First of all if you thinking about installing the chip yourself I recommend not doing so unless you have the cash in hand to replace the potentially fried TCU.
I choose to install myself since my occupation is electronics driven (not much SMD components though).
Removed the TCU and popped it open...WTF?
Removed and soldered in the MTM. (GIAC is not in my vocab)
(MTM sticker removed for "OEM" appearance)
Now comes the Oh S*** moment; reinstalled the TCU, turned the key to run and "Press Clutch Pedal to Start Engine" is shown on the DIS. F***.
Scan with Vag-com, no TCU communication.
Pulled out TCU again, Ran the soldering iron over the pins again, and checked continuity between the pads and the pins on the chip; all good.
Reinstalled and tried again.....SUCCESS! RELIEF!
Replaced all the vacuum lines under the Intake and called it a night.
