Fiat

Fiat diesel or petrol: which engine code matches the part you're looking for?

On a Fiat, it's the engine code — not the engine capacity, not the model — that determines which gearbox, bare engine or turbo is compatible. A 2.3 Multijet can carry an F1AE0481D, an F1AE0481N, an F1AE3481D or an F1CE0481D depending on the generation and power output; a 1.9 JTD can correspond to a 188A5000 (100 hp version) or to a 198A3000 or 198A4000 depending on the application. The code stamped on the block is the only unambiguous way to identify it, especially on a Ducato or a Doblo whose variants have followed one another from 1985 to 2024 across several distinct mechanical families.

Ducato, Scudo, Talento: the codes that make up the bulk of the diesel catalogue

The Ducato alone accounts for the majority of available references, centred primarily around the 2.3 Multijet and 2.8 JTD / 3.0 Multijet blocks (codes 8140.43S, 8140.27, 8140.47 for the older JTD units; F1AE and F1CE for the more recent Multijet). The Scudo and the Talento use codes shared with the PSA group and Renault — notably the 4HV / P22DTE for the Scudo 2.0 HDi and the R9M, R9M410, R9M413, R9M452 for the Talento 1.6 dCi, derived from the Trafic III platform. These codes are not interchangeable with one another despite similar engine capacities.

Petrol, TwinAir and automated transmissions: identification points on smaller models

On the 500, the Panda and the Punto, petrol units range from the 1.0 (312A2000, 312A5000) to the 0.9 TwinAir (312A5000 / 263A2000), taking in the 1.2 (169A4000) and the 1.4 (250A1000) along the way. The 500 and the Panda also offer a Dualogic transmission (single-clutch automated manual gearbox), and the 500 Abarth a DDCT gearbox (dual-clutch). These transmissions are sold without their actuator or control unit for the Dualogic, and without the mechatronic unit for the DDCT. On the engine side, the Fiat range covers reconditioned petrol and diesel units as well as turbos — new or reconditioned — notably for the Multijet and TwinAir, two families that place particularly heavy demands on the turbo.
