What are the potential issues and necessary precautions when disconnecting the battery and handling the Engine Control Module (ECM) on Volkswagen Passat?

Battery disconnection may cause problems with driveability, which could only be solved with the help of a scan tool, and the battery disconnection may also activate warning lights on the instrument panel, which should also be turned off by a scan tool. The majority of the scanning devices available to the general public do not have the ability to resolve these issues, so that once any service has been performed on the vehicle the vehicle would have to be transported to a service department at a dealer, or an authorized repair shop with the ability to resolve these issues. To ensure the safety of your vehicle against any damages caused by the statical electric, ground yourself to the body of the vehicle before touching the Engine Control Module (ECM) in addition, store the ECM on a special anti-static pad after extracting it. In changing the ECM to a new unit, it is necessary to program it by a dealership service department or a repair facility using a V.A.G. 1551 scan tool. The process to take off and install the original ECM is by disconnection of the negative battery terminal, the availability of the activation code of the anti-theft radio, removing the cover of the ECM housing, prying off the ECM retainer clips, the disconnection of the electrical connections of the ECM, and vice versa.
