Modules I can't access include the Airbag, Air Suspension unit, AC, Immobiliser EWS, Rain & Light sensor RLS, Cruise Control GR2 and Central Body Electronics ZKE3. It also only permits access to some modules (I think the same ones) using either cable. I also found online a later (mainly German language) version of INPA (5.06) and installed it under Windows 7 on another laptop.

I still have the same problem, I can only connect to some modules. I did a lot of searching and found some guides which mentioned using a VAGCOM cable with FT232RL chip, so thinking the cable might be causing the problems, I bought one of these and installed a new driver for it. The installation worked for several modules and allows me to read and clear faults etc., but for other modules it won't connect. I bought a USB-OBD EDIABAS cable which came with INPA and other BMW software. I'm using an old laptop running XP and INPA 5.02. The problem is, I can only read and reset errors on some modules on the car, other modules return the error: 'IFH0009 no response from control unit'. The battery was on its last legs so I've replaced that, but still have several issues to track down and want to check/clear some errors using INPA. My car is a 2003 E39 530D Sport Touring, and I'm having quite a few electrical gremlins at the moment.

Hello, this is my first post on this forum I've found lots of answers here previously, but can't find the answer to this one.
