Either I need to get used to it or doing it wrong, was doing some spirited driving yesterday and had rpms up high in first gear and when I wnt to hit my + shifter got an X in the heads up so I quickly took my foot of gas to avoid over reving. Why does this do this and does the car prevent over reving.

there is a rev limiter to protect the engine, if you try to downshift and the car is going to fast for that gear you will get the X too...

 

I believe that you get that when traction control is engaged to prevent a loss of control. And maybe the when the stability system is active???

 

if the TC detects slippage it will not upshift.

 

2008 owner's manual, page 2-30.

 

That could happen if you inadvertently squeezed the downshift paddle at the same time as or slightly before thumbing the upshift. Or if you hold the upshift paddle down too long. I don't know if there is a traction-related override, but it could be. You don't mention your speed at the time or whether you were in D or S mode, but it does seem like the car would welcome an upshift. I drive mine in paddle-shift mode all the time and I've never had that happen except in the two circumstances I mentioned.

 

and the 2008 must be in "S" mode to use the paddles.

 

Traction control was probably to blame as I was spinning the tires halfway up the block, lol

 

Press and hold the TC button

 

Paddles DO NOT WORK IN "D" MODE ON TRANS. Work only in "S" mode on transmission.

 

The 2006 has to be in "S" mode also, I think this is true on ALL A6's.

 

I have a 2009 A6 and can only use the paddles in S mode.

I believe the newer models allow paddle use in D and S.

 

Paddles work in D on my 2011...

From the operators manual (9-30) Driving and Operating

"The driver may choose to briefly
activate the Manual Paddle Shift
system while in D (Drive). Tapping
either the upshift or downshift
controls will place the transmission
in Manual Paddle Shift mode. The
driver may then exit Manual Paddle
Shift mode by holding either upshift
control for two seconds. The system
will return to automatic shifting after
10 seconds of cruising at a steady
speed, or when the vehicle comes
to a stop."

 

OP: you have to back off on the throttle a bit before upshifting, otherwise you will hit the rev limiter. On the older models, upshifting at or near red line will get you the X. Try the upshift around 5k or 5500 rpm's.

 

When spinning the tires you have to shift early. I can light-up the tires through every gear but always shift early to avoid the dreaded bog-down.

 

You didn't say what year your car is but mine is an 07 and I was told by the service advisor that this is "normal" and they won't fix it - I have tried shifting ahead of time but it does not work. The only band aid is to quickly shift into D and it will then upshift, try that.

 

Red x had nothing to do with over-revving since the OP was trying to upshift. Also, his rpm's were already up so the red x had nothing to do with lugging.

I have an 07 and same thing, no upshift with wheels spinning. I thought it might have something to do with protecting the transmission but some are saying TC and loss of control? Does anyone know for sure?

If the transmission could be damage by upshifting during wheel spin, could shifting to D cause a problem?

 

2010 and NEWER A6 paddles work in D and S mode.......

 

Need to spend more time with it. I use mine all the time, 76K miles on mile. Love my paddles..... there' a learning curve, but once learned they're great......

 

Ok,

Doesn't seem like some posting are understanding what the OP was saying.

It's not about needing to spend more time w/the paddles. At 152k+ miles on my 07 I've shifted with the paddles for many miles trust me. And some of those miles were aggressive driving. So I know about D vs S. And I understand this transmission limits up and down shifts based on engine rpm...the red x. This is something other than the transmission limiting shifts based on engine rpm. If you use your paddles for mild driving (NO WHEEL SPIN GET IT?) then you won't see the problem the OP posted and won't understand this thread.

BTW, the owner's manual quote by JimTM doesn't address the OP's question, instead talks about engine rpm limiting paddle shifts.

However, this (2007) owners manual statement may apply...

When traction control is turned off, or Competitive mode is active, it is possible to lose traction. If you attempt to shift with the rear wheels spinning with a loss of traction, it is possible to CAUSE DAMAGE TO THE TRANSMISSION. Do not attempt to shift when the rear wheels do not have traction. Damage caused by misuse of the vehicle is not covered.

Does anyone here know about this? I'm sure most know that even with traction control on, it's not only possible but easy to lose traction...you think? Is this why the A6 won't paddle upshift with the wheels spinning? I'm curious because this issue's been mentioned in other threads but nobody posting seems to have a clue.

Can anyone with technical knowledge of the A6 transmission and this issue comment? I'm sure the engineers who built it know, but us consumers with only an owners manual and forum threads? Hit or miss. And I don't remember this restriction with the A4.
