Reconditioned Skoda Octavia Gearbox

Octavia from 2004 to 2020: when the vehicle's generation determines whether rebuilding your gearbox is the only viable option

Over sixteen years of production, the Octavia spanned three generations and featured eleven distinct engine variants, both diesel and petrol. This longevity creates a very real practical situation: certain gearboxes — particularly those from the earlier generations (1.9 TDI engine codes AGR, ALH, ASV, ATD, AXR or 1.6 codes BGU, BSE, BSF) — are less commonly available on the reconditioned parts market. When no exchange unit matches the vehicle's exact engine code, rebuilding the customer's own gearbox — which is then returned to them — becomes the direct alternative, with no wait for an exchange unit.

5- or 6-speed manual, DSG 6 or DSG 7: the gearbox cannot be deduced from the engine capacity

Several engine variants are paired with more than one type of transmission depending on the year or market. The 1.6 TDI (engine codes CAYC, CLHA, CRKB) can be fitted with a 5-speed manual, a 6-speed manual, or a DSG 7. The 1.9 TDI (engine codes AGR, ALH, ASV, ATD, AXR, BKC, BLS, BXE) alternates between a 5-speed manual and a DSG 6. The 2.0 TDI (engine codes BKD, BMM, CEGA, CFHC, CLCB, CRLB, CUNA) covers the DSG 6, 6-speed manual, and DSG 7. Only the engine code, combined with the gearbox type fitted at the factory, makes it possible to identify the exact reference. DSG 6 and DSG 7 units are supplied without the mechatronic unit.

Petrol: very different TSI families depending on the generation

On the petrol side, the Octavia covers a wide range: from the 1.2 TSI (engine codes CBZA, CBZB, CJZA, CYVB) to the 2.0 TSI RS (engine code CHHB), taking in the 1.4 TSI (CAXA, CAXC), the 1.5 TSI (DADA, DPCA), the 1.8 TSI (CBZB... no, engine code CBZB belongs to the 1.2 TSI— see above) and the 2.0 TSI (CCZA, CCZB, CJXC). These engines do not share the same gearbox: the 1.2 TSI and 1.4 TSI are fitted exclusively with a 6-speed manual, whereas the 2.0 TSI RS and the 2.0 TSI are equipped with a DSG 6. An unreadable or incorrectly noted engine code is the most common source of error when identifying the correct unit.
