what the hell!!! Hitting brick wall at 80mph

[peiserg]

my OCT milltek cat/exhaust with aquamist rs6 is pretty quick. Pulls hard up to redline in 1st, and 2nd... but now, a new problem.. i hit 82mph-ish in 3rd at WOT, approx 5000 rpm, and the car "sounds" like its still WOT, but is accellerating like not only have I lost both turbos, but 4 cylinders as well... it takes something like 30 seconds to go from 80-90 mph.

Going back to dealership i guess... only thing that's happened.. I was getting a ABS/ETC light, so took it in.. they replaced a "brake sensor," and driving away from the dealership, i noticed this problem... it was constant that day, and is now intermittent.

ideas? no MIL's have been tripped.

Is there any chance that your traction control light is flashing while this is occuring? Do you have VagCom to check for codes?

Transmission slipping?

[Aronis]

Not enough electricity flowing to the Flux Capacitor, so when you hit 80, the time jump does not happen, and you slip past to 82.

Transmission...or torque converter telling the ECU its getting too much torque and its shutting down the turbos...feels like you hit a plateau and nothing is happening. Mine did it at a lower speed in 2 to 3rd gear intermittently. Torque converter was the cause. Only threw a CEL when it finally went.

I sure hope my Torque converter goes before the warranty goes. I'll try to talk them into an upgraded one if I pay the difference.

Good idea,

Talk to these guys http://www.aceconverter.com/index.php they can offer a TC that will hold 800ft/lbs, and have the ability to be locked up in all gears when in tip-mode just need the software modified to activate this which would make it more efficent and also generate less heat.

Did not know there was such a thing for the RS, cool.

What the hell is WOT?

ahh shit i hope it's not the tranny! I thought it might be related to the repair the facility just did on the car...

No TCS light comes on when this occurs..

so why does it pull hard as freight train in 1st/2nd, then stalls out in 3rd? I checked the vag com and no indication that the tranny was having a problem.

gerry

[RS6C5]

Less load in 1st/2nd where as under load in 3rd/4th the problem arises due to the torque generated.

Get vag-com on the car and check the ECU/TCU for the codes.

Try doing a WOT run in 3rd and 4th and see what happens.

I'm sure there are DTC codes. The Torque converter from ACE converters sounds impressive. I know after the DRC has been replaced, this is the last real weak point in a great car.

[Spidercat]

Has anyone done this ACE torque converter upgrade? I wonder how it compares to the offerings from Level10. Level 10 seems about twice as much, but they also offer valve body mods, etc. I think 1 or 2 people on this forum went with Level 10 and were satisfied. Any idea how many man hours to install?

as i stated earlier.. I ran vag com and cam up with no tranny codes. came up with a HVAC flapper valve problem. Is it possible it relates?

at any speed, I printed off my scan, and handed it to the service adviser at audi.

[peiserg]

ok all you precogs with your magic 8 ball predicting my tranny is trashed. the dealer couldn't find any problems, they tightened every fitting they could find, and think they might have knocked something loose when fixing my ABS sensor.

car runs like a raped ape right now..

[RS6C5]

Good to hear!

Let us know the 1/4mile and power it makes on the dyno

[peiserg]

all my dyno sheets are already posted. just search.

fyi.. the problem is back. fawk.
