I have no automatic shift issues. Maybe your trans needs a memory re flash. Have the dealer check it out.
My solid roof also pops and creaks.
Paint issues I have one in the Driver side door. Its not really paint however. It appears the driver side door near the top by the door latch had a small ding in the skin before it was painted. It does not appear to have been touched up just painted over. You can't really see it now unless you look at an angle but I do fear the paint might crack later on.
The Chrome wheels look lousy for the money they are charging for them. I see multiple flaws in my wheels no pitting but not a totally smooth job of prepping the wheels before chroming. You can see plenty of casting flaws that were just chromed over.
Your fob issue sounds like that TSB issue for replacing the module. you need to bring it in for that.
The thin paint issue I had the VERY SAME problem back in 1998 with a black C5. I could see the primer bleeding through the paint around the rear wheel lips and also in the coves of the front clip.

Sorry to hear of your problems. My '08 Black A6 has been flawless. In fact I didn't even try the paddles for quite a while because the shift points were so spot on for things like high speed passing on two lane roads and demo runs up straight freeway onramps. The Sport Mode has much firmer shifts, so the wow factor is even greater. The paddle shift throttle blip is a thing to behold. I doubt any human could do it as well. I'd suggest you have your tranny looked at. Good luck to you!

First let me start by saying my 2008 Black Z51 Automatic is my first Vette and I love it. ...
1. The automatic shift points are driving me insane. Heres an example I was at a light with no cars in front of me I started to go on green at a healthy rate of speed. A car coming the oppposite direction turned in front of me. I had plenty of room to just let off the throttle. I lifted and went to throttle up again and the pedal felt dead. I had no power to speak of. Another instance i was rolling at about 30 mph and stood on the pedal car downshifted and took off I let up at around 65mph and the car didnt upshift for what seemed like an eternity as all i heard was my poor LS3 screaming with the rpm's being pegged and no shift following. If this is normal for the automatics I dont know. Yes I know the paddle shift makes it better but that is not the point....

BTW... if you were driving a manual you (the operator) would have to take the appropriate shifting action wouldn't you? Same with the A6, either in S mode using paddles or by controlling the transmission with the throttle.
P.S. - The A6 D mode is an adaptive system. It learns how you drive... so if you want it to act a certain way, drive the way you ant and teach it. Do not blame the transmission. And this comes from someone who drives 6-speed manual Porsches...

[QUOTE=wbear;1562600469]The first tranny prob mentioned is what I call a coast down glitch. I have the same thing on my 07 A6. I think its the way the trans is set up, not a defect. It happens during around town driving at speeds under 20 or 30 mph and so far only in D but I havent tested for it in S yet. It feels like an accelerator pump lag problem on a car with a Carburetor but in our case its not engine related. You let up on the throttle to coast and then when you press on the throttle quickly nothing happens for a second. Its as if tranny is inbetween gears and can't decide whether to downshift or up shift.
If you are granny driving you would never notice it because you don't press on the throttle quick enough demanding snappy acceleration. This condition is not ideal for a performance car but it may be the nature of the beast in D. It dosent happen continually, just under certain parameters. Anyone have it happen in S?
I haven't tried a WOT demand under these conditions so I don't know what would happen.

I only comment about the transmission point. The new A6 is one of the best transmissions I have driven. It can be fully controlled with the throttle. I never experienced what you describe. You must understand how the transmission works and control it. This is without a doubt an operator's issue.
BTW... if you were driving a manual you (the operator) would have to take the appropriate shifting action wouldn't you? Same with the A6, either in S mode using paddles or by controlling the transmission with the throttle.

thats a pretty accurate description of what happened. Not what I am looking for in a performance car

I often tell people to disconnect their battery (overnight at the very least, the more hours disconnected the better) when having issues like this, it's not quite what a reflash with a dealer's Tech II will do but you'd be surprised at how many things can get 'fixed' by doing just that and then letting it all relearn/reset while driving around, especially an issue like this.

[QUOTE=FLHXI06;1562604331]Drive around in S mode and see if it has the lag on coast downs. Let us know if its there too. We might be able to come up with a way to tune the problem out.

I would love to see a video of this, I am still trying to determine if my 07 does this. Is it subtle or obvious if you see it?

