Your Chinese EV,
fixed from China.
Without leaving your driveway.
Remote diagnosis and programming for Chinese-version EVs imported from China. OEM engineers connect to your BYD, NIO, XPeng, Zeekr, Li Auto or other China-spec car over an ENET cable and your Windows PC, then run the same factory tools the dealer uses: OTA updates, fault-code clearing, ECU coding, key programming and crash-lock recovery across 22 brands.

01 Brands we cover
Which Chinese EV brands can be fixed remotely?
The brands the dealer network abroad cannot touch.
All 22 brands below, on Chinese-market, export and parallel-import cars. Imported Chinese EVs often land in countries with no authorised service, or with a dealer who has no access to the OEM software. Our engineers do. If your brand is not below, ask anyway.
Every logo opens the brand page: models, prices, cable and common jobs.

What does a remote session actually fix?
8 jobs we run every week, written up the way we log them.
Each one ends with the car back to normal and a written record of what was done. Every case links to a full answer page with prices, requirements and the questions owners ask us most.
- 01Software
OTA update that never arrives outside China
How do I OTA update a Chinese-version EV imported from China?- Symptom
- Chinese-version car imported from China stays on year-old firmware. The OEM cloud refuses to push OTA packages to a VIN registered abroad, so the bugs the update fixed are still there.
- Fix
- Engineer pulls the correct package for the VIN from the OEM backend and flashes it over the ENET link, module by module, with the factory tool.
- Result
- Latest firmware, new features enabled, release notes shared with the owner.
- 02Fault codes
Permanent warning lamp from a China-only module
How do I clear a permanent warning lamp on an imported Chinese EV?- Symptom
- Telematics box or 4G module in a China-spec car cannot reach its home network abroad. It throws a lost-communication fault on every drive and the dash shows a warning that will not clear.
- Fix
- Engineer codes the module out of the gateway configuration or disables the check in the affected controllers, exactly as a dealer would for a spec change.
- Result
- Warning lamp gone. Other diagnostics remain intact, nothing is masked.
- 03ECU coding
Replacement module needs VIN write and coding
How do I code a replacement ECU or module on a Chinese EV outside China?- Symptom
- Workshop fitted a new BCM, radar or camera but the car rejects it: wrong VIN, wrong variant coding, functions greyed out.
- Fix
- Engineer writes the VIN, applies the variant coding for the exact trim and runs the post-replacement routines from the OEM tool.
- Result
- Module accepted, functions restored, no trip to a dealer that does not exist in your country.
- 04Keys
Lost or extra smart key, NFC card pairing
How can I program a new key for a Chinese EV when there is no dealer in my country?- Symptom
- Only one working key left, or a parallel-import car came with none. Local locksmiths have no OEM security access for the brand.
- Fix
- Engineer authenticates against the OEM security server, adds the new key or card and revokes the lost ones.
- Result
- Keys paired, old ones dead. Works with keys ordered from us or sourced locally.
- 05Accident recovery
Car locked out after a collision
How do I get a Chinese EV driving again after a collision locked the high-voltage system?- Symptom
- After an airbag event the high-voltage contactors stay open and the car refuses to drive, even though the body repair is finished.
- Fix
- Engineer clears the crash record in the airbag controller and the battery management system, then re-enables high voltage after checks.
- Result
- Car drives again. Insurance repair completed locally instead of being written off.
- 06Calibration
ADAS camera calibration after a windscreen change
How do I calibrate the ADAS camera on a Chinese EV after a windscreen replacement?- Symptom
- New windscreen fitted, lane keeping and adaptive cruise disabled with a calibration fault.
- Fix
- Engineer runs the OEM static or dynamic calibration routine while your workshop positions the target board.
- Result
- Driver assistance back online, calibration report saved for your records.
- 07Infotainment
ADB enabled so you can install your own apps
How do I enable ADB and install my own apps on a Chinese-version EV?- Symptom
- The head unit of a Chinese-version car runs Android but only offers a China-only app store: no Google Maps, Waze, Spotify or YouTube, and no local navigation. Developer options and ADB are locked behind an engineering menu the dealer will not open.
- Fix
- Engineer opens the engineering menu with the OEM tool and enables ADB over USB or Wi-Fi, then walks you through the first install of an APK from your laptop.
- Result
- Sideload any APK you like. OEM functions, updates and warranty-relevant settings stay untouched.
- 08New-car acceptance
“New” car delivered with a replaced BMS and rear drive unit
How do I check that a new Chinese EV shipped from China is really new, not a repaired accident car?- Symptom
- Customer took delivery of a car shipped from China and sold as new. Paint, panels and interior were perfect. Before signing the acceptance they asked us to check it.
- Fix
- Engineer checked the security key provisioning of every controller in the OEM system. The battery management system (BMS) and the rear electric drive system (REDS) had never been key-provisioned for this vehicle: neither was the factory unit. Both had been replaced after a rear collision.
- Result
- Written acceptance report in hand, the customer rejected the car and negotiated a genuine new one.
04 How a session works
How does a remote session reach my car?
Six links between your car and the OEM cloud.
You provide the first three. We provide the rest. The engineer's software sees your car as if it were parked in a dealership in Shenzhen.

What you provide
What we provide
Four steps from plugging in to a working repair plan.
- Connect
Plug the car into your Windows PC with an ENET cable and open EV Fix Connector.
- Bridge
A secure gateway connects you to the OEM diagnostic systems the engineer signs into at work.
- Diagnose
An OEM engineer reads codes, runs live tests, and codes ECUs with the factory tools they use day-to-day.
- Repair
The engineer pinpoints the fault and walks you through parts and procedure live during the session.
What do I need to have?
An ENET cable
OBD-II on one end, RJ45 Ethernet on the other. Plugs in under the dashboard. Generic DoIP cables cost about $20 online and cover most brands. Don't have one? We can ship it with the booking.
A Windows PC
Windows 10 or 11 with an Ethernet port and ordinary home internet. You install EV Fix Connector, click connect, and the engineer takes it from there while you watch.
