I was searching through the forums and found this thread. Sorry for starting a new one admins. I think I have the same problem...

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!

Can we have an update on how this problem was solved? Any DIY photos would really be appreciated. Thanks in advance!

 

Earlier in this thread the above comment was made and it helped 3 people that I know of. I would bet it's the same for you.

 

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.

 

Looks like good news for you. Only if it doesn't come back again. John

 

Hi I have a ctt 04 and today was driving along came to park put it in park on the selector and the display stayed as R and I couldn't remove the keys had to move the gear selector back to N then turned the key off and it asked for me to select P and after a couple of times I could remove the key.

Now when turning on the key the dash says R when the selector is in park and cannot start the car just had to get towed.

Car doesn't start and read this article on sun shade, isn't this a piece of plastic how can it cause such issues please help
