FAQ
TL;DR: Over 100 interfaces exist, and "write what you want to do and with what car" still applies. Multidiag "Gold" handles basics; coding DRLs, keys, or mileage across BMW/VW/Honda needs brand-dedicated tools and software. [Elektroda, ZAHYR, post #17567266]
Why it matters: DIYers and small shops want to know how to enable DRLs, code modules, or program keys without buying the wrong interface.
Quick Facts
- Universal Multidiag/Delphi-style tools focus on reading/clearing DTCs; coding/adaptations are limited and generic. [Elektroda, piotrekwoj1, post #17561935]
- Cheap or neutered units may not even connect to BMWs for coding tasks. [Elektroda, ZAHYR, post #17561326]
- Advanced jobs (DRLs, mileage edits, key programming) need dedicated testers/programmers; Abrites uses per-brand licenses. [Elektroda, piotrekwoj1, post #17561935]
- There are over 100 interfaces; define the task and the car before buying. [Elektroda, ZAHYR, post #17567266]
- Examples from the thread: INPA (BMW), VCDS (VW), HDS (Honda), plus Carprog/SMOK/Xprog/VVDIprog for EEPROM/keys. [Elektroda, piotrekwoj1, post #17574693]
Can a Multidiag Pro "Gold" enable DRLs or other coding on a BMW E46/E60?
No. The thread consensus is that BMW coding is not possible on cheap Multidiag units, and connection may fail. Use BMW-specific software instead. [Elektroda, ZAHYR, post #17561326]
Will Multidiag "Gold" correct odometer values or program a new key?
No. Those tasks require dedicated programmers or high-end solutions with paid brand licenses. As one expert put it: "There is no one that does what you want." [Elektroda, piotrekwoj1, post #17561935]
What toolset fits BMW E30/E36/E46/E60, VW Golf 4, and Honda CR‑V from this thread?
Use brand tools for diagnostics/coding and separate programmers for EEPROM/immobilizer. Suggested picks: INPA (BMW), VCDS (VW), HDS (Honda), plus Carprog/SMOK/Xprog/VVDIprog for memory and key work. [Elektroda, piotrekwoj1, post #17574693]
Is a budget Multidiag "Gold" enough for basic diagnostics?
Yes for reading and clearing error codes. Expect limited, generic coding only. It is not a replacement for brand tools for feature activation. [Elektroda, piotrekwoj1, post #17561935]
Why isn’t there one interface that does everything across brands?
Because the market is fragmented—there are over 100 interfaces. Start with the job and the exact car, then match a tool. [Elektroda, ZAHYR, post #17567266]
How do I choose the right interface for my car and task?
- List the exact job (DRL coding, key add, mileage read).
- Map each job to the specific car and module.
- Pick a brand-dedicated tester or programmer that covers that combo. "Write what you want to do and with what car." [Elektroda, ZAHYR, post #17567266]
Will dealer-level testers cover everything I need?
No. Even service testers won’t do all tasks you listed. Some aftermarket devices go beyond service tools, but they cost more. "Even with such a service you will not do everything." [Elektroda, piotrekwoj1, post #17568218]
Is Abrites a one-box solution for coding, keys, and mileage?
Abrites can handle many advanced operations, yet it requires paid per-brand licenses. Even then, it may not cover every task you plan. [Elektroda, piotrekwoj1, post #17561935]
What’s the main risk with cheap "Gold" clones on BMWs?
Some neutered units fail to connect to BMWs for coding. You may read DTCs, but advanced session access can be blocked. [Elektroda, ZAHYR, post #17561326]
Which tool should I use for BMW coding from the thread’s suggestions?
INPA is the named BMW option in the thread. It is a better fit for coding and deeper diagnostics than universal clones. [Elektroda, piotrekwoj1, post #17574693]
What suits VW Golf 4 VR5 diagnostics and coding?
Use VCDS for Volkswagen. It offers deeper access than universal scanners and aligns with VW modules and coding. [Elektroda, piotrekwoj1, post #17574693]
What’s recommended for Honda CR‑V diagnostics?
Honda HDS is the suggested software. It gives proper access to Honda ECUs for diagnostics and supported adaptations. [Elektroda, piotrekwoj1, post #17574693]
Can a universal tool handle DRL activation at all?
Sometimes they can change generic settings, but success varies by car and module. For reliable DRL coding, use the brand’s software. [Elektroda, piotrekwoj1, post #17561935]
I’m not worried about budget—should I still split tools by task/brand?
Yes. There is no single device for coding, mileage, and keys across all your cars. Use different equipment for each activity and brand. [Elektroda, piotrekwoj1, post #17574349]
