Diagnostic tools, hardware, software

Postby EBSF » Tue Oct 01, 2013 6:13 pm

I bought an ELM327 OBD II connector from Amazon and got it working on an old laptop and connected to my wife's Passat (1999 B5 AEB). At the same time, I bought a BMW round diagnostic plug-to-OBD II adapter but haven't been able to get the software to recognize the BMW. The Amazon reviews of the adapter are glowing but not obviously oriented to E30s, so it's easy to imagine a compatibility and standards issue.

So, I was wondering whether I'm stuck getting one of the Peake Research tools, or whether anyone uses or knows of:
- any laptop software that can connect to an E30; or
- a generic OBD II reader that works with a similar adapter.

I'm not wedded to this adapter (it only ran me $5 or $10) but if I can git 'r done with a generic tool that I can use on all our cars, all to the good.

There's special software specific for BMWs. Since E30s aren't even OBD1, the OBD2 adapter shouldn't work at all. I think you need something fully BMW spec.

all your going to get from an e30 is trouble codes since its not even obd1. The stomp testbwill give that to ypu on most e30s without a code reader.

That's what I thought, and thanks. I knew E30s were proprietary and predated OBD I, hence my comment about compatibility and standards, but didn't know if there was a work-around. Basically, I just thought I'd take a crack at clearing my service lights now that I got diagnostics up for the Passat.

I've seen some references and links to Carsoft and may fiddle with that over the weekend. Or, I could just loosen up and bend a paper clip...

Well, yes, if you want to take all the fun out of it.
