yeah, it's odd b/c the window overall functions fine. I read some threads on window limit adjustment- I might try lowering the glass 1mm to see if it fixes the issue. but I have to find a special reverse torx socket correct?

I would like to know as well- Is it a standard LED or a small bulb?

Thanks Loren!

2002 C2 coupe w/ bose speakers and bose amp. I'm going to pull the factory radio and install a kenwood double-din dvd-nav unit. For now I will retain the bose amp and speakers, I would like to send the 2v low-level RCA outputs of the kenwood to the bose amp's inputs. Anyone have access to the radio and amplifier wiring schematic? Would be highly appreciated!

yep- The tip's installed from MY02 forward are very different from the earlier variety. IIRC, the '02 and up tiptronic is the same version used in the Turbo. 250 different shift maps vs. the earlier tips' 5 programs. This is an excerpt from the MY02 service information manual: "The Tiptronic control unit determines the driver’s current requirements on the basis of the incoming information and then changes to an appropriate map. In contrast to previous transmissions, the new Tiptronic control unit has 250 different shift maps instead of just five. The maps permit virtually step-less adaptation." ...anyway, yeah it might be a long shot but will still be fun to investigate -

actually- I found this out from the service information manual which describes the tiptronic operational characteristics: ? Warm-up map A warm-up map which is activated at engine temperatures < 32 °C is integrated in the stepless shift map adaptation. In the warmup map, the shift-up points are offset to higher engine speeds, the transmission starts in 1st gear and the torque converter lockup clutch is opened. If the reverse gear is engaged during the warm-up phase, the vehicle starts in a short reverse gear. These measures result in both the engine and catalytic converter rapidly reaching their operating temperatures. Unlike previous transmissions, the new Tiptronic transmission shifts back into the first gear if the vehicle is started in first gear and then stopped again. (umm, not really...) In addition, if the selector lever passes through "N" as it is moved to a different position, the first gear is always engaged for approx. one second, irrespective of temperature. If the vehicle is driven off during this time, the transmission shifts into the first gear. Now, this i have confirmed is a much perkier driving mode, but unfortunately the tip switched back to 'sloggy 2nd gear mode' and did not hold the gears as high after the engine temp gets to 1/4 on the guage. Ideally, if there is some way to DIY a button that tells the signal wire to place the tip back into warm-up map, this would be stellar. Try it out with your tip when it is cold- Do a drive-off in D, and you will see what I mean. It is a noticeable difference. The point that I italicised above does not seem to work for me when the car is warm, only when the car is cold, so I'm not sure if this is really supposed to work or not after the engine temp is over 32c. Can anyone out there assist with tracking down the signal wire that tells the tip when the engine is over x degrees? also need to know how this wire receives the signal and what type of signal it is.. I'm willing to test this mod out on my car, if it pans out this mod might benefit a lot of tip drivers.

think this might be regulator-related?

now that is interesting... I went out to look at the curve as you suggested, and it seems to be 100% accurate on the curvature alignment. I worked the drop up and down with my hand a few times (pulled the glass up and pushed down several times the 1/2 inch travel), and now it seems to work fine. I opened / closed the door various ways trying to trip it up and it is ok. So maybe it was just sticky from not being used much... lubrication might be in order. Will see if it stays ok or starts giving me problems again- Thanks for your help!

ah hah! I see exactly what is going on now. Was outside messing with it for a bit. It is supposed to drop 1/2 inch on door open. It is only dropping 1/4 inch sometimes, far enough to open the car door but causes binding when closing the car door. if I open the door and it drops 1/4 inch, I can push the glass down the remaining 1/4 inch but there is some resistance, almost like something is not lubricated and allowing the glass to drop the full 1/2 inch. Thoughts on what this might be before I go ripping the door apart?

Thanks very much Loren- Yeah everything else seems normal. The window does drop the 1/2 inch on open and stays down while the door is open. The messed up part is it pops back up too soon before the door is fully closed, so it seems that the timing is off. So I guess it would be the switch that tells when the door is shut? Would you happen to know (or know where the resource is) that shows this door close switch location?

There may be a thread on this here but I could not find it- Basically, every 3rd or 4th close of the passenger door on my coupe does not seat the window properly in the channel, it stays popped outside of the rubber top trim. It seems that the window is not dropping down fast enough before the door closes, and I have to re-open the door once or twice to get it to close with the corect timing. Is this a switch adjustment? My car only has 29k miles on it. any help would be appreciated. (and I have tried re-setting the window by rolling all the way down / all the way up)

2002 C2 coupe, tiptronic trans, 29k miles, no mods... yet :) Under normal "D" mode, I have noticed that by default the car starts out in 2nd gear from a stop. also, when cruising the transmission always rolls up two gears and I find myself on the brakes way too often. On my now-departed Dinan 330i, I upgraded the tranny with the Dinan software which allowed the car to start from 1st and held the gears until a higher rpm had been obtained, and also downshifted the trans much quicker when slowing down. Are there any software upgrades or programming tweaks avail for the 996 tiptronic? I do know that the seller took the car to the local Dallas Porsche dealership for an inspeaction before we completed the sale (I just bought the car), and the dealer discovered that the tip control module was not functioning properly- So they replaced it. (yeh, yeah.. I know.. A stick woulda been more satisfying, but hey I got a great deal and it's still fun.) Thanks all in advance for any info that you might have-
