Got a stereo system and want more power? wont help need to go with dual batteries, or capacitors. everyone should have a manual for their vehicle, and the library should have a professional shop manual available in the REFERENCE section...make copies of the right sections...good luck :)
Yes you can if the battery is the problem. connect the red on car with good battery to the positive ( + ) terminal, then the red on the dead battery, connect the black to the negative ( - ) on the good battery and the black to a good chassis ground( exposed metal in engine bay ) a good spot is the strut mount bolt.
To replace the battery in a 2003 Passat 1.8 Turbo, first ensure the vehicle is turned off and the keys are removed. Disconnect the negative terminal (black) first to prevent electrical shorts, followed by the positive terminal (red). Remove any securing brackets and lift out the old battery. Place the new battery in the tray, connect the positive terminal first, then the negative terminal, and secure everything back in place.
On a Passat, the battery is located under the hood. It is under the cowl panel and requires the removal of the battery cover to see it.
To replace the car battery on a 2014 Volkswagen Passat, begin by turning off the ignition and ensuring all electrical components are off. Open the hood and locate the battery; remove the negative (-) terminal first, followed by the positive (+) terminal. Take out the battery hold-down clamp and carefully lift the old battery out. Place the new battery in the tray, secure it with the clamp, and reconnect the positive terminal first, followed by the negative terminal.
No it will not restart
AAA

On the 2006 passat it is under the hood in the battery box. On some passats it is located in the trunk on the left side (US driver) behind a cosmetic panel.
By the firewall (far back, center), simply slide the battery cover to reveal the actual battery.
Use a cable and software from VAGCOM.
