good evening ladies and gents,

Just about to commit to buying an S5 V6t on just over 80000. Got a good deal on it. Just wondering how reliable these engines are.

Hi mate. Welcome to the forum. Do you know what is the spec of the car, manual v auto and at what price you are getting it at? Stealership, dodgy 'performance car specialist' or or private seller. A bit of more info would help.

Having said that, a lot of useful info in the below thread. Pay attention to @Dippy , @arad85 @scotty76 @jdp1962 and few others' comments.

Sorry, yea it’s a 2010, 85000miles - s-tronic gearbox was replaced by Audi at 68000 (spoke to them, it was done under warranty as a good will gesture). Has good spec with full Audi service History up to 70000. I’m getting a 1 year RAC warranty with unlimited claims up to £3000 a time. They are giving me good money for my trade in. It was serviced at 76000 by a VW specialist who I’ve also spoke to and has told me they gave it a full service. There seems to be no issues with it and they are servicing it, mopping it and sorting a few paint chips for me so will be mint. Any advice appreciated. Full price they are asking for 13000

@Tom Ashby , welcome to the House of Fun, Tom. :)

Sounds like you're getting a tasty motor, there. Let's have some pictures as soon as it's yours.

Hi jdp, thanks for welcome!! Always wanted one of these, it’s ibis white with the Le Mans 20” alloys. Will get picks up soon. New to Audi, have modified others, STI/ST Etc. Does the price sound ok ?

From my research the 3L supercharged from Audi is one of the most bulletproof engines. Its other areas like the transmission where most issues are seen

Seems fair price mate. Like @metzer_001 has mentioned mechatronics in the B8 was an issue and mid 2014 onwards it appears is a safe option. Yours is replaced so should be good. Oil consumption on earlier engines including a few B8.5s was also reported and is usually fixed by replacing the PCV valve.

Forgot to mention waterpump and thermostat but then some B8.5s have reported this issue as well.

Thanks gents, the way I see it, the gearbox has been replaced so shouldn’t see a failure on that. Most other items that could potentially go wrong should fall within my waranty cover so I should be good.

What about timing chain issues ? Is this a potential major issue?

It is or can be however, it appears you are going for warranty, which I believe would cover it.

Quite a few videos on YouTube on possible symptoms and fixes including cost to replace.

Thanks Tashfeen, I’ll have a look, I’ve heard it’s a prolonged rattling after start up

Well as many on here know I have a cynical tendency so I'd like to know what gearbox version the replacement was! If you can get a VCDS scan it would be great.

Waterpump, 'stat and PCV have been mentioned. Timing chains are an issue but don't worry about that until you get that cold rattling - there are plenty of audio clips on the web you can use for comparison. But I have yet to read about actual chain slip (other than one case which seems to have been due to the tech ****ing up the chain fix) so you might even be able to live with the rattle if its not too bad.

The part that hasn't been mentioned yet is the crank pulley. Enough have failed to know its a potential problem, but not enough to get a good picture of when it might fail. But I have read reports of failure at less than 85K. It's a 2-part pulley glued to a polymer damper. This polymer degrades over time. If the belts don't run true then you risk bearing wear - the most expensive being the charger, but it can fail completely - and obviously a lump of spinning metal at the front of the engine can cause collateral damage, e.g. to the rad. As a minimum shine a strong light down to the pulley with the engine idling and check for any signs of 'wobble'. But really it has to be considered a service item and at 85K I'd consider getting it replaced along with the belts. Of course there are plenty of larger ones it can be replaced with but that's a subject for those without warranty...

EDIT: What are the terms of the warranty? They are never fully comprehensive are they? The problem with the darn OE crank pulley is that the failure mode is clearly 'wear and tear'!

Hi Dippy, thanks for the info. So I haven’t mentioned yet that the last 8000 or so miles the car was owned by a gentleman on here. In that time he has posted that it was taken from his drive but was only driven 15 miles which he varifies by the distance from where it was taken and the petrol used. This car is not logged anywhere (hpi etc.) as stolen I suppose because he got it back relatively straight away with no damage etc. He also says he had the crankshaft pulley issue, this seems to have resulted in the belts snapping. He posted that he replaced these.
I used this info to broker the years warranty, top dollar on my trade in and several items done to the car before I buy from the stealer.. sorry dealer. Now before he owned it 8000 odd miles ago it was full Audi servicing + the new gearbox by Audi (need to check which one, cheers Dippy). I suppose there are two ways of looking at this info, but at least I know it’s history right ?

