[Configuration] Interface = STD:OBD Simulation = 0 EcuPath = C:\EDIABAS\ECU Tracelevel = 3 Then open C:\EDIABAS\BIN\OBD.INI and verify the COM port matches your USB adapter’s assigned port in Device Manager. Example for COM5:
Windows 11 enables "USB Selective Suspend" by default. The interface sleeps mid-job, canceling the API request.
If this scenario sounds familiar, you have encountered the infamous . While it sounds cryptic, it is actually one of the most well-documented—and solvable—communication errors in the BMW diagnostic ecosystem. This article will dissect Error 159 from the transistor level to the software configuration, providing you with a definitive roadmap to a stable connection. Part 1: What Exactly is INPA Error 159? The Technical Definition In the BMW diagnostic stack, INPA (Interpretierbare Programmiersprache für die BMW Diagnose) acts as the front-end user interface. It communicates with the car via the EDIABAS (Eigene Diagnose-Basis Software) middleware. EDIABAS translates high-level commands from INPA into low-level protocols (K-Line, DCAN, or K-CAN). inpa error 159
Remember: Every professional BMW technician has faced Error 159. The difference between a frustrated beginner and a fluent diagnostician is simply working through this checklist.
is an EDIABAS error code that translates to: "JOB_CANCELED" or "JOB_INCORRECT_RESULT." [Configuration] Interface = STD:OBD Simulation = 0 EcuPath
Introduction: The Frustration of a Silent Connection You’ve just hooked up your K+DCAN cable to your E46, E90, or E39. You’ve launched INPA (the Standard BMW Diagnostic Tool). You select your chassis—E90, for instance. You click on the engine (DME). The status bar at the bottom turns green. You hold your breath. And then, instead of live data or fault codes, you are greeted by a pop-up window:
Opened the adapter and soldered a jumper wire between pin 17 and pin 20. Error 159 gone. Case 2: The E90 330i (N52 Engine) After a Battery Change Symptoms: Worked fine before battery swap. After new battery, Error 159 on all DME jobs. Other modules (ABS, Airbag) work. If this scenario sounds familiar, you have encountered
The aftermarket adapter had no bridge between pin 17 (Battery+) and pin 20 (Ignition). The DME stayed in sleep mode.
