Vehicle Battery 5K0-915-105-E

OEM part 5K0-915-105-E is used primarily on Volkswagen Golf VI (Typ 5K, 2008–2013) and related PQ35/PQ25 platform vehicles, including the VW Jetta VI (A6), VW Golf Plus (5M), VW Touran (1T) in certain configurations, and selected Škoda and SEAT models sharing the same battery bay dimensions. Always verify using your full VIN, as battery specification varies by engine, market and optional equipment (Start/Stop, premium audio, tow hitch).

In most cases, yes — within limits. A battery with higher CCA (cold cranking amps) or slightly higher Ah capacity (e.g. 72–74 Ah) is generally acceptable if it fits the battery tray and has the same terminal layout. However, significantly oversizing the capacity (e.g. going from 70 Ah to 100 Ah) is not recommended without verifying that the vehicle's alternator and charging system can handle it. Higher-capacity AGM or EFB batteries should only be fitted if your vehicle was factory-equipped with a compatible charging management system. When in doubt, match the original 70 Ah specification.

Battery coding (also called battery registration) is required on Golf VI and Jetta VI models equipped with Battery Energy Management (BEM) — typically vehicles with Start/Stop systems or factory-fitted tow hitches. Without coding, the BCM (Body Control Module) continues to use the charge profile of the old battery, potentially under- or over-charging the new one and shortening its life. Coding is performed via VCDS (VAG-COM) or a compatible OBD-II tool under "Adaptation" in the BCM module. If your vehicle does not have BEM, coding is not required, but is still good practice after any battery swap.

The suffix letter (A, B, C, D, E…) in a VW OEM part number typically indicates a design or specification revision. Within the 5K0 915 105 series, different suffixes may reflect changes to terminal design, capacity rating, or the introduction of a maintenance-free casing. The "E" suffix is the current or most recent revision in many catalogs. Earlier suffixes (A–D) are generally superseded by "E" for replacement purposes, but always confirm with your VIN or a VW dealer parts lookup before ordering to ensure you receive the correct specification for your exact vehicle build.

Yes. Varta Blue Dynamic E23 (part number 570 412 063) is a confirmed direct aftermarket equivalent for OEM 5K0-915-105-E. Varta is the OEM battery supplier for Volkswagen Group vehicles and the Blue Dynamic E23 shares the same 12V / 70 Ah specification, physical dimensions and terminal layout. It is widely listed in Varta's own VW fitment catalog for Golf VI and related models. The Varta Silver Dynamic E39 (74 Ah) is an alternative if a slightly higher reserve capacity is desired and the battery tray allows the marginally larger footprint.

On VW Golf VI and Jetta VI, power windows lose their one-touch (auto-up/auto-down) function after the battery is disconnected. To recalibrate: close each window fully by pressing and holding the switch until the window reaches the top, then continue holding for an additional 2–3 seconds. Release, then pull up briefly and hold again for 2 seconds. Repeat for each door. The sunroof (if fitted) requires a similar procedure — refer to your owner's manual for the exact sequence, as it varies slightly by model year and trim level.
