Drivers side of the transmission, There's a shift cable attached to it. Bit of a pain to remove without a hoist and requires adjustment after installation.

I went underneath but it was all covered with bolted plate I could not see anything.did you unbolt all the plates to reach it?I just want to see if the connector is loose or disconnected or use multimeter to check if the electrical signal is right.is there any easy way to reach it without that much hassle?is it better if the car is hoisted?if hoisted,can we reach it and check the condition?do we have to take some parts off to reach it?
appreciate your info.

1. Hoist
2. Metric tools including Allen keys
2. Vag-Com as the diagnostic tool for adjustments

Look at the image, that should help.
