Second Hand Volkswagen Polo Cylinder Head

Both years fall within the Mk5 Polo generation (2009–2017, facelift 2014), but the facelift brought updates that may have affected ancillary and mounting details on the cylinder head, so crossing that 2014 boundary means you should not assume a straight swap. Engine code is the key check — if both cars share the same engine code (for example CHYA or CJZB for the 1.0, or CAYC for the 1.6 TDI), a match is far more likely, but confirm with the breaker against your registration before buying.

Trim level — whether that is S, SE, Match, Beats, or GTI — does not determine which cylinder head a Polo uses; the engine code does. A 1.0 TSI in an SE and a 1.0 TSI in a GTI Line will share the same cylinder head specification, whereas a GTI with a higher-output engine code will need its own matching head. Bear in mind that breakers may strip ancillaries differently across trim levels, so confirm exactly what is included with the head when you get your quotes.

The engine code is the single most important detail for matching a cylinder head — more so than year, fuel type, or anything else on the badge. You can find it on your V5C logbook or by running a VIN check; it is typically a three or four letter code such as CHYA, CJZB, CAYC, or CZCA depending on your variant. Supply that code to the breaker alongside your registration and they can cross-reference their stock accurately.

Yes — petrol and diesel cylinder heads are completely different components and are not interchangeable under any circumstances. Within the same fuel type there can also be differences between turbocharged and naturally aspirated versions, which is another reason the engine code matters more than simply knowing the litre size. Always confirm the exact engine code with a VIN check and provide it to the breaker.

The Mk4 Polo ran from 2001 to 2009 and the Mk5 from 2009 to 2017, and these are distinct generations with different engine families, so a cylinder head from the Mk4 era is very unlikely to be compatible with an Mk5. Even if engine displacement looks the same on paper, the engine codes and internal architecture differ across that generation boundary. Confirm with the breaker against your exact registration and engine code before pursuing this route.

Gearbox type does not directly affect the cylinder head itself, so a head from an otherwise identical automatic Polo and a manual Polo with the same engine code should be the same component. Where gearbox type can indirectly matter is in ancillary items — such as certain sensors or brackets — that may differ, so confirm exactly what is included with the head when speaking to the breaker.
