Cheap Alfa Romeo 159 Body Control Module

Yes, the Alfa Romeo 159 is fitted with a Body Control Module (BCM), which manages a range of electrical functions including lighting, central locking, and window operation. It is present across the 159 range, which ran from 2005 to 2011 in the UK as a single generation with no major mid-life architecture split. If you are sourcing a used unit, you will need to confirm the exact part number with the breaker against your registration, as software variants can differ.

The Alfa Romeo 159 was produced as a single generation from 2005 to 2011, so a 2007 and a 2010 unit come from the same platform and share the same basic architecture. However, BCMs are closely tied to the specific electrical specification of the car, including options fitted at build, and a unit from a different year may require coding or may not be directly compatible. Always confirm the part number and specification with the breaker against your exact registration before purchasing.

The Alfa Romeo 159 was sold in the UK in trims including Turismo, Lusso, and Ti among others, and while trim does not fundamentally alter the BCM fitment category, the options fitted to a particular car — such as parking sensors, heated seats, or adaptive headlights — can influence the BCM specification. A BCM from a higher-spec car may not behave correctly in a lower-spec car and vice versa, so trim-level differences are worth discussing with the breaker. Confirm the exact specification of any used unit against your registration rather than assuming trim-to-trim compatibility.

The engine type itself is not typically the primary driver of BCM specification on the Alfa Romeo 159, as the BCM mainly governs body electrical functions rather than powertrain management. That said, certain engine-specific features — such as those related to stop-start systems or specific wiring configurations — could influence which variant of the BCM was fitted. Confirm the part number with the breaker against your registration to be sure you are getting the correct unit for your exact build.

Used Body Control Modules almost always require coding or programming to the recipient vehicle, as they store data specific to the car they were originally fitted to, including key fob pairing and option configurations. Simply swapping a used BCM without reprogramming it is unlikely to work correctly and may cause fault codes or non-functioning systems. You will typically need a specialist with Alfa Romeo diagnostic equipment to code the replacement unit to your car after fitting.

When contacting a breaker on Findapart, have your registration number ready along with the part number from your existing BCM if you can access it, as this gives the breaker the best chance of matching the correct specification. The 159 ran from 2005 to 2011 as a single generation, but electrical build specifications varied, so the more detail you can provide the better. Ask the breaker to confirm the part number of the unit they have available and whether it has been tested before agreeing a price.
