After a week of not using the 04 CT, as I drove out of the basement parking my tranny indicator on the dash got stuck looking this way...



All the P R N D letters are highlighted and no M appears if I shift the stick to manual mode. There is also no halo around the numbers 1 2 3 4 5 6 when the CT shifts gear.

The CT seem to drive OK and seem to shift just fine - even the tiptronic seem to be responding and shifting as it should. Its just the indicator lamps are frozen to this status. Is it a dirty actuator connectors or something else? Anyone had the experience already? Kindly share. TIA!

 

I haven't heard of that issue before. If it is just the display on the cluster, then I would try to use a Durametric cable (if you have one) to reset the instrument cluster. And clear the errors from the rest of the ECUs.

 

I wonder if disconnecting the battery for a little while might help - perhaps it'll reset. Just a thought...

 

Thanks for all the inputs guys! I believe mine actually went on limp mode as you have mentioned. I was on my way to the dealers and when the service manager re-started my CT, we were all surprised to see this...



At least for me it was a pleasant surprise :-) what really happened here? What is limp mode anyway? How do you cure this limp mode thing? Maybe you guys know the secret. Hope you could share.

 

My Cayenne sometimes does quarky things when it comes to electrical widgets. That is why my first thought is to try to clear the error to reset it and see if it comes back before going through the hassle of taking it in.

No different than having to reboot your computer or smartphone when it starts acting weird.

That is the cost of having so many cool gadgets.

Glad to see that you got it to work without too much trouble.
