PIWIS 2 vs PIWIS 3
A workshop decision guide comparing PIWIS 2 and PIWIS 3 by Porsche tool generation, job type and PC requirements — with a PIWIS 3 handoff once fit is established.
Choosing between PIWIS 2 and PIWIS 3 comes down to one question: which Porsche generations and jobs do you actually work on? This guide gives a quick decision summary, a side-by-side matrix, the tool identities Porsche uses, and the PC requirements for our PIWIS 3 package — so you buy the right generation the first time.
Quick selection summary
- Choose PIWIS 3 only when your target vehicle appears in this listing's verified coverage (Porsche models up to 06.2022, see the list below) and your job (diagnostics, Guided Fault Finding, coding or programming) matches what the package supports.
- PIWIS 2 is the earlier tester generation. Porsche identifies the two testers as distinct tools — PIWIS Tester III is tool no. 9900, and PIWIS Tester II is tool no. 9818 and 9819 — and PIWIS III software cannot be installed on PIWIS II hardware. They are not interchangeable.
- PIWIS 2's own coverage, capabilities and requirements are not asserted here. This guide does not use a single universal cutover year — match your specific vehicle to the verified coverage list, not to a generation label.
PIWIS 2 vs PIWIS 3: how Porsche distinguishes the two
According to Porsche Cars North America service documentation, PIWIS Tester III and PIWIS Tester II are separate testers with separate tool numbers, and the software is not cross-installable:
| Factor | PIWIS 2 (Tester II) | PIWIS 3 (Tester III) |
|---|---|---|
| Porsche tool number | 9818 and 9819 | 9900 |
| Software cross-install | PIWIS III software cannot be installed on PIWIS Tester II — the generations are not interchangeable. | |
| Vehicle coverage (this listing) | Earlier-generation Porsche work — coverage not asserted here | Porsche models up to 06.2022 (see list) |
| Diagnostics & Guided Fault Finding | Not asserted here | Yes |
| Coding / programming | Not asserted here | Yes |
| PC requirement (this listing) | Not asserted here | Full HD 1920×1080; SATA SSD (not NVMe) ≥480 GB; Intel 8/9 series |
| Best for | Workshops with existing PIWIS II tooling (PIWIS II coverage not asserted here) | Vehicles that appear in the verified up-to-06.2022 coverage list, where the job matches |
Where a PIWIS 2 capability, coverage range or requirement is not backed by an official Porsche document or our verified support records, it is deliberately left as "not asserted here" rather than inferred.
Vehicle-generation boundaries
PIWIS 3 (this listing) supports Porsche models up to 06.2022, including: 911 (992/991/997/996/993/964 families), Boxster (982/981/987/986), Cayman (982/981/987), Cayenne (9YA/92A/9PA), Panamera (971/970), Macan, 918 Spyder, and listed racing/classic models. Models newer than 06.2022 are outside this coverage — verify current coverage before ordering. We do not publish a single "year cutover" at which PIWIS 2 stops and PIWIS 3 begins; instead, confirm your specific model against the coverage list and the tool-generation facts above.
PC requirements (PIWIS 3, this listing)
Full HD (1920×1080) display; SATA SSD (not NVMe), minimum 480 GB; Intel 8 or 9 series processor. PIWIS 2 hardware/PC requirements are not asserted here.
Diagnosis & programming task coverage
For covered Porsche models, PIWIS 3 supports diagnostics, Guided Fault Finding, actual-values monitoring, drive tests, maintenance/repairs, and coding/programming. Online/dealer-account–dependent functions are not asserted here — confirm scope before relying on them.
Legacy workshop scenarios
If your work is almost entirely older Porsche and you already run a PIWIS 2 (Tester II, tool 9818/9819) environment, that tooling remains a separate generation from PIWIS 3 and cannot run PIWIS III software. PIWIS 2's coverage and capabilities are not asserted here. If a specific vehicle you service appears in this listing's verified up-to-06.2022 coverage and the job matches, PIWIS 3 is the appropriate tool for that vehicle — check each vehicle against the coverage list rather than assuming a blanket generation cutover.
