The OBDLink CX is a popular choice, specifically designed with BimmerCode in mind. It’s touted for its reliable connection and ease of use. I found pairing it with my Android phone a breeze, and the connection remained stable even during longer coding sessions. Its Bluetooth 5.1 technology ensures a fast and strong signal, minimizing data loss. The built-in sleep mode and overvoltage protection are nice touches, allowing you to leave it plugged in without worry. While the BimmerCode app isn’t included, the OBDLink app provides useful monitoring and diagnostics on its own.

FOXWELL OBD2 Female to 20pin Extension Convert Adapter OBD1…
This adapter isn’t your typical OBDII adapter; it’s a crucial link for older BMWs. If you own a pre-1996 model with a 20-pin diagnostic port, this is essential for connecting modern OBDII scanners. I used it successfully on my E36, bridging the gap between the old connector and my scanner. Its primary purpose is conversion, not enhanced functionality. It’s a simple, yet vital component for anyone working on older BMWs.
- Converts 20-pin to standard 16-pin OBDII
- Compatibility: E30, E36, E38, E39, E46, E53, X5, Z3 (check your vehicle’s manual)
- For diagnosing pre-1996 BMW vehicles
Pros:
– Essential for older BMW models
– Simple and effective
Cons:
– Limited functionality (conversion only)
– Only for pre-1996 BMWs
Best for: Owners of older BMWs needing to connect OBDII diagnostic tools.
User feedback summary: Positive feedback from owners of older BMWs who needed this adapter to use modern diagnostic equipment. Some users emphasized the importance of checking compatibility.
Autel Original 3-in-1 OBD2 Adapter Cable, 16 Pin to 6/4/3…
This Autel adapter is a multi-connector cable designed for various older vehicles. It’s important to understand this is only a cable, not a diagnostic scanner itself. It allows connection of your scanner to OBD1 6, 4, or 3-pin ports (check your vehicle’s requirements). I found it straightforward to use; the quality felt solid. However, its usefulness completely depends on your car’s support of OBD2 protocols and your scanner’s capabilities.
- Converts 22-pin to 16-pin OBDII (OBD1 connectors as well)
- Wide compatibility (check your vehicle’s manual for compatibility)
- Plug and play
Pros:

Cons:
– Not a diagnostic scanner; requires a compatible device
– Compatibility depends on your vehicle and scanner
Best for: Owners of older vehicles needing to connect a compatible OBDII scanner to various connectors.
User feedback summary: Mixed reviews. Many positive comments on build quality and versatility but emphasize the need to verify compatibility beforehand to avoid disappointment.
Autel Original TCAN003 Splitter Diagnostic Cable for Tesla…
This is specifically for Tesla diagnostics and works only with compatible Autel scanners (it’s not compatible with BimmerUtility). It’s crucial to check your Autel scanner’s compatibility before purchasing. I can’t speak to its performance with Tesla vehicles personally, as this review focuses on BMW-related adapters.
- Compatible for Tesla Model Y, S, X (all years) and Model 3 (after 2021)
- Works with compatible Autel scanners
Pros:
– Supports multiple Tesla models
– Designed for specific Autel scanners

User feedback summary: Positive feedback from Tesla owners using compatible Autel scanners. Users emphasize the importance of verifying both vehicle and scanner compatibility.
Autel Original OBD to Green Type2 9 Pin J1939 and…
This adapter is for heavy-duty commercial vehicles, not BMWs. It bridges the gap between J1939/J1708 ports and the standard OBDII port on your scanner. Your scanner must support J1939 and J1708 protocols to work correctly. This product is included for completeness but isn’t relevant to BimmerUtility.
- Converts 9-pin J1939 and 6-pin J1708 to 16-pin OBDII
- For heavy-duty commercial vehicles
Pros:

Cons:

– Requires a compatible scanner
Best for: Owners of heavy-duty trucks using compatible OBDII scanners.
User feedback summary: Positive feedback from users working with heavy-duty trucks and compatible diagnostic tools. The necessity of protocol support is frequently emphasized.
Practical Buying Advice
Choosing the right OBDII adapter hinges on your BMW model year and your intended use. For most BimmerUtility users with newer BMWs, the OBDLink CX stands out for its reliability and BimmerCode integration. Older BMW owners will need the 20-pin adapter. Always double-check compatibility with your specific vehicle and software.
Final Verdict:
While several adapters exist, the OBDLink CX provides the best balance of reliability, ease of use, and specific compatibility with BimmerUtility for most BMW owners. For older BMWs, the 20-pin adapter is a must-have.