This A6s are a little strange until you get some miles on the car and train it how you want to drive it. Mine did some things that I thought were strange too, but turns out that it's just characteristics of the A6 when it's new and doesn't have any memory yet. It definitely takes a while to get used to the 6 speed auto, I had the A4 previously and they are completely different.

One other thing to keep in mind is that t A6 will keep the gear it is in if you lift the gas quickly, I believe it is for tracking the car. Mine has done this many times when I am getting on the freeeway and suddenly let up on the gas. It will stay in 5th or 4th for quite some time because it is expecting me to accelerate hard again (after the turn I guess), not that I accelerate hard getting on the freeway.

The A6 is a very interesting tranny. Here’s the bottom line – never drive it in “D” mode. This is where the “adaptive learning” takes place and, unfortunately, is where most people put the selector when they’re driving “mildly”. The TCM then applies this learned "mild" behavior to ALL modes. That’s the dumb part.
At this point you have several options:
Note: the last one requires re-indexing your windows – not a big deal but you’ll need to do it …
Good Luck and be careful
At this point you have several options:
- Take it out and thrash it in “D” for 1 - 5 shifting several times. It will learn this new behavior and re-program your shift points/pressure. Once it’s running like a “bat out of hell” again (mine does), it’s re-learned how to shift for aggressive driving. Then never, I mean NEVER put the selector in “D” again. Use “S” (sport) for auto shifting and the paddles for aggressive driving (manual shifting). The adaptive learning is only engaged in “D” despite what some people think. BTW - make sure you have plenty of road to run 'er thruogh all the gears at WOT (minus 6th of course) - she's going to be hauling *** when she hits 5th gear!!!
- Take it to a tuner that knows how to shut off the TM (torque management). This is THE most important tune that can be done to a stock C6 with the A6 tranny. Then never, I mean NEVER drive the car with the selector in “D”. Notice there’s a theme here …
- Disconnect the battery overnight than never, I mean NEVER drive the car with the selector in “D”. See …

First let me start by saying my 2008 Black Z51 Automatic is my first Vette and I love it.
With that out of the way here comes the disappointing laundry list.
1. The automatic shift points are driving me insane. Heres an example I was at a light with no cars in front of me I started to go on green at a healthy rate of speed. A car coming the oppposite direction turned in front of me. I had plenty of room to just let off the throttle. I lifted and went to throttle up again and the pedal felt dead. I had no power to speak of. Another instance i was rolling at about 30 mph and stood on the pedal car downshifted and took off I let up at around 65mph and the car didnt upshift for what seemed like an eternity as all i heard was my poor LS3 screaming with the rpm's being pegged and no shift following. If this is normal for the automatics I dont know. Yes I know the paddle shift makes it better but that is not the point.
2. Transparent roof makes noise. Thats nothing new have seen all the posts here on that one.
3. At least 4 paint blemishes. There 4 that I have found where it looks as if there is not enough black paint under the clear coat. When direct bright sunlight hits those spots they are very visible. They are round in size and are about the size of silver dollars. Two are on the passenger side rear quarter panel and 2 on the Driver side rear quarter panel. They are not in the same location from side to side either.
4. Right rear whell chrome is sligtly pitted. Enough said.
5. 50% of the time i press the switch to turn off the ignition the FOB is not recognized. Its in my pocket mere inches from the dash.
Theres my list anybody have any thoughts or similar problems?

Shift/Acceleration lag in 2008 A6 Coupe
I just got my Vette 4 weeks ago and I've just noticed the exact same problem this genetelman is talking about. It started last weekend. It did it again tonight. I was coasting to a red light at about 20 MPH. When the light turned green, I pressed on the accelerator and NOTHING! It seemed like an eternity. In reality the pause is about 1-1.5 seconds before it kicks in and takes off like a bat out of hell. Like I said, this just started happening. Off course, I just hit 1200 miles (the factory recomended break in period) and now I'm laying into the pedal. There is also a noticable but not drastic gap in the tranny linkage between acceleration/deceration. It can be best decribed as a "clink" sound that you can hear and faintly feel. Before I go out and try to "reprogram" or "retrain" this $50,000 car, I'm wondering if I should call the delaer and have them check out my transmission first? I would hate to exacerbate the problem. I'm glad I'm not the only one experiencing problem but disappointed 
that's its happening to begin with. Let me know what you fine folks think.
