The Deutz Serpic engine range includes various models, each with its own specifications and features. Some of the most common models include: deutz serpic
(SERvice Parts Identification by Computer) is the official electronic spare parts catalog (EPC) software used by DEUTZ AG to identify, manage, and order parts for their wide range of diesel and gas engines. It is a critical tool for service centers, mechanics, and parts distributors working with DEUTZ-powered machinery. Core Functionality | Serpic Code | Description | Likely Fix
If you own a machine built between 2008 and 2018 with a Deutz engine—be it a forklift, a pump, a generator, a crane, or an agricultural tractor—you are likely facing a Serpic interface requirement. | | SPN 2791 / FMI 3 |
| Type | Condition | Procedure | |------|-----------|------------| | (while driving) | Soot < 80% | Engine at operating temp > 70°C → drive above 2000 rpm for 20 min | | Stationary (forced) | Soot 80-120%, no engine faults | Service → DPF Regeneration → Enable Stationary → follow on-screen RPM steps | | Service (workshop) | Ash limit reached | Requires DPF removal & cleaning – SERPIC resets ash counter after |
