DSG Transmission MECHATRONIC -J743- Circuit Boards: Removing

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 Audi S5, 2014 Audi S5, 2013 Audi S5, 2012 Audi S5, and 2011 Audi S5. However, it is still accessible from the selected car via links, so may be relevant.

-- Remove Direct Shift Gearbox (DSG®) transmission Mechatronic --. Refer to DSG TRANSMISSION MECHATRONIC -J743- .

-- Place the Mechatronic on a clean, soft surface.

CAUTION:

There is a risk of destroying the transmission control module (Mechatronic) with electrostatic discharge.

Always "discharge" the static electricity. Do this by touching a grounded object, for example vehicle ground, the vehicle or the hoist.
