Inpa Error: 159
Error 159
In the world of BMW diagnostics, is a classic "ghost in the machine" story. Formally known as NET-0009: TIMEOUT , it usually represents a frustrating breakdown in communication between the EDIABAS software layer and the car's hardware interface. The Story of the Silent Handshake
If error persists, reinstall EDIABAS/INPA and make sure no other software (like ISTA or Rheingold) is blocking the COM port. inpa error 159
- Verify adapter model supports your BMW (K+DCAN for E46+ with D-CAN; K-Line for older).
- On Windows, open Device Manager → Ports and confirm COM port number and driver (FTDI recommended). Reinstall FTDI driver if uncertain.
- If using USB hub, connect adapter directly to PC.
- Verify ignition position.
- Check relevant fuses (on BSI/Body, instrument cluster, OBD power fuse).
- Inspect OBD port pins for damage; verify CAN high/low voltages (~2.5V idle, or ~3.5/1.5V differential when active).
- If possible, probe CAN H / CAN L with multimeter/oscilloscope.
The Hardware Hiccup
: A common cause is a poorly connected or incompatible interface, such as a VXDIAG VCX SE device that isn't properly seated or configured. Error 159 In the world of BMW diagnostics,

- Turn the ignition ON. Not accessory. The dash lights must be on.
- Check Fuse: Find your OBD-II fuse (Look for "Diagnostic" or "Cigarette Lighter" – often fuse 16 or 34 on E46/E39). Replace it.
- Check Battery Voltage: If your car battery is below 11.5v, modules will drop offline. Use a charger.
