OEM Part Number: confirm via VIN — alternators (aftermarket) Bosch 0 986 082 240 / Valeo 440350

Accuracy note: Covers the Peugeot 2008 (2013-2019) as listed in the UK aftermarket catalogues. Alternators are sold by output (amps), pulley type and plug, and the same model usually has two or three units depending on engine, start-stop and the electrical load of the trim — a 120 A unit on a car built for 150 A will undercharge, and a rigid pulley on a car designed for a freewheel clutch pulley will shred belts. The references below are UK aftermarket catalogue listings for this generation, labelled by brand; many are remanufactured exchange units that carry a core charge until the old alternator is returned. Genuine numbers are shown only where a listing quotes one. Check the amp rating, pulley and plug stamped on the old unit, or confirm via VIN, before ordering.

Alternators (aftermarket)	Bosch 0 986 082 240 (150 A, freewheel pulley, 6 ribs, 54.5 mm, remanufactured exchange, plug 132, core charge £50.24, excludes vacuum-pump versions); Valeo 440350 (120 A, freewheel pulley, 6 ribs, 55 mm, remanufactured exchange, core charge £50.24); Valeo 444706 (150 A, freewheel pulley, 6 ribs, 54 mm, remanufactured exchange, B+/COM plug, core charge £50.24); Valeo 439845 (180 A, rigid belt pulley with V-ribbed pulley, 6 ribs, 52 mm, new, stop-start vehicles only); Denso DAN1071 (90 A, freewheel pulley, 6 ribs, 54 mm, new); Lucas LRA03457 (150 A, freewheel pulley, 6 ribs, 54 mm, remanufactured, plug 0223, core charge £50.24); Lucas LRA04437 (180 A, freewheel pulley, 6 ribs, 54 mm, remanufactured, COM/LIN 1-2-2A plug, core charge £25.12, Euro 6.2 engines).
Outputs & variants	Four outputs are listed. The 90 A Denso suits the base 1.2 VTi petrol; the 120 A freewheel units (Valeo 440350, AS-PL A5104, Ridex 4G0338) fit the 1.2 PureTech and 1.4 HDi without stop-start; the 150 A 54 mm freewheel units with the COM/LIN plug are the standard 1.6 e-HDi/BlueHDi diesel fitment; and the 180 A Valeo units (439845, 439965, 440999) with a rigid pulley and 52-53 mm diameter are reserved for cars with stop-start, where the alternator also acts as the starter-generator.
Genuine (OE) numbers quoted	439845 (AS-PL A3439 (VALEO), stop-start).
Fitment notes	Never fit a standard alternator to a stop-start car or the reverse, and check whether the original has a freewheel pulley before ordering; the Valeo 440999 stop-start exchange unit carries a £152.37 core charge and the other exchange units £25-£50, all refunded on return of the old part.

Confirmed: A Genuine Recall for a Software Fault — Not the Alternator Itself — Peugeot 2008 Alternator

This is genuinely important to know before spending money on a new alternator: Peugeot confirmed a recall (reference HNZ) covering the 2008 and 208 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 2008 Alternator: Often Blamed on the Battery Instead

On the Peugeot 2008, dim lights, slow starts, a battery that won't hold charge — these symptoms point equally to a weak battery or a failing alternator, and that overlap is why so many replacements target the wrong part first, with the real problem only surfacing weeks later.

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 2008 Alternator: What It Does

Electricity generation while the Peugeot 2008's engine is running is the alternator's job, charging the battery and directly powering the electrical systems. When it's working properly, the battery mostly just handles engine starting and short demand spikes, not day-to-day electrical load.