As long as the required work is carried out and you have receipts as an evidence you should be good to go mate. Keep the chain rattle in mind, you can also call Audi to confirm the mech unit fitted to the car in case you don't have VCDS.

Pick up the car, go straight Stage 2 and never look back

Ha ha that’s the plan !!

Haven’t got any receipts for the pulleys and belts unfortunately just this guy CharlieSaudi saying he’s changed them. I was thinking of direct messaging him and asking him what he’s carried out, can’t find how to DM on this site though.

I have spoke to all the Audi garages that have worked on the car and it’s definitely had a new gearbox at 67000, just need to confirm which. This was done in 2015.

Out of interest, how much is it to replace the belts and pulleys? And by them actually snapping and goin into limp mode, could this cause many other issues? Dippy mentioned bearings.

If the charger pulley snaps then the car will still run but with reduce power. If the aux pulley snaps then without the alternator charging the battery the engine will have a reduced running time, without the coolant pump turning the engine will start to overheat, and off course there's the loss of power steering and AC. I'm not sure if it will actually cause limp mode...

Thanks, I’ll check for excessive play in the pulleys.
I’d like to contact the guy off here that owned the car @CharlieSAudi, he may have left now he has sold his Audi.

Will do, enjoying @lincoln_dj posts and @Dippy. Going to go for the intake first. Already have the silicone intake hose on but don’t pick up the car until Monday and haven’t investigated what’s inside the air box yet.

You’re lucky, I bought my car 13th August and haven’t driven it yet.

Straight to the retrofitters for extensive upgrades.

Has it cost you more than the purchase price in upgrades yet? ;)

No, but not far off.

Probably about £4K so far with about £500 left to go.

Not including non oem mod costs which are separate!

FYI my options were £6610 which was all available except TV, towbar and the purely aesthetic ones.

There's no way you have a CREC-engined S5 for £5ish K... Or are you referring to OEM + non OEM when you said not far off...
 

Adamantium

Registered User
When I said no but not far off, I was joking.

The pricing was what I’ve actually spent on retrofits so far and includes changing the seats for two tone.

I paid 23k for the car. I’ve also spent about £2000 on performance mods that I’m yet to fit (throttle body, fluidampr and pulley, forge radiator and I suppose you can count the fis control in there too).

23k for a 2015 doesn't sound too bad TBH...
 

Dippy

Indeed - my 2015 S5 cost me £43K!

43 with all those options and no miles!

I’ll be in for 29 with 32k miles on it and three years old!

Just realised you bought my car! Glad someone on here got it.

Really didn't want to sell had so many plans but house deposit was required:(

Inside the airbox is a K&N air filter, if I was you remove the box get yourself some jubilee clips and a breather filter and fit straight to the filter the whine is amazing!

There's a quantum remap on there pushing about 400bhp didn't want to much and both resonators removed, its making me sad now thinking about it lol.

Lol that explains a lot!!

Thanks, I noticed you posted worries of engine noise, anything come of that? I have just gave the car back to the dealer due to a knocking coming when you change direction, he thinks it’s due to bushes or anti-roll bar. Was the gear box mapped.

Thanks for your input I appreciate it.

Yeah the engine noise was just me being me lol apparently it's normal being of the high pressure fuel injectors so nothing to worry about there.
Oh really I didn't have any issues with that, hopefully just something simple for you mate.

Nothing done with gearbox I wanted to see how just the mapped felt first but was definitely on the list to do.

Hope your enjoying it as much as I did.

Yea love it, wanted one for ages. Sounds epic when you open it up.

Sorry for all the questions, how about the pulleys, I see your post about changing them, has this been done as I know it’s a common thing along with the thermostat issue.

Spoke to AUDI and the Gearbox replacement version was 0B5.

They will not give me proof or receipt of works due to the previous owners details being on the paperwork.
 

Dippy

Registered User
Yes it would be 0B5, they all are. There are 3 major revisions of 0B5. If you ever have a chance to hook up VCDS and take a scan it might show which one you got.
 

Tom Ashby

Registered User
Got this response from AUDI...

I have spoken to the workshop controller & according to the records you have the latest gearbox we would now order. So that would make it the last revision. I can supply you with the part number if that helps - 0B530070580N001
