I have an '05 automatic I purchaed used with 9000 miles. I'm not complaining, but from a dead stop on warm F1 tires, the tires will spin maybe one revolution before gripping (no squeal at all). The car gets up and goes from there, no problem, but I was wondering if all automatics perform the same?
I'm not in the habbit of dumping the gas peddle at a stop light, but it seems to me it is a good indication of torque delivery, and fundamental drive train health.
I'm taking it in for an allingment next week so I thought I would ask the forum to make sure I shouldn't have them look at something else. It has 20K miles now, and I treat it very fairly (no track time yet), but who knows what happened in the first 9000?

 

I can't speak for the A4 transmission, I have the A6 in the '06. I have the F1 supercar EMT tires on the Z51 and that is something a lot of people complain about, all the F1 EMT's. Cold and wet weather traction is a source of the most complaints. I have found that the sound depends on the pavement you are on if the wheels spin. Sometimes a small chirp and other times no sound. As far as hooking up, they seem to do fine in they are very warm. Also, if you have the steering wheel turned at all, they will spin period. That's what a lot or torque is going to do. If you plan on tracking the car a lot, then do what many others have done and change the tires to a good non run flat. Do a search and you will find many discussions on tires. For me, it's my daily driver so I don't plan on running anything except the run flats. I also don't track the car but get a little spirited every now and then.
By the way, welcome to the forum and don't forget the wave!

 

I think this is kinda a good thing. I have the A6 Z51 with the F1 super tires. i think the A6 is geared (1st gear) a little different than the A4?? I have a 79 C3 that dynoed at 406 RWHP. Quite a bit more than my stock C6. It is a modified 383 .40 over 386 storker, AFR alum heads, 750 holley double pump victor intake, true roller, 280/520 cam etc . Well I can flat out roast the 275/60/15 BF goodrich tires. The car is front heavy - rear light. The C6 has a very good F/R weight ratio. You got "sticky" tires and 10" of them on the road. The rear transaxle gives good bite, but less wheel spin. My C3 is about 50+ hp more than the C6, but while it's doing a great "burnout" the C6 is launching much more effiently. It also goes about 600 lbs less. So the C6 beats it in the quarter (not by much though) And the extra 15 MPG aint bad either. Bottom line. Take a better launch over the show off burnouts. At the price of these tires, it's a blessing in disquise. A new 911 Porche Carrara beats the ZO6 0-30, better launch - rear engine. Than the torque and HP of the Zo6 takes over and it's bye'bye time for the Porsche Bottom line, The car is fine IMO, take the launch over the wheel spin

 

Let me be more specific so this thread doesn't go out of contol with tire choice discussions.
Does your C6 A4 spin the tires (more than a single turn) on a straight full throttle start from a dead stop? Mine won't, do I have a problem?
Don't misunderstand, I appeciate your insights on Tires and power delivery, and I agree I would rather have grip then slip. The question is more aimed at is my car delivering normal power. I just want to be normal

 

Doesn't sound to me like you've got a problem. I used to have to make a left turn into fast moving traffic in the Cool Springs area of Franklin TN when leaving the rehab place where my mother was staying. My 05 A4 silver coupe would spin the tires no more than that back in the warm days of late April. I wasn't giving it all the gas I could, but I was getting on it quite a bit.

 

I DON'T think you have a problem. My C6 is the same as you describe. I was just explaining what is attributing to it. I think your A4 is performing OK

 

Not from experence here, but does anyone think that would be Traction Control doing it's job ?

Makes sense to me.

 

Same for my 05 A4 F55. Sounds like a normal, fully performing auto C6. I'm ok with the grip vs slip anyhow. Try the same test with traction off.

 

My a4 will do that too. The traction control takes over as soon as the tires spin ,but they will allways spin a little first.

 

My A4 is like that too. You can spin a lot with traction control off but beware it can really get out from under you with everything off esp if aimed anything other than straight.

 

This forum is the best!

 

IMHO... You have to disengage the TC to competitive mode.. you also gotta be in 1st gear (A4 Auto)..just leaving it in 3rd will cause an over rev with the TC on and if you get ever so squirrly, it will shut down, to keep you from drifting around.. I have tested this a bunch and the only way I can get a great starting burn is the aformentiond...However, when going like 30 mph in 3rd and slamming it, the beast hops up like a cartoon car and just flat out chrips.. when doing this I leave the TC on.. just so I dont friggin loose it. Again IMHO...

Edit.. my ride.. 2005, DSOM, Nav, A4, F55, Z51 Mod, KN intakes, stock 3:15 rear and more car than I dreamed...

I have only had this C-6 A4, F55 a couple weeks.. mind you, I love the car, but I couldnt figure out why I could not just light em up like my 66 Corvette or even my 67 Chevell SS.. It just seemed like a throttle limiter or something was a miss, so I decided to look it up.. I didnt even know this existed.. after I did it, man...l mean this sucker smoked em...

From the owners manual...

First this...

TRACTION SYSTEM AND ACTIVE
HANDLING – OFF: By pressing the Active Handling
System console button for five seconds, the driver can
turn the Traction Control and Active Handling Systems
off. The message TRACTION SYSTEM AND ACTIVE
HANDLING – OFF will be displayed in the DIC, the
instrument panel cluster light will be on and a chime will
sound. You can acknowledge this message by
pressing the RESET button. The anti-lock brake systems
remains on with the Traction Control and Active
Handling Systems off.

Then....
Active Handling System
The Active Handling System is a computer controlled
system that helps the driver maintain directional control
of the vehicle in difficult driving conditions. This is
accomplished by selectively applying any one of the
vehicle’s brakes.

So then this...

Competitive Driving Mode
The driver can select this optional handling mode by
pressing the ACTIVE HANDLING button on the console
two times within a five second time period. A chime
will sound and COMPETITIVE DRIVING MODE will be
displayed in the DIC. Competitive Driving Mode
allows the driver to have full control of the rear wheels
while the Active Handling System helps steer the
vehicle by selective brake application. The instrument
cluster light will not be on. The Traction Control System
will not be operating.

So I held the button down for 5 seconds, rather than just pressing it for a sec...

THE DIFFERENCE WAS SO POWERFUL TO THE REAR WHEEELS.. WOW.

 

Sounds like it to me.
