The SMG soft reset won't really help the "shudder from standstill" problem. Yours is a clutch-related issue, not an SMG gearbox-related issue as such.

I'm UK-based, so couldn't really advise where you can get the software locally. I'm sure a US-based forum member will be able to tell you where best to source this software. The software you need is something like INPA, NCIS, DIS, etc.
But a clutch recalibration is something best left to someone who has some knowledge of what they're doing with the software. If you're new to it, there's a risk of messing things up.....

No, the dealer won't sell it to you. As I said above, source it locally. In the UK, you can pick up the software and necessary cable for around 30GBP.

Not sure why this is, but someone else may know?

I honestly don't think a new clutch should be top of your list of solutions. Especially as your car is only 45k miles?!! Definitely try the above clutch recalibration first.

As I said above, this fault has little/nothing to do with your SMG gearbox directly. So the relay, the SMG cog light, etc are irrelevant here.
It is a clutch calibration issue!


Hope this helps!
