My 2015 S4 with the later CREC 3litre V6 does low 30's on a run (around the 80mph mark) and low to middle 20 around town, of course that's subject to how I drive it!
That's with a stage 1 tune and induction mods.
I bought it on Ebay, was recommended by someone on the Quattro Owners Club Facebook page, sold by carbitsrus15. It's a genuine Audi cover for a B9 S4 but fits the B8.5 S4 perfectly, £69.00 inc free postage.
I just had a look on their items for sale and they're not listing any covers now.
Do you have the service book with the car, the one that would be stamped by the servicing agent when a service has been completed?
I ask as the VAG group as a whole stopped supplying them with new cars some time ago, however they can be bought through them or on flea-bay.
I have used a battery conditioner/charger/trickle charger that I bought from Aldi for many years, used on my (then) service barge with a standard battery, rally cars with dry cell batteries and my Maserati Gransport which was a garage queen and only came out in the summer months.
I fitted an eBay set of LED's when I bought my 2015 plate S4 last year (Sept 19).
I have noticed a couple of them have started to fail now, sun visor, glove box and most importantly the boot.
I think the eBay kits are a bit hit and miss tbh, I fitted a full set to my brand new Octavia VRS (also...
Or put a switched 12 volt live to them from a battery, stand back and flick the switch, Boom Boom!
Sorry that's very immature, I saw it carried out as a demonstration on a Fire Service RTC Extrication course.
As far as I'm aware no.
You have to change the whole front end to the later B8.5 spec, bumper, grill, headlights, bonnet, obviously the fogs and surrounds, and I think the wings also.
Use the search function as there's a couple of guys that have done it, I know one is "My S4 project" in the B8...
That's a very linear power curve making more power throughout the rev range, torque curve is almost identical to stock. just a lot more torques at the same point (to quote Jeremy Clarkson) .
Many years ago I owned D plate Coupe Quattro (oh how I wish I still had it as they're worth a lot of money now) and the only time that crabbed was when I locked the diffs, so when I bought my S4 I was thinking the same as you I.E have I bought a lemon and the transmission is ******.
you don't say if it's a Quattro or not, if it is then the noises from the front end are quite normal as Spartacus68 said above.
I own a 2015 S4 with only 24k miles which does it, it's perfectly normal and nothing to worry about.
I own a 2015 S4 with the CREC engine, it's also just had an APR stage 1 map.
I've not had any experience of either the Golf or S3, but I like you went for the looks of the facelift B8.5, the engine came second, however now I have one I've come to love the engine and even more so since it's been...
I also use the standard jacking points, which in your picture are the silver sections behind the front wheels and in front of the rear wheels.
You can buy Audi TT puck type jacking point pads on eBay which saves damaging the sills when you lower the car onto the stands...
