Symptoms:

- Car will not start, when I turn the key it doesn't crank or anything. You can hear the fuel pump, but no activity from the engine/starter.
- Lights, headlights, electronics, etc come on normal
- DIS indicates "Press Clutch Pedal to Start Engine" which is obviously wrong as there is no clutch pedal on the tiptronic
- VAGCOM cannot access the TCM (Controller 02-Auto/Trans)
- VAGCOM Fault Codes:
01-Engine
049409 - No Communication with Transmission Control Module
U0101 - 008 -
Freeze Frame:
Fault Status: 01101000
Fault Priority: 0
Fault Frequency: 1
Mileage: 167870 km
Time Indication: 0

Freeze Frame:
RPM: 0 /min
Load: 0.0 %
Speed: 0.0 km/h
Temperature: 32.0°C
Temperature: 30.0°C
Absolute Pres.: 1010.0 mbar
Voltage: 11.938 V

Questions:
- Where is the Transmission Control Module on the Tiptronic? I believe on the CVT it is in the transmission
- Are there any fuses or relays that would result in the module not getting any power?
- Does anyone have any recommendations on how to troubleshoot this?

TIA

I had the same issue. Go search for an after market extended warranty. You need a whole tranny. Or just the 2000$ valve body. After labor and parts, an extended warranty will cost you less. Plus you can pay it off over 18months and other parts will still be covered even after the repair. Only issue is that you will have a 30day wait period. You can email me is you have more questions

Thanks for the reply. Anyone else have any thoughts? Is there any way I can check whether or not the TCM is actually getting power?

There are a couple other electrical issues that I've since identified that are odd.

1. Fuse #41 used to be hot only with ignition, it is now always hot (I use this for radar detector/power on line for radio)
2. The rear trunk release button doesn't work

Both of those occurred at the same time as my transmission issue.
