Independent workshops working on Chinese EVs run into the same wall everywhere: owner’s manuals are free and everywhere, service manuals are paid or gated. In September 2026 we tested the official information channels of 22 Chinese manufacturers one by one, and the pattern held — only a handful publish anything at repair level.
XPeng is the most useful of the exceptions. Its official site publishes free, downloadable maintenance and repair manuals covering models including the G6, G9, L03, P7 and X9. For a workshop that has started seeing XPeng cars, that is currently the best value official source available.
What XPeng Actually Publishes
Our audit of the official user-manual and download endpoints returned 51 official PDFs. If you want the XPeng maintenance manual PDF rather than just the owner’s booklet, this is where it lives: the set includes Maintenance Manuals for the G6, G9, L03, P7 and X9.
| Document type | Publicly available | Value to an independent workshop |
|---|---|---|
| Owner’s manual | Free | Operating warnings and controls — not a repair reference |
| Maintenance / repair manual PDF | Free | Service items, component locations, some removal and specification data — the layer a workshop can actually work from |
| Wiring diagrams / diagnostic software access | Not published | Missing. Complex faults still need OEM or third-party support |
| Flat rate times / DTC library | Not published | Missing. Quoting and fault judgement fall back on your own experience |
The Practical Trap When You Download
XPeng’s download endpoint depends on regional and language context. Request the file without it and the server answers 502 — which looks exactly like a deleted PDF. The combinations that work in our testing carry country, language, language code, client type and timezone fields together. Translated into workshop practice:
- Use the site for the correct market. Do not pull China-market documents to work on a European-market car.
- Use a desktop browser and set the language properly rather than retrying on a phone.
- If a link fails, change region or language before concluding the file is gone.
- Record the revision date of every PDF you download. Model years differ substantially.
Three Things the Free Documents Will Not Give You
- Build and market differences. These are generic documents. The same XPeng G6 repair information may not match the parts and software level of the car in your bay.
- A diagnostic path. A maintenance manual tells you where a part is and what it should be torqued to. It does not tell you whether to test A before B, and it carries no live data, no DTC descriptions and no configuration or commissioning routines.
- Labour time and quoting basis. Without flat rate times, every estimate is a guess, which is uncomfortable when the customer disputes the invoice.
Treat this material as a starting point and not as a diagnostic tool. An XPeng service manual in PDF form has no way to tell you why a fault is intermittent.
How the Other Brands Compare
From the same audit, the barriers across Chinese manufacturers look like this (tested September 2026):
| Brand | Barrier to repair-level information |
|---|---|
| XPeng | Free and public, including maintenance and repair PDFs |
| Tesla | Full service manual free and public, including procedures, torque values and flat rate times |
| BYD | Owner’s manuals and maintenance guides public; repair-level information not released to independent workshops |
| NIO | Owner’s manuals, emergency response guides and rescue cards |
| Li Auto | Owner’s manuals only, across many models |
| Changan | Paid tiers — roughly CNY 60/day, CNY 253/month, CNY 1,500/year |
| SAIC MG / Roewe | Registration plus VIN binding required |
| Geely | RMI registration required; front-end interfaces are session dependent |
| VW Group / Porsche systems | Paid, in the region of EUR 35 per day |
| carti.rioh.cn | National filing disclosure platform. It publishes who must disclose — it does not host the manuals |
That last row matters. Plenty of technicians assume the national platform is where the documents live. It is not — the documents are on the manufacturers’ own sites, and what the platform gives you is a list of who is obliged to publish them.
A Workable Routine for Taking On a Chinese EV
- Establish the exact model, model year and market version first. That decides which PDF is even relevant.
- Start with the free sources: pull and locally archive the XPeng and Tesla documents before anything else.
- Register where registration is the only gate, such as SAIC MG or Geely, even if a VIN has to be bound. Partial access beats no access.
- Before quoting, decide whether a paid day pass is justified. On most jobs one paid day costs less than the labour it protects.
- When a specification is genuinely not published anywhere, log it as an open item. Do not fill the gap with an assumed torque figure.
Common Mistakes
- Treating an owner’s manual as a service manual. Different document, different depth, different purpose.
- Using China-market documents on a European or Middle East market car. The differences land directly on parts and specifications.
- Not recording the PDF revision date. Next time the same model comes in, you cannot tell whether the copy you have is still current.
- Working from forum or cloud-drive “full sets” of manuals. Unverifiable revision, unknown origin, and you carry the consequence of a wrong torque figure.
- Assuming free means easy. Without flat rate times or a diagnostic path, actual job time usually runs over the estimate.
When to Bring Someone In
If all you have is a maintenance manual and the car’s problem is electrical, intermittent, or needs live data to judge, you have hit the ceiling of what documents alone can do. The right move then is to work the data and the diagnostic order with someone who has done that job before — not to keep guessing at parts. That is precisely the gap this site exists to close. If you have an XPeng X9 workshop manual from the free channel in one hand and an intermittent fault in the other, the missing piece is guidance, not another PDF.
Stuck on a Fault Code or a Locked Module?
Our technicians work with Chinese OEM diagnostic tools every day. Send us the VIN and the fault codes — we’ll tell you exactly what to check, in what order, and what it costs.
Need the Parts?
We source OEM and OEM-equivalent parts for Chinese EVs and ship worldwide — brake pads, coolant pumps, charge ports, sensors and more.

Findings are from the EVRepairBase September 2026 audit of manufacturer official information portals, in which each brand’s entry point was tested directly for reachability, interface behaviour and the document types actually downloadable. The free/paid barriers, document types and regional parameter behaviour quoted above come from that test record. No unofficial or redistributed documentation was used or referenced.
