Hoping this Thread will respond to a few questions.
My Vehicle is a (US) BMW E39 528I Sedan. My Vin# WBADM6342XGU0xxxx 1st sold late 1999 or early 2000.
My OBDII (under dash) PORT uses Pins 4,5, 7 & 16. I have a California & US Federal government EPA
sticker attached in the Engine compartment stating the Vehicle is ODB11 (actual spelling vs. ODB2) Compliant.
Pin 15 (L-line) is not populated at either, the 16 pin (under-dash) or 20 Pin Round (under-bonnet) locations.
The last sentence from what I pasted above says “Your 1994-2000 E36 from any country will need an ADS adaptor to access the KOMBI and ABS plus others. This device supports the old school RxD and TxD link fitted to those cars for those modules”.
Perhaps, some clarification. I have purchased (via Ebay) a Blue colored set of cables which leads the purchaser to believe certain capabilities might be achieved with their product(s). This purchase also included INPA version 4. 4. 7 and Ediabas 6.4.3-full version along with a slew of additional programs, that don’t need to be discussed as of yet.
Some issue concerning the hardware may be an issue. What I’ve found might be better understood with a picture or two.
I’ll download the Hardware Pictures and attach two wiring diagrams

Now to get a little bit more specific about the software side of this effort. The first INPA installation never ended with a successful “TWO BLACK DOTS” and offered a couple of error messages when attempting to Link the E39 (F5 function key). The most common error message was a Dialog Box stating “Error compiling script file”. An error was also recorded in the file “inpa.err” file found in the INPA\Bin folder. These error files are not permanent…and have self-deleted or perhaps were replaced with empty containers (place holder with the same file name).
I’m past this problem…at least for the short term. I’ve had some help from a forum member “rebel_ranter” over at Driver.net Forums. I’ve now installed an updated version 5.02 of INPA and it appears to work. However, I’m thinking that the INPA Version 5.02 is too new for my 1999 E39. I make this claim based on what appears to be lack of reference files and the fact that the E39 is not listed on the 1st INPA window when executed. This is currently where I’m stuck at. I’ve since learned just a little about the various INI type files. They can be edited and I’m guessing there maybe some guidelines.
I’m hoping to learn more about this procedure. A possible need to fall back to an earlier version also becomes a question…at least to me. And Now a new question as well...DO I NEED AN ADS ADAPTER?
Looking forward to some feedback and thanks in advance,
