Peugeot 508 Alternator Replacement Parts

The Peugeot 508 first generation ran from 2011 to 2018, with a facelift in 2014, so both years sit within the same generation — but the facelift introduced some under-bonnet revisions, and whether those affected alternator mounting or ancillary brackets is something you should confirm with the breaker against your registration. The safest approach is to supply your engine code (found on your V5 or via a VIN check) so the breaker can match on that rather than year alone. Never assume fitment purely on generation without that check.

No — fuel type is a primary fitment factor for alternators, as diesel and petrol engines are fundamentally different units with different electrical demands and physical configurations. An alternator sourced from a 2.0 HDi diesel will not be the right part for a 1.6 PureTech or 2.0 petrol engine. Always specify your exact engine code when requesting a quote from a breaker.

Trim level does not affect alternator fitment on the 508 — Active, Allure, and GT are all cosmetic and equipment grades that share the same mechanical underpinnings when the engine code matches. The alternator follows the engine, not the badge, so a part pulled from a lower-spec Active with the same engine code as your GT is mechanically the same unit. You may notice cosmetic differences on stripped parts from higher trims, but none of that affects whether the alternator itself fits or functions.

The 2014 facelift is a known boundary for the first-generation 508, and while the core engine architecture often carries across, ancillary and mounting changes introduced at a facelift can affect whether a direct swap works without modification. You should name this boundary explicitly when speaking to a breaker and ask them to verify compatibility against your specific registration and engine code. Do not assume pre- and post-facelift alternators are interchangeable without that confirmation.

Gearbox type can influence alternator specification on some applications, as automatic transmissions may place different electrical loads on the charging system. It is worth telling the breaker whether your car is manual or automatic alongside your engine code to make sure they are pulling from the right donor vehicle. Confirm this detail rather than assuming any same-engine alternator will do.

PSA Group engines like the 2.0 HDi were shared across Peugeot and Citroën models, and in some cases alternators do interchange, but mounting brackets, ancillary routing, and connector types can differ between vehicle platforms even with an identical engine code. Give the breaker both registrations and let them cross-reference the part numbers before committing to a purchase. Cross-platform swaps are possible but need explicit verification — never assume on shared-engine grounds alone.
