Hello everyone,

I recently purchased a 2003 BMW e60 530D sedan. I bought the car in poor condition, and now I'm encountering an issue: the car no longer enters diagnostics mode. When I connect the device to the OBD2 port, it powers up and the lights come on, but I can't establish a connection with the car.

I've tried both generic diagnostics from my mechanic and my cable with INPA (which I previously used for diagnostics, and which works fine on my friend's BMW e90). When I connect the INPA, it is detected when I turn on the ignition and it reads the battery, but any operation I try gives the following message:

IFH-0009: NO RESPONSE FROM CONTROL UNIT

I'm sure the cable and the software are both functioning properly. I'm desperate; the car is in "recovery mode," but the mechanic can't fix it because we can't access the diagnostics.

I know these are limited details, but it's worth a try. Does anyone have any ideas about what might have happened?

Thank you very much!

You most likely need a BMW electrical specialist.
