Reconditioned SEAT Engine on an exchange basis

On SEAT, a single 2.0 TDI engine capacity covers sixteen distinct engine codes

This is the first pitfall with SEAT engines: relying solely on engine capacity or quoted power output is not enough. The 2.0 TDI is the most striking example — sixteen codes exist across the SEAT range between 2003 and 2020, from BMM and BMN (first generation, fitted notably to the Leon and Altea) through to the more recent generations CUNA, CUPA or DFLA. Two vehicles both badged "2.0 TDI 140 hp" can carry mechanically incompatible engines depending on the year of manufacture and the model. Before placing any order, the engine code stamped on the block — usually found on the vehicle's registration document or directly on the engine itself — is the only reliable reference.

Leon, Altea, Ibiza: engine architectures that don't always cross over

The collection covers six SEAT models from 1999 to 2020, with a strong focus on the Leon and the Altea, followed by the Ibiza, Cordoba, Alhambra and Ateca. On the diesel side, the 1.9 TDI family (codes AVQ, BLS, BRU, BSU, BSW, BXJ) and the 1.6 TDI family (codes CAYC, CLHA, CRKB, DBKA, DCXA, DDYA, DDYB, DGTD) are not interchangeable, even though they share the same basic VAG architecture. The 1.4 TDI (BNM, BNV) is confined to specific versions of the Ibiza and Cordoba. On the petrol side, the 1.4 TSI encompasses seven codes (CAVE, CAVF, CAXA, CAXC, CHPB, CXSA, CZDA) corresponding to different generations and power outputs on the Leon and Altea. The 2.0 TSI, available in eleven variants including AXX, BPY and BWA for the older generation and CCZA, CCZB and CJXA for more recent units, is fitted primarily to performance-oriented Leon models. The 1.8 T 20V (AGU, AJQ, APP, AQA, AUM, AUQ) belongs to the first-generation Leon and Cordoba petrol models and is no longer in current production.

1.2 TSI and 1.2: two families not to be confused on the Ibiza and Leon

The 1.2 TSI (codes CBZA, CBZB, CBZC, CJZA, CJZB, CJZC, CJZD, CYVA, CYVD) is a turbocharged direct-injection engine, entirely distinct from the naturally aspirated 1.2 (BME, CGPA, CGPB) fitted to entry-level versions of the Ibiza and Cordoba in the 2000s. These two families share no common parts whatsoever: an incorrect engine code will result in complete incompatibility. The engines listed here are reconditioned bare engines, available on an exchange basis.
