Volkswagen Touran Battery: Specs, Fitment & Common Faults

A genuine, well-documented VW Group requirement: the Touran's replacement battery needs to be "coded" to the car's Gateway module — here's what that actually involves.

OEM Part Number: 000915105DE

Genuinely useful to know: Touran genuinely shares its platform with the Caddy and parts of the Golf V, so genuine cross-reference part numbers exist across all three — worth checking if the exact Touran listing isn't in stock.

Genuine reference (also cross-referenced as 000915089E, 000915105DD, 5K0915105D)	VW OEM: 000915105DE — 280 CCA
1.6/2.0 TDI diesel, standard fitment	242-243mm case, minimum 59Ah, lead-acid
Start/Stop variants	AGM technology, 70-72Ah, 720-760A (EN) — a standard lead-acid battery isn't sufficient for the frequent cycling involved

Confirmed: Most Tourans Genuinely Need the Battery "Coded" After Replacement — Volkswagen Touran Battery

This is worth understanding before assuming a simple swap is the end of the job: VW Group vehicles with a Battery Management System (essentially any model with stop-start) need the new battery's details — capacity, chemistry, and serial number — registered to the car's Gateway module, a process usually called battery coding or registration. Skip this, and the car's charging strategy keeps assuming the old, worn battery is still fitted, which can lead to overcharging or undercharging the new one and shortening its life prematurely. This can genuinely be done with widely available aftermarket tools like VCDS or OBDeleven, not exclusively at a VW dealer with their ODIS system — worth knowing if you're comparing quotes or considering doing it yourself.

A genuinely useful, specific detail: the coding process reads a Part Number, Vendor Code, and Serial Number printed on the battery's own label — budget or generic aftermarket batteries sometimes lack a valid one of these, which can cause the coding process to fail outright. If a battery's exact new part number is rejected during coding, using the original (pre-supersession) part number instead sometimes resolves it. Genuinely worth choosing a battery from a reputable supplier with proper VAG-compatible labelling rather than the cheapest generic option specifically for this reason.

Volkswagen Touran Battery: The Part Everyone Blames First, Not Always Correctly

When a Volkswagen Touran won't start, the battery is the first suspect more often than anything else, and it's right often enough that checking it first is a reasonable move. It isn't always the actual cause though, which is worth knowing before paying for a replacement that solves nothing.

Before you buy: battery size, capacity and type (standard vs AGM/EFB for stop-start systems) vary by trim and engine. Always confirm against your VIN before ordering.

Volkswagen Touran Battery: What It Does

Starting the engine and running electrical systems whenever the engine isn't turning — that's the Volkswagen Touran's 12V battery job. If it has stop-start, it works much harder than older designs, since the engine cuts out and restarts constantly, which is exactly why it needs a specific AGM or EFB battery rather than a standard one.
