn't come back on after you ripped off the rusty outer exhaust box. Burn off had probably completed on your last run out.

Short lived positivity! 23 hours later and the yellow emissions light is back. Need to find out the error code. I thought the CR engines didn't suffer from DPF regent problems like the PD engines. Is that wrong?

CR suffer constant regens just the same. It's just something you have to live with.

Once its up to temperature, take it for a couple of miles down a motorway at about 3000rpm. This generates enough heat to burn off the collected particles in the filter. The DPF light should clear itself and stay off for at least a couple of weeks.

Just an update on my "rotting" rear exhaust box. Just lately it's started vibrating at low revs. Turned out to be the upper outer skin vibrating against the heat shielding.
After purchsing a small tube of silicone grease and a pair of exhaust hanger puller hooks, I managed to lower the exhaust enough to remove what was left of the outer skin.
Job done!
