Second Hand Mercedes-Benz Sprinter Alternator

This question spans the W906 generation (2006–2018) and the W907 generation (2018 onwards), which are fundamentally different platforms, so a direct swap is unlikely without careful checking. The engine code is the deciding factor — even if both vans share a similar diesel engine family, ancillary mounting and electrical configurations can differ between generations. Name the engine code from your V5 or a VIN check when contacting a breaker, and confirm fitment against your registration before purchasing.

The engine code matters above everything else for a Sprinter alternator — year alone is not sufficient because Mercedes-Benz used several different engine variants across overlapping production periods. Two Sprinters built in the same year can carry different alternators depending on which engine code is fitted. Pull the engine code from your V5 logbook or a VIN check and give it to the breaker alongside your registration for an accurate match.

No — fuel type directly affects alternator specification, and a petrol-sourced alternator should not be assumed to interchange with a diesel application. The Sprinter sold in the UK was overwhelmingly diesel, so petrol units are rare in the breaker market, but the principle stands. Always confirm the fuel type and engine code match when sourcing a used alternator.

Trim or body variant does not affect alternator fitment — what matters is the engine code, fuel type, and gearbox type, not whether the van is a Panel Van, Tourer, or another body style. You may find cosmetic and interior differences between variants, but the alternator is determined entirely by the drivetrain. Confirm the engine code matches and check with the breaker against your registration.

The W906 ran from 2006 to 2018 and received a facelift in 2013, but the key fitment question is whether the engine code and output rating are the same across that period, not simply the facelift year. Within the same engine code, many alternators are shared across the generation, but ancillary mounting or connector changes mid-production can catch buyers out. Name the exact engine code and year to the breaker and ask them to confirm fitment against your registration before buying.

Gearbox type is a relevant fitment consideration for a Sprinter alternator because automatic variants can place additional electrical demands on the charging system, and the alternator specification may differ accordingly. It is not safe to assume a manual-sourced unit automatically crosses over to an automatic van or vice versa. Give the breaker your gearbox type alongside the engine code and registration to make sure the specification matches.
