Sometimes (but only SOMETIMES) I can not get my competition mode to work, or the active handling to turn off. However, sometimes the active handling will turn off and everything seems normal.

I follow the directions in the owners manual...but sometimes all I can get to turn off is the traction control.

I never have a problem turning off the traction control.


Has anyone else had this problem? And, what was the solution? Car has less than 8k miles on it……2006 A6.

Thanks.

 

Are your tire pressure sensors working? If they are not you can't select comp mode. For example when I run my drag slicks after about an hour of driving without shutting the car off I get the service tire pressure sensors message and I can't select any mode except traction control off.

 

A way around this is to simply press "ON" (no clutch). Let the DIC display the word "Corvette" and press "OFF". Now start the car.

Voila! Now you can access all AH/TC and Comp mode settings without TPMS.

 

Wow! Will have to try that!

 

Whoa! This is news to me too! Thanks for the hot tip.

 

I learned this from a forum member many months ago. Have since been doing it and it's worked everytime. Enjoy!

 

Damn just when you think you know everything about your car...

To the OP, is it possible you're just not consistent with your timing of the button press procedure, since it's not just on/off? I can't understand why it would work sometimes but not others without a common variable being made aware to you. ie; at a certain rpm, mph, gear, tire pressure, etc.

 

ok hows it work on an automatic?

 

Funny you say that Dennis. Was thinking that when I posted last.

Do you have to apply the brake for the engine to start? If so, then try not depressing the brake and just push the button. I know this is the case for many push button start cars these days. No brake with a quick push should put the car in a full "ON" state without the motor firing is my guess.

LMK, interested to hear.

 

i dont rememberi think i just hit start, i have to hit the brake to unlock the shifter

 

Well......I couldn't get it to work on my 2006 or 2009!!!

I tried several different scenarios and couldn't get this procedure to help.

I have a spare sensor (not mounted in a wheel) and programmed it into the TPMS, then after that one sensor was programmed I turned off the ignition. The DIC displayed "0 psi" for the left front (the sensor that was programmed), and "xx psi" for the other 3 wheels.

In the above scenario, as soon as I started the car I got the tire/exclamation point light and a message of a flat tire in the left front. I could turn off the TC, but could not go into Comp mode or turn AH off completely.

I shut down the car, then tried the technique LEAVINU described, but still could only turn off TC but nothing else.

I parked both C6s next to each other and programmed them with each other's sensors. I didn't drive the 2006, but it indicated the exact same thing on the instrument cluster and DIC as the 2009. I've tried several scenarios in it when people have come up with "solutions" for running without sensors, so I know what the car will do - and there is no way to defeat the TPMS.

When I started up the '09 and went for a drive, I was able to go into Comp and turn off AH. The DIC displayed the pressures of the tires on the other car - just like if you swapped to track wheels/tires your car will display the pressures of the tires in your garage. The TPMS memory will retain and display the last known pressures it received from the sensors that are programmed into it. If it doesn't receive any update signals because the tires are in the garage and not on the car, you'll have a period of time (see below) before you have a problem.

Then I stopped and disconnected the battery. That will drop the last known pressures of your tires with the sensors that are programmed into the TPMS. After doing that, I started up the car and began driving again, and I immediately got the tire/exclamation point icon on the instrument cluster, and I was unable to go into Comp or turn off AH. I tried LEAVINU's technique, but it didn't do any good - still couldn't go into Comp or turn off AH.

I stopped and shut down the car and tried LEAVINU's technique - didn't work!! I was unable to turn off AH or go into Comp mode.

LEAVINU, I assume you are driving without any sensors. If so, what is displayed for tire pressures in your DIC? If you have any pressures displayed, they are the last known pressures that were sent to your TPMS by the sensors in your other set of wheels. Is that other set of wheels/tires/sensors stored in your garage where your car will pick up signals from them when it's parked?

Even if your old sensors are not in your garage, your TPMS will retain the last known pressures and allow you to turn off AH or go into Comp mode.

However, if you lose power (like when I disconnected my battery) you may have problems and not be able to go into Comp or turn off AH.

Here's an excerpt from the Owner's Manual for a 2007, and it's the exact same thing that the 2007-2011 manuals all say:

The 2005 and 2006 manuals say the same thing except instead of "30 minutes" the 2005 and 2006 manuals say "60 minutes".

Like it says, if you don't have sensors and drive your car for that period of time (30 or 60 minutes, depending on model year) you will not be able to turn off AH or go into Comp mode.

That 30 or 60 minutes is one ignition cycle without shutting down the car. During that period of time you will be able to turn off AH or go into Comp mode, however if you are in Comp or have AH off when that period of time runs out, the AH will automatically come back full on.

If you do drive that long and get the "Service Tire Monitor" message and are not able to go into Comp or turn off AH, all you have to do is shut down the car, start it back up, clear any messages, and you'll have another "about 30 (or 60) minutes" where you can run in Comp or with AH before you'll have a problem again.

So.....I think if LEAVINU is running with no sensors, he's got about 30 or 60 minutes of driving time before any problem will arise, and if it does you don't have to use any special technique - just shut down and restart to get another 30/60 minutes.

Butt.....YMMV!!! Different model years react seem to react slightly differently to running without sensors.

When I go without sensors such as when I put my slicks on I get right at 60 minutes with no warnings. But after 60 minutes of steady driving I get the message and only TC off.

I've been driving with my drag pack all week. I noticed that if I shut the car off before 60 min I can restart with no messages as many times as I want. But I can't go over 60 min of steady driving or I get the message and it comes back each time until I go home and park in the garage next to my wheels.

Another thing. I once had a intermittently bad sensor that would say I had a flat when I did not. When that would happen I the car has a secondary speed limiter in the tune that limited to 65 IIRC though it said 55 on the DIC. I have disabled that speed limiter in the tune so it didn't matter. For that matter I have disabled traction control in my tune too. It says it's active on the DIC but it's not. I cannot disable AH with HP Tuners.

 

Bob,
If I am reading this correctly you never got the "service tire monitor" message on the DIC? This is key to this trick working from my experience. For example I recently disconnected my battery and was then unable to get in comp mode. I had no service tire monitor message and I still was unable to get comp mode. Assuming since I haven't had sensors for years there is no air pressure stored in the computer to pick up from. After a few drives I got the service tire monitor message and at my next restart I tried what I mention above and comp mode appeared right away.

I sold my sensors 4 years ago and always clear the service tire monitor message at each start-up. Not sure where the whole restart comes from to get back into comp mode, that's not an option with no sensors that simply. Maybe this does have something to do with the reading of the tire pressure on the DIC. My DIC has displayed "xx" for the past 4yrs and I can tell you I've never been able to drive in comp mode unless the engine didn't fire the first time.

To your point of it not working or there is no real work around to not having sensors is not a true statement. I haven't had sensors since 2006 and ever since I've been doing the above method I get all TC/AH settings like a showroom car would. Not sure why you would just have one sensor in the car or wheels with sensors in them near the car, that's unnecessary. Seems to me even though the sensor is reading zero it's confusing the computer more than if you didn't have it in the car, hence the flat tire message.

Try removing the sensor, drive till you get the service tire monitor message, shut down the car and try my work around. Let us know.
