I have a 2001 c4 tip and I noticed a couple of things that are a bit annoying:

1- it always starts in 2nd gear
2- there is a rattling noise at 30mph from the tranny when driving it slowish

I've read about both of these items on the forums and my understanding is that when driving in stop and go traffic the tiptronic adaption can adapt to unfavorable values (see this thread:

http://www.renntech.org/forums/topic...-higher-gears/

Two solutions are often proposed to deal with both of these issues a) drive more aggressively and b) reset the tip adaption through PIWIS. I've now done both and observed absolutely no difference.

The third option I've read about is installing a new Tiptronic control unit with updated software to address these issues (again see thread above). My question is this : has anyone on this forum ever done this and resolved these tip issues??

Thank you!

 

It is supposed to start in 2nd gear. If you are drag racing, just downshift by pressing the button. On the streets, you don't need to start from 1st.

I haven't heard or experienced the second issue.

Meshing the throttle will shorten the life of the transmission. You should replace the ATF if the car has over 70k miles. Tip is a pretty good transmission considering it's an automatic. It does learn and hold the rev as needed. But you also have those buttons too.

 

Thanks djantlive!
I googled "meshing the throttle" and didn't find anything. What does that mean??

 

I've only had my 996 for a few days now, but I dont mind it starting in 2nd (saves gas?). Most times I'm driving normal and 2nd accel just find for normal driving. If I want to go fast, just gotta tap the button down to 1st and I'm off!

Coming from manual cars my whole life its weird driving an automatic. I'm "learning" how to drive it, if that makes sense? The gears change pretty quick IMO.

 

meshing the throttle just means burnouts lol...

this heats up the transmission and causes premature wear. people who do this need to change the ATF 2x as much.

 

Thanks! Would still love to know if anyone did the tiptronic control unit update for the 2001 c4. Anybody?
