With S4s, the final B8.5 facelift supercharged cars were registered in 2015, mostly on 15 plates

B9 turbocharged deliveries started at the tail end of 2016, so 66 plate.

I don't think you'll find a 16 plate S4!

The S5 changeover to B9 was later...
Ok, that makes sense. Mine is a 15 plate and was ordered days before they closed the books on them.

Quiet in here wavey

Anyway, I'm always on the lookout for a new B8, and saw this on ebay. Personally I think the price is somewhat toppy (otherwise I'd have been interested), but was surprised to see a 2012 62 plate manual. I thought the facelift (s-tronic only) had come out in 2011 (or early 2012)?

And also noticed this is still for sale, been on for ages. Anyone been to look at it?

Morning all,

Would appreciate some advice. We're due the 'big' service on the fast bus, including the DSG oil change etc. and I'm considering making a couple of tweaks - thicker anti-roll bar on the rear, maybe a Revo tune for engine and gearbox and Revo's airbox too.

The reason? We're off for a family holiday up in the wilds of Scotland and my wife and I will indulge in some driving fun whilst there and fancy letting the beast breathe a little better.

Has anyone done a 'mild' set of tweakage? If so - worth it? Would you add an exhaust? Are there better mild improvements to consider? Anything transformational?

All answers appreciated - even those who advise against doing the above.

Cheers.

Here's the new reg number. https://cazana.com/uk/car/EO62OBN
62 plate is definitely quite late for a pre-facelift car, so possibly one that was in stock at a dealership (or in a field!) for a while before registration? Facelift was announced in late 2011...

It was built on the 9th November 2011. That sat around somewhere for a looooooong time!

I have a manual b8 S4, my friend has a DSG model with a proper remap (Revo or such £1k+), he actually lives abroad but one day he brought it over and we had a quick dual. His was probably making 410-420bhp, but oddly there really wasn't alot in it, he just seemed to pull a couple of car lengths at each gear change.

I actually drove it round the Nurburgring but it was a while ago and before I had my S4 so cannot recall if it felt much faster, I do recall driving a B8 RS4 at Spa that same weekend (it was a good couple of days!) and I dont recall it feeling much faster than my mates mapped S4, different power delivery of course.

I'm not sure how much the map is worth it, especially as the brakes on S4's are pretty prone to warping (IMO - even with genuine discs and pads). His friend had a GT3 911 though and his S4 could easily keep pace in a straight line. However if you want a big more poke and have the funds then I'm sure there must be a difference with an extra 60-70bhp....

Sorry that post is probably not very helpful!

The B9 S4 wasn't out very long at all before the B9 S5 was (if at all). Both were back end of 2016 but with most cars coming through early 2017.

But I think the B8.5 S5 was made later so there was pretty much a straight transition from B8.5 to B9

Does anybody here have any use for an iPod connection cable for the S4?

https://www.amazon.co.uk/Adapter-Connect-Generatio...

I have one and I was going to stick it on eBay, but it's only worth a few quid. I thought I'd see if anybody here can make use of it. Cover the postage and it's yours...

32K miles in, I'm getting a bit of a grumbling/vibration through the brake pedal: Pads all look OK, so front discs seem the likely suspect.

I've measured about 0.7mm of wear on the disc face (vernier stuck through the spokes, comparing worn disc face to the unworn section), but am curious about what the "allowed" wear is. No obvious cracks/grooves...

Are they still the original pads? if so at 32k they must be about done, mine needed replacing around 25k but the discs are still fine - 0.7mm of 'lip' isn't much.

I posted the below back in December on a similar subject:

[quote] If it's had pads before then bank on discs too. Our front discs were worn out after x2 sets of pads at around 50k miles. The minimum thicknesses for discs are 28mm front (new discs either 29.5mm or 30mm depending on age, rears minimum 20mm and new are 22mm.
Hope that helps smile

It does - It had front pads at about 18K and I politely declined the suggested new discs at that point smile I was hoping the front discs would last to about 40K, but maybe not smile

Looking like being an expensive year just on routine maintenance - 4 new tyres, discs/pads all round, MOT, Inspection service and DSG oil change all over the next (and last) few months...

I feel your pain! Our last service was quite 'chunky' as it was discs and pads all round, new s/c belt and aux belt, plus the usual service items and brake fluid. Brake parts are actually not too horrific - I went for Brembo all round and cost was under £250 delivered via carparts4less.co.uk with a promo code. Happy with their performance so far

Second box service on ours can probably wait another year, at the current mileage rate....

Ah, the joys of running a fast Audi.

All the 'big' service items came up at the same time, so thought to do some preventative maintenance with our local indy VAG expert at the same time. So - full big service (plugs, filters etc.; gearbox oil) and threw in the s/c belt and a brake bleed/fluid change at the same time.

Whilst it was in, the man discovered a leaky rear left side shock, so sent it back in two days later for a couple of new OEM items across the rear axle.

I am now somewhat poorer and have just the one remaining kidney - but the upside is that the fast bus is running very nicely indeed.

About to embark on a 10 day jaunt to the Isle of Skye and back - will endeavour to capture some photos.

Id be interested in your photos and also your thoughts on Skye smile

New front discs and pads needed to sort the grumbling from the brakes, which had turned into a obvious and very nasty vibration over the course of a month or so.

I'd taken the wheels off and checked pads and disc thickness which were all OK. Booked in to to dealers, and dial test indicator showed that the discs had "warped" (or started wearing unevenly somehow). New discs and pads and all is good again, but I'm unimpressed that discs basically failed after only 33K miles. No hope of warranty replacement, it seems.

Anyone else had this? My E28 Beemer used to demolish front discs, but I've never had another car with an appetite for them!

General consensus is that OEM isn’t brilliant for wearing brake parts in terms of resistance to corrosion. In particular......

Haven't got a S4, but have a car with the S4 supercharged lump. At 82k miles now, do I need to change the supercharger belt? Also, is that the same belt driving the ancillaries e.g. AC? And when the belt is changed, is it best to do the pulley as well?

I think they're replacement is recommended at around 60K. Possibly S/C oil change due soon too, but I don't think pulleys are routinely replaced?

Looks like it goes from crank to S/C via tensioner and idler, but ancillaries are driven off a separate belt.

From memory the pre-facelift (in the B8 platform) didn't have an S/C belt change listed in the service schedule, but silentbrown is correct that circa 60k is the recommended interval. The belt only drives the S/C and isn't expensive. The aux drive belt for all the accessories needs to come off to access the S/C belt so it makes no sense not to change at the same time. Pulleys on mine were left as-is.

S/C oil change isn't listed to a schedule, but I do recall reading a suggestion that around the 100k mark makes sense. HOWEVER, to change it I believe the S/C needs removing from the engine, as access to change the oil involves turning the S/C upside down......
