the v10 s6 project

A6 All/ S6 All
#261

V8A6, of course, you already know all this, but for anyone else who is reading this and might be having similar issues:

Overheating - you may want to look at my new coolant leaks thread for some tips on where to start looking. Other obvious places to start: bad fan, water pump, or thermostat. The latter 2 items are worth replacing if they’re old anyways, especially if you’ve already got the front end off.

Misfires - the usual places to start are (in order of cheapest to most expensive): spark plugs, coil packs, carbon cleaning, fuel injectors.

Ironically seems our cars follow the same plight fix one thing one thing comes back. I haven’t figure out the overheating and it’s interesting in park the car can idle for hours without overheating in drive the car can sit for 5-10 minutes and start overheating, the gremlins are at it again

#263

Ya, fortunately I don’t have any real major issues going on anymore at the moment, but since my radiator got fixed the other day, now I get a sporadic “Hood open” warning on my dash. Like, off and on 1000x during a drive. Pretty sure the idiots at my local shop put my front end back on wrong. There’s no way I’m taking it back to them to fix though, every time I have them fix something they break something else. Every time. Also just got a tire pressure light this morning that I need to look into, and my airbag light is still on. Would be nice to start my car one day and not have any warning lights.

That dash!! I need that dash!! So nice!!

#265

Thanks man

So, they pulled the thermostat, that was just installed along with a new water pump, probably 1000 miles ago, and found it was not opening. Replaced with a new one, and no more overheating issues!

Now, we are back to troubleshooting the misfires. Will update again when we have some progress

#266

Sweet, one of my things to check was the one! I’ll pretend like I helped :wink:

Good luck with the misfires!

Wow that dash is sexy - looks like my first mod will be some interior color changing :slight_smile:

#268

well, we pulled the intake manifold again, and all looked pretty good. Unfortunately, when the split the clamshell the lower half got damaged.

Luckily, I have another one, so they are piecing the the best from both together, and should be back in action fairly soon.

In the meantime, ordered…

JHM Intake spacers
JHM lightweight crank pulley
JHM SAI blockoff plates

The only thing I havent added is the JHM lightweight rotors. I am a HUGE fan of lightweight wheels and rotors. The thing is, I have the RS6 calipers waiting on standby. So, if anything Ill have a custom set made for them, after all the rest of this shit is sorted out.

So, at this point I officially have the most decked out v10 S6 that doesnt run… LOL.

That said, there are only so many parts left on the car that have yet to be replaced with new. Where logical troubleshooting fails to determine root cause, throwing money at a bunch of new replacement parts will eventually resolve the issue. That is the plan, anyway.

Fingers crossed!!!

I love the piano black surround! did you respray yours or get one off an Rs6? I hace been trying to find an RS6 RHD one but they are like gold dust. i might just by a a6 one and get it sprayed piano black!

#270

OR why not just wrap it with high quality gloss black vinyl? I might take a stab at it; I really dislike the silver as well.

#271

Thats a good idea batman!

#272

I got the dash surround from German ebay. It was from an RS6. It really should have come standard on the S6.

#273

I agree. The silver really cheapens up the overall look IMO. It should be pretty painless to wrap as long as you have a heatgun to push the wrap through the openings and get smooth.

It’s been a few years since I’ve carbon wrapped anything, but the 2x2 weave is SO much easier to work with than a twill pattern (although a twill arguably is more interesting to look at), it just doesn’t like to wrap around stuff very well with a vacuum bag. On this part, it would definitely pull the weave out of alignment here and there - it would probably trigger some OCD on my part if it did. 2x2 is a lot easier to control…

We’ll see how motivated I get. Epoxy isn’t the easiest thing to work with when the temps are lower, but it’s a decent winter project idea. :slight_smile:

Here’s a couple parts I’ve done

Just bought one today on ebay. They’re out there but generally I think you have to find them in Europe and have them shipped over.

#275

Them pics dont work for me unless i open them in a new tab.

#276

ug. No biggie, I can’t figure out how to make em work I guess. still need moar gudpoast before I can has edit.

#277

Any updates? hope everything is going well…

#278

Actually, there is an update. My winter beater blew up, so I swapped it with the S6 at the shop.

We have eliminated the misfires through some troubleshooting, but still havent determined root cause.

The good news is, I am ripping around, having fun, and gathering logs. Hoping to have everything sorted in the not too distant future.

In the meantime, my impressions…

The v10 S6 can be setup to handle amazingly well, resulting in a car that feels WAY smaller than its size. I am sure everyone has their own preferences, but Ill outline mine:

  • H&R rear sway bar (rear only!)
  • Coilovers (I have H&R, but KW would also be nice)
  • Lightweight wheels (just switched to 19 OZ Legerras for the winter setup) Try and keep the wheels 25 pounds or less
  • ESP off = steer the car with the torque of the v10
  • Lightweight rotors (OK, havent got these myself, but anything you can do to make the wheels/rotors lighter is a huge gain in stopping, accelerating, and letting the suspension do its job!)

The one thing that I am really hating, is the overboosted, light as a feather, steering feel. Apparently, in Europe they sell the car without servotronic. In North America, it doesnt seem so.

A3s have a setting in the ECU that can be adjusted with VCDS on group 44. A6 4F, apparently does not (I tried)

Next step is to try and install a resistor on the servotronic circuit. I have ordered the top of the line 4 ohm resistors, straight from China! So, Ill let you know how this experiment turns out.

The new wheels dont look as good as the old, but minimal rubbing with the new offset, and the car is handling incredibly well, even on winter tires!!!

265/35/19 Winter tires
19x9 et42 OZ Legerras

For some reason, with the new wheels, the car really needs the RS6 side skirts

Wait. Did I miss a write up on the exceedingly rare long tube headers?

#280

Looking good v8a6. I think the wheels look pretty good! Glad to hear you have the handling dialed in even on winter tires. Would love to ride along in one with coils and sways.

Assume handling in he snow is also still pretty good, with winters and the RSB? No oversteer situations with the RSB, how much different is the rear sway from stock?
