Taotao OBD K+CAN cable for BMW E‑Series, FT232RL USB adapter with manual switch, switchable D-CAN/K-CAN

The Taotao OBD K+CAN cable with FT232RL and a manual switch is a dedicated BMW E-series diagnostic and coding cable that reads/clears faults, performs adaptations and applies coding on supported driver modules.

This interface cable is built for BMW owners and technicians who need a compact, switchable adapter to access D-CAN, PT-CAN and K-CAN networks across many BMW E-chassis and some MINI models. It uses the original FT232RL USB chipset for stable communication and includes a driver CD. Note: the cable only programs driver modules — several modules (CAS, SMG, key fob, light control) are not supported.

Which BMW models and years will this cable work with?

The cable supports a wide range of BMW E-series and related MINI models spanning late 1990s to around 2019, depending on the protocol used. It covers older BMW OBD interface cars and later D-CAN/K-CAN vehicles, with a selectable switch to match bus speeds.

• Compatible E-chassis: E46, E53, E60/E61 (from 03/2007 onward), E63/E64 (from 03/2007), E65/E66/E67, E70/E71/E72, E81/E82/E87/E88 (from 03/2007), E90/E91/E92/E93 (from 03/2007).
• MINI models: R50, R52, R53, R55, R56, R57 (new MINI variants listed).
• Older BMW OBD interface support: cars from 1995–1998 (no K-line needed) and 1998–03/2008 models.
• Use switch fully right for E46; most other models use left — verify per vehicle.

What diagnostics and coding tasks can it perform?

The cable handles core driver-module operations: reading and erasing fault codes, performing adaptations and applying coding changes to supported modules. It is designed specifically for driver modules and does not cover all vehicle modules or specialized control units.

• Read and delete diagnostic trouble codes from supported driver modules.
• Execute adaptations and parameter coding where the module allows it.
• Fast and slow CAN bus support enables access to multiple in-car networks.
• Not supported: CAS, key fob programming, SMG transmission replacements, and light-control module programming.

How do I set up and use the cable on my PC?

Install the FT232RL drivers included on the supplied CD and connect the cable to your Windows PC. The cable works best on Windows 7 32-bit; Windows 8/10 may work but is not guaranteed. Disable antivirus software while installing diagnostic programs to avoid false-positive blocks.

• Install driver from the included CD before plugging in the USB cable.
• Preferred OS: Windows 7 32-bit; Windows 8/10 compatibility varies.
• Temporarily disable antivirus during software install and initial run.
• Use the device switch to select D-CAN/PT-CAN or K-CAN modes as needed.

Why is the switch important and how should I position it?

The onboard switch changes the cable’s bus settings so it can communicate with either fast or slow CAN magistrals and older K-line/BMW OBD protocols. Correct switch position ensures reliable communication and avoids bus conflicts; some models require the switch in a particular position to work.

• Switch left: default for most modern models to access K-CAN/D-CAN/PT-CAN.
• Switch right: recommended specifically for many E46 models.
• If a vehicle does not respond, toggle the switch position and retry diagnostics.
• Switching allows diagnosing driver modules without car-dependent reconfiguration.

Who is this for? The Taotao OBD K+CAN FT232RL cable is aimed at DIY enthusiasts, independent BMW mechanics and garages that need an affordable, portable interface for coding and diagnosing driver modules on a broad set of E-series and MINI vehicles. It’s not a full dealer-level programmer — if you require CAS, SMG, key fob or other specialized module programming, choose a dedicated professional tool instead.
