Latest Firmware Update- I have shift lights again and more!!

Since my car was updated almost a year ago, I have had the shift lights go off every time I turned off the car. It required a manual reset every restart- a royal PITA. Apparently this was a problem with non I-Drive DCT cars.

Well, I just picked my car up from service today, and a complete flash of the firmware was done and the shift lights are on permanently. The good news doesn't end there though, although it has only been a couple of short drives I have noticed the following improvements:

1. S4 mode is more direct- the extreme and sometimes annoying 'power pulse' on upshift is replaced what feels like an almost perfect gear change- yes it still has a little bit of a pulse at upper RPM's but very slight and not like before where it was enough to get the back end out of shape. The best news at partial throttle up shifts at 4-5K the shift is smooth like S3- very nice, almost the perfect mode now with double clutch downshifts and smooth upshifts when cruising and crisp upshifts at full throttle. I like!

2. The slow speed start assist has been 'tamed'. After the last firmware update a year ago, it seemed the start assist would be too aggressive in stop and go traffic or just coming to a slow stop. The old firmware would hold a higher RPM, like 1.5K or so and make a smooth stop difficult. I felt like this was a way to combat the lag issue- keep it in gear and keep the RPM's up so there was no lag if you decided not to stop and re accelerate. Now, it behaves much better, slow stops are close to normal with no higher revs and a smooth start much easier because the revs aren't up and it seems the car releases the gear as you come to a complete stop- much improved!
(FYI- I never had lag and rarely run D modes).

3. Can't confirm this 100%, but the cold start seems to be better. Before, even after just a few minutes the car would take a minute to settle into a smooth idle on a cold start. So far not noticing that anymore, but we'll see in the morning...

So far, so good. Not sure how I lost my voice name memory, but still have all my radio and XM stations programmed, but oh well!

Last but not least, I don't have the version, my dealer does not give out that information- Sorry. I will say that the firmware update was done specifically to address my shift light issue and the fact my radio had locked up a couple times. Not for the DCT.

I agree with all of your statements. Very welcome changes. My DCT is now behaving like it should have 18 months ago.

Sorry, but I don't have that information. It must be the latest- as far as I know the shift light issue was not addressed in previous versions.

This is awesome! Do you know if the fact that the software fixes the shift light reset issue is documented anywhere? Because that will be very easy to demonstrate, and means no begging, pleading, bribing to get the latest update. I personally don't really care that much about the shift lights, but this should be just the ticket to getting the latest update.

On my repair invoice it refers to a SIB for the radio. For the shift lights it says it is repaired by the firmware update, no reference to a SIB.

it doesnt' bother me at all cuz I know how the clutch on the DCT modulates and its easy to predict. But refer to the DCT lag thread I've made a few posts in the last few pages, I have a minor 0.5 sec at most, lag...
its there, doesn't bother me. would be perfect if its 100% gone.

Can you post the SIB number, or do you know if there is a separate thread here with a discussion on it?

Base radio, right? (I am almost positive the premium radio requires I-Drive.)

I would just anticipate it till it goes in for service and get them to test drive it with you in the car showing exactly what you mean to them, this should get the desired results.

Yes, Base radio with satellite radio and USB. I don't have the repair invoice here so I don't know the SIB. Will post tonight.

Locks up, can't be reset without turning off the car. It happened a couple of times.

Cool. That's happend to me a couple times, and I've had the radio stay on after I turn off the car while on Blutooth. BT doesn't turn off even after the call is ended and I'm out of the car.
