Porsche 991.1 & 991.2 Carrera and Turbo PDK Removal
These instructions will explain the process for removal of the PDK/TCM module on Porsche 991.1 and 991.2 models. Removing the PDK controller (TCM) is required when the Accessport detects that an unsupported ROM has been found during PDK installation. Due to the large number of ROM versions, we unfortunately can only acquire these by saving them directly from the TCM physically in-house. The PDK TCM is located under the rear passenger seat and can be removed using minimal tools and just a little effort! Please review steps and tools needed BEFORE getting started.
If you feel that you cannot properly perform this removal, we HIGHLY recommend you take the vehicle to a qualified and experienced automotive technician.

Instructions for TCM Removal
Preparation
Make sure the car is parked in a location where it can sit until the TCM is reinstalled. If the car needs to be moved or pushed while the TCM is not in the car, leave the car in the "N" Neutral position so you can push it. Failure to put the car in "N" Neutral before you remove the TCM will keep the car stuck in the "P" Park until the TCM is installed again.
Move both front seats to the forward position and lean seats forward to give ample room to work in.
Disconnect the battery terminals under the hood in the frunk.
Rear Seat Removal
Remove the lumbar pad from the seat. It is held on using Velcro and will pull off quite easily.
Remove the rubber insert from the rear seat storage tray. You can use a trim tool or dull flat-edge and pull it out from the rear.
Unclip and remove the plastic covering for the securing bolt. Undo the nut that is now exposed using a 13mm socket.
Remove plastic seat belt buckle covers with a trim removal tool.
Remove the seat belt buckles with a 16mm socket.
Remove the rear seat. It is held in with velcro and the lips of trim pieces. It may require some tugging in various directions but will come out. Set aside.
