Hi guys,

New to this forum and new to Audi ownership. Just picked up a 2012 S5 sportback with 99K miles. Seems very tight and a great drive.

Other than the DSG service is there anything else that I should think about doing to avoid future problems considering it’s done 100KHeard supercharger pulley should be replaced at 120K for example.

Searched but didn’t find much.

Thanks in advance.

hopefully others with the same car (I've got a 2008 V8, not the V6) will chime in, but looking further, you have a timing chain, which I believe is there for 'live' in the car and doesn't need changing unless it's showing issues (ie, rattling).
So you might be safe without having to do that.

Here is something that I just found that is interesting from Audi.

Model-Year-2012-English.pdf (audi.ca)

It shows what is a minor and major service, so you can check against your service records to see what has and has not been done. I would assume that if your car was taken to audi for it's regular service intervals, all the stuff in this pdf would have been done, but you can always ring them to check.

Timing chain will be expensive and it is not urgent - just noisy - so leave it until needed.
Supercharger and aux belt should be done every 60K IIRC.
Not everyone gets pulley failure - I have heard of cars into the 100Ks on the original but I also heard of one failing at less than 30K.
Based on its infamy, the DSG should get the TLC. Consider getting the gear oil done as well as the ATF, and for the latter remove the sump and replace the internal filter.

Thanks for this. Had some sh**t news today. Took it for an oil change and they found a big oil leak coming from gearbox.

Anybody have any recommendations for Audi S-tronic specialists South East?

Only had the car a week and I'm sure the guy I purchased from knew about this as it had a DSG service recently. I might have to threaten legal action if it's a costly fix.

Hey Man,

How is the situation on the oil leak?

I am planning to buy a 2012 S5, but kinda afraid I just burn my money, going through the forums, 71K miles on it, so might be good for a while, and I don't mind spending on maintenance, but problems with the gearbox sounds like a nightmare.

And DJ mate, if the seller was a private fellow then I am not sure what you can do. A dealer must give a warranty but not a private as far as I know. So even if he knew as sounds likely than you would have to try a solicitors letter and then the small claims court I guess.

Attached is a service interval list. It for MY 2014, but it should be mostly applicable to yours too.

It's the crank pulley that can fail. Not the actual supercharger pulley. As Dippy says, they can fail anytime, but usually give a knocking or rattle sound, sometimes a creaking as the 'rubber' insert part fails.

Most upgrade to a performance 'solid' pulley so this doesn't happen and you get more power. :)

A big oil leak!? Depends where it's coming from? Could be the garage that did the service didn't tighten something? Oil leaks are normally minor issues with seals/gaskets. It's abnormal noises and dahs warning lights that you have to be concerned about. If it was a big oil leak, you would see oil on the floor where you park you car?

Should have got some pics whilst it was up in the air. Never really trust a garage that says your car has a 'big oil leak'. You should get more info and where it is actually coming from and possible causes/fixes from the garage.

Not sure if you will find a manual B8.5 S5 in the UK, never seen one, not sure if Audi did the manual in B8.5?

Audi stopped producing manual gearbox cars in ROW (as opposed to NA) from 2012 facelift.

Also Dave is correct "big oil leak" does not necessarily equal disaster. You need details.

I thought so, just wasn't sure!

Turned out to be the DSG oil filter housing had cracked/o-ring damaged. Must have been over-tightened on last DSG service they recon. Very cheap fix luckily - drives spot on ever since.

Thanks for the info! Have you had the crank pulley replaced? If so, how much was it including labour?

I'm thinking of going MRC stage 2 in a few months. Assume that would be the time to replace the crank pulley as they'll be doing the supercharger pulley at the same time?

Cheers

As I said :D Glad it wasn't anything more.

A cheap fix to 'reseal', but depends on much oil you lost @£20 per litre?

I replaced mine with a CTS 187mm pulley way before my crank pulley was worn. I changed my pulley at 40k miles and it still looked like new, so I sold it to someone with a split pulley. :)

As you will see, I'm the king of DIYs on here and do most of the maintenance and upgrades myself, so can't comment on labour costs.

MRC are well recommended and will quote you inclusive of fitting the pulley for stage 2!

You don't normally change the supercharger pulley due to the crank sizes available now. It used to be the big pub chat to say, 'I'm dual pulley', but with loads of options and sizes for the crank, the SC pulley isn't touched or needed.
