Chaps, I've got an old OEM B8 Avant exhaust in my garage, from my previous car (it's cut in half so I could get it in my car after it was replaced).

Is there any value in sticking it on ebay, or listing on car sites, or is no-one going to be interested and I'm better off taking it down the tip?

Only one way to find out,,, hehe you may find someone that’s selling their car without a Milltek or something similar might have it off you to put back to standard.

Yes, anyone that bought a non-resonated Milltek and now cannot sell their car will be after it wink

Was it cut somewhere sensible? You can normally buy sleeves for not a lot of money that are a lot less aggro to fit than having it welded.

Thanks folks. Yeah, guess I just take a picture and stick it on ebay and see! Had a look last night and there's some on there for big money (£300+), but of course they haven't sold, which I guess says it all really about those prices.

Interesting to see some of the sellers are places that sell "upgrades" (Millteks etc). I had always assumed that when they removed your exhaust (and didn't ask to keep it) that they just chucked them in the skip, but looks like they sell them on ebay! Nice little earner (if they sell)…

It's just cut in the middle somewhere, can't remember the exact point, it was a while ago, and it's behind a load of stuff in the garage. But yep the guy at the time mentioned I could just sleeve it in the future. Not gonna bother doing anything with it, I will sell as is, easier for someone to collect if in 2 parts, and I can't be bothered to post either, so it'll be collect or nothing.

There’s always people that want a Milltek, if you sell it with the car you’ll get nothing back, if you take it off you might get another £500 for a full S4/5 system.

I've only got the OEM exhaust, the car went a long time ago, but yeah others might want to do the above and hence want the exhaust.

I know of a tuning place that does a lot of Milltek fitting - they have piles of OEM exhausts round the back of the workshop, on the off chance someone asks for one to return a car to stock. Every few years they get the scrap man round to weigh them in - that's their intrinsic value.

I honestly can't remember the last time I changed any part of an exhaust due to corrosion - must be a minimum of 15 years ago, and my cars are generally owned until they're 10 years old or thereabouts.

Just been quoted £800+ for a thermostat at Guildford Audi... (they have my car for a major service, mot and fuel rail recall). I got the figure down to £750 but then I said they might as well do the water pump, so they added another £120! Car has only done 23k and it’s a 2015 model.

As a result, I have booked in at SE Autoworks by Guildford station. Thermostat and water pump (genuine Audi parts) for £590.

Given them my d2 S8 random jobs also.

Has the thermostat failed? I’d be pushing for some kind of contribution from Audi on a 4 year old car with that low mileage. Has it got full Audi service history?

You’ve got me twitching now, mines in for the fuel rail on Wednesday, is yours the newer CREC engine?

I'd agree thermostat failure on a car that age is pretty unusual. Did it fail open or shut? Underneath the s/charger, so a sod to get to, I suppose. Still a year of extended warranty to run on mine, which is reassuring... smile

I had CREC fuel rails done a couple of weeks back. They ended up keeping it overnight due to only having half the number of seals required frown
Still not showing as done on the MOT recall checker, and I had a letter from Audi UK yesterday asking me to book it in for the recall work.... Left hand, right hand.

It’s a bit rubbish really isn’t it, 4 years old and 23k miles. This is the cars 2nd major service (+ 1 oil and 1 brake fluid change) in that time.

I have never seen the temp above 90, no puddles on the driveway and checked the coolant levels a couples of weeks ago. Never topped it up since i’ve had the car. Will check on arrival.

Update you shortly!

I'd echo the above that that's v low mileage for the thermostat to require replacement (are you looking at this because of the fuel rail recall?). Ours failed at about double the mileage of yours, and a good bit older. We got some early warning (temp gauge started wondering from bang on 90C, max fans running after not that much driving, before it finally failed shut and the temp shot up!) when it did finally fail, the engine was stone cold to the touch despite running on the motorway prior to the total failure (coolant was boiling in the header tank). No long term harm done (been a good couple of years since IIRC)

I'm pretty sure I didn't bother having the water pump changed as it's on the front of the engine and accessible anyway - front end needs pulling into the service position to access it, so also wasn't worth doing the s/c drive belt at that point.

On pre-facelift cars the one job worth considering while it's in bits for a thermostat with the s/c off is the PCV, which is also underneath. It's not an expensive part, and requires a software change to the ECU, but reduces oil consumption.

Book time for labour for s/c removal is something like 6.5hrs.....

Fuel rails also under the supercharger, I guess. In which case if the recall is needed thermostat replacement should only be a 30 minute job?

Thanks Guys

Is that right that the fuel rail replacement would need the same parts removing? absolute turds if so!

So I called up and asked for a video (as they do whenever they quote parts these days) and they said they can't see the leak but the coolant level was low. Then later he said he could see the leak when they were doing the fuel rail job but not now its re-assembled.

Not best impressed and a very quick way to stop me using the main dealer if something dodgy is going on.

I have requested Audi to contribute towards it so they are sending information off to Audi UK, apparently.

IME they don't seem so keen on making 'contributions' any more.

I had several instances of 'goodwill' with my previous Audi but on my S4 the dealer found a mild oil leak at the rear of the gearbox whilst in for MOT (funny that they didn't notice it a few weeks earlier when in and still under warranty), they wanted £120 to examine/diagnose the problem and didn't appear willing to consider any goodwill despite the low mileage, FDSH and that I just bought a Q2 from them for the Mrs.

I took it to a specialist/independent for the service & gearbox repair (basically apply the correct amount of gasket sealant where Audi had skimped during build) I also had an early (at 30k miles) gearbox oil & filter change for peace of mind.

The total bill was significantly less than the Audi quote for the servicing alone and I've no idea what Audi might have charged on top of the £120 diagnostic fee for the repair? but I'm sure the bill would have been several hundreds higher.

I have to say, that's a fking joke. Replacing thermostat and housing at the same time as the fuel rails has to be a trivial job.

Hmm, I’m going to speak to my dealers service dept and see what BS they try to feed me.

Note that a thermostat failure doesn't result in loss of coolant, just the engine temperature isn't properly regulated so it either overheats or takes much longer to reach normal termperature,

A coolant leak around the thermostat housing would indicate that either the housing has cracked (and that's NOT a moving part) or the gasket/sealant has failed/wasn't fitted correctly.

I'd monitor it for a few days/weeks to see if it's really losing coolant. Coolant level in the header tank will vary a bit with temperature anyway.
