Reconditioned Skoda Fabia Gearbox

Fabia petrol or diesel, manual or DSG 7: the engine code alone distinguishes compatible gearboxes

On the Fabia, the production range spans 1999 to 2021 and covers eight distinct engine variants. The engine capacity shown in the documentation is not enough to identify the gearbox: two Fabias carrying the same engine label can be fitted with transmissions that share no common parts whatsoever. It is the engine code stamped on the block — three or four alphanumeric characters — that determines the exact reference. This guide covers 24 codes spread across eight engine variants, with gearbox families comprising 5-speed manual, 6-speed manual and DSG 7.

Petrol units: from BBM to DKRF, gearbox families with nothing in common

The naturally aspirated 1.2 (codes BBM, BMD, BME, CGPA, CGPB) is fitted with a 5-speed manual, as is the 1.2 TSI (CBZA, CBZB, CJZC). These two engine variants share the same gearbox configuration on paper, but the shafts and internal ratios differ: a CGPA code is not interchangeable with a CBZA. The 1.0 TSI (CHZC, DKRC, DKRF) is the only petrol unit that can take either a 5- or 6-speed manual depending on the year and variant; DKRC and DKRF correspond to the most recent versions. The 1.4 TSI (CAVE, CTHE) is the only engine in the Fabia range fitted with a DSG 7, sold without the mechatronic unit but supplied with a new dual-clutch. The 1.6 petrol (code BTS) appears only in the earliest generations and is limited to a 5-speed manual.

Diesel units: three TDI families, two generations of gearboxes

The 1.9 TDI (ASZ, ATD, BLS) is found on the first and second generations. Depending on the code, the associated gearbox is either a 5- or 6-speed manual: ATD and ASZ do not share the same unit as a BLS. The 1.4 TDI (AMF, BMS, BNM, BNV) covers a long production period with a 5-speed manual; the four codes correspond to successive evolutions of the same block, with internal gearbox differences depending on the generation. The 1.6 TDI (CAYA, CAYB, CAYC) appears on the most recent versions, exclusively with a 5-speed manual. For each of these diesel engines, identifying the exact code before placing any order avoids mismatches with the casing or differential.
