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.

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.
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.

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.
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

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.
So going with MRC will mean I kill 2 birds with one stone and won't have to worry about the pulley dying any time soon?

I got my pulley from allstars motorsport in Portugal 3 years ago for £350 delivered. I know more recently they had offers of a very similar price. But you can spend more for top end stuff like the Fluidampr which has a viscous damper in it, Dippy has one of these.

I wouldn't advise the bolt over pulleys, like APR as you don't eradicate the potential pulley issue which is the OE pulley is left on and the drive for the SC is bolted over the top. The Aux belt will still run on the OE pulley..
Ignore last reply, only just saw this.

So in layman's terms, I'll still need a new pulley (is this the one you got?) if going stage 2 and wanting to nip this potential issue in the bud for good?

Cool. I've emailed MRC to see if they'll replace it with the one you have when it goes in for stage 2.

My car has APR stage 1+ (ECU/TCU tune and high flow intake). Stock apart from that.

Gotcha, DAVE! haha

I wouldn't assume there's any gains to be had from new pulley and that it's just a preventative maintenance thing, and with that in mind I'd rather do it as cheap as possible (without compromising on quality too much).

I haven't had a recurring box leak. But where is it coming from? Wasn't it the filter housing? How was it fixed? Got any pics?
Took it to an automatic specialist today. They said it's not that bad a leak (any more) and looks like it's coming from the oil pan gasket as there's no sign of leaks any higher up the gearbox. £150 to replace gasket inc. labour. I've asked them to do that plus a full DSG service as they'll be draining the oil anyway (so about £300 all in).

Will report back once done and put a few miles on it.

I did read somewhere that the oil pan can warp over time, causing leaks?

Could we believe that a mechanic who overtightens the filter could also make a mess of torque sequencing the pan bolts?
We could indeed, although I'm using a new company to do this (an automatic & DSG specialist), so fingers crossed they know what they're doing. They have good reviews online so let's see.
