Each row groups the versions that share an engine. When an engine lists more than one battery, it is because the battery changes with the version or equipment: your number plate settles it.

With Start-Stop: versions with automatic engine stop-start, or that leave the factory with an EFB or AGM battery. Ah = capacity; A = cold cranking current (EN standard); + right/+ left = side of the positive terminal. Under each engine you will find its engine codes, handy for identifying your version.
What you should know about the Volkswagen Passat B6 3C
This page covers Passat B6 (3C2) and Passat B6 Variant (3C5): 17 engines in the table, petrol (9), diesel (7) and gas (CNG/LPG) (1). Only part of the range has Start-Stop (7 of 17 engines): those versions need AGM, the rest a conventional battery. The usual case size is L3 (278 × 175 × 190 mm).
- Model fact: the Volkswagen Passat B6 3C mainly uses case sizes L3 (278 × 175 × 190 mm), L2 (242 × 175 × 190 mm) and L1 (207 × 175 × 190 mm). A battery of a different size will not sit securely in the car’s battery tray.
- General tip: if your car came from the factory with an AGM battery, replace it with another AGM; if it has an EFB, with an EFB or an AGM. A conventional battery in a Start-Stop car wears out much sooner and the system may stop working.
- General tip: on Seat, Volkswagen and Audi models with Start-Stop, the new battery is usually coded into the energy management system with a diagnostic tool, so that the alternator charges it according to its type and capacity.
- General tip: mid-size and executive saloons keep drawing power while parked (alarm, telematics, comfort systems). If the car goes weeks without being driven, a battery maintainer will extend the life of the battery.
