Cheap Hyundai i30 Alternator

The i30 ran as the first generation (Mk1) from 2007 to 2012, with the second generation (Mk2) starting in 2012, so a 2010 donor and a 2013 recipient sit either side of that generation boundary and are unlikely to share the same alternator. The safest starting point is your engine code, found on your V5 or via a VIN check, because two cars with the same engine code have a much better chance of sharing ancillary parts than two cars from the same year range with different engines. Give both registration numbers to the breaker and ask them to cross-reference the codes before buying.

Both years fall within the Mk2 i30 generation (2012–2017), so there is a reasonable chance of compatibility, but Hyundai made running production changes to mounting brackets and ancillary components during this generation that are difficult to pin down precisely. The engine code is the most important detail to match, so check yours on your V5 and supply it to the breaker alongside your registration so they can confirm the part fits before it leaves them.

For the alternator, trim level does not affect fitment; Classic, SE, Active, Style, and Premium are badge and equipment differences, not mechanical ones. What the alternator follows is the engine and its associated electrical output rating, so a 1.6 CRDi from a Classic and a 1.6 CRDi from a Premium should take the same unit if the engine codes match. Bear in mind you may receive a unit without any trim-related brackets or covers the higher-spec car had, but the core alternator itself should not differ by trim.

The Mk1 i30 ran from 2007 to 2012 and received a facelift in 2010, so pre-facelift cars are broadly 2007–2010 and facelifted cars 2010–2012. The alternator follows the engine code rather than the facelift date, so if the engine code is unchanged across the facelift the parts often interchange, but Hyundai did make ancillary and mounting revisions during this period. Confirm with the breaker by supplying both registration numbers so they can check the specific codes match before purchasing.

Different engine displacements typically run different alternators because output ratings and mounting points are engineered to the specific engine, so a 1.4 petrol unit is unlikely to be a straight swap onto a 1.6 petrol car. The engine code on your V5 is the definitive detail here — even within the same fuel type and generation, small differences in the code can mean a different alternator spec. Always give the breaker your exact engine code so they can match the part properly rather than going on engine size alone.

Gearbox type does not directly affect which alternator is fitted, as the alternator is driven by the engine and matched to the engine's electrical demands rather than the transmission. However, some automatic variants used different engine management setups that could influence ancillary component specs, so the engine code remains the key thing to match. Confirm with the breaker using both registrations to rule out any ancillary differences specific to your combination.
