Common Problems Overseas Workshops Face

If you service cars in Europe, Russia, the Middle East, or Southeast Asia, these barriers stop you from working on Chinese EVs.

No Access to OEM Diagnostic Tools

Brand-specific tools like BYD DiLink or Chery cloud accounts are expensive and unavailable outside China.

No Wiring Diagrams or Repair Manuals

Technical documentation, service manuals, and electrical schematics are rarely available in English or other languages.

Language Barriers for Technical Documents

Chinese-language service materials, fault code descriptions, and parts catalogues require translation and specialist knowledge.

Difficulty Identifying Correct Parts

OE numbers, part numbers, and cross-references for Chinese EVs are hard to verify without the right database or supplier.

We solve all of these — remotely.

Why Workshops Choose NEV Fix

🎯

Specialized in Chinese EVs

We focus exclusively on Chinese new energy vehicles — not a general repair shop adding EVs as a sideline.

🔗

Diagnostics + Parts Supply

Most workshops offer one or the other. We combine both — diagnosis leads directly to the right parts.

Faster Repair Turnaround

No waiting for parts to arrive after diagnosis. We can identify and ship the correct parts in parallel.

💰

Reduce Wrong Parts Cost

Accurate diagnosis means no wasted purchases. Factory engineers confirm OE numbers before you order.
