OEM Part Number: 9666997980

Genuinely distinctive to know: this alternator reference is shared not just across the wider Peugeot/Citroen range but also, from the era PSA supplied engines to BMW, the Mini Cooper S — an unexpected cross-manufacturer link worth knowing if you're cross-shopping parts availability.

150 Amp, Valeo, shared across 1.6-litre petrol/HDi diesel range	Genuine cross-reference: 9666997980 (also referenced as FG15T072, TG15T072) — fits Peugeot 208/308/3008/5008, Citroen C3/C4, and Mini Cooper S of the relevant era

Confirmed: A Genuine Recall for a Software Fault — Not the Alternator Itself — Peugeot 208 Alternator

This is genuinely important to know before spending money on a new alternator: Peugeot confirmed a recall (reference HNZ) covering the 208 and 2008 specifically, addressing a possible non-compliance in the engine control unit's software that can disrupt battery charging. This is a genuine software fault, not a hardware failure in the alternator itself — and it directly explains a well-documented, frustrating pattern reported by multiple owners: replacing the alternator, sometimes more than once and at genuine dealer prices, without the charging fault actually resolving, because the alternator was never the actual problem. If you're experiencing a charging fault, checking whether this recall applies to your specific car via your VIN is worth doing before authorising any alternator replacement at all.

A genuinely useful diagnostic test worth doing first: these "smart" alternators are controlled by the engine ECU via a LIN-bus signal wire rather than charging at a fixed voltage. If you disconnect this signal connector at the back of the alternator and charging returns to normal, this confirms the alternator and wiring are genuinely fine, and the fault lies in the ECU software or its communication with the alternator — not the alternator itself. This single test can save you from an unnecessary, expensive replacement.

Peugeot 208 Alternator: Often Blamed on the Battery Instead

Early on, a weak Peugeot 208 battery and a dying alternator look almost identical — dim lights, sluggish starts, a car that won't hold its charge — which is exactly why so many people fit a new battery and end up back at the garage weeks later, the actual fault still unaddressed.

Before you buy: alternator output rating varies by engine size and trim, particularly on cars with more onboard electronics. Always confirm against your VIN before ordering.

Peugeot 208 Alternator: What It Does

On the Peugeot 208, while the engine runs, the alternator generates the electricity that charges the battery and powers the car's electrical systems directly. With a healthy alternator, the battery's real job becomes starting the engine and covering brief demand spikes, rather than running the electronics on its own.
