[sold][NSW] code reader for early 850s and 850R - $20

jamesinc · Dec 2, 2020

I made this to read codes on my old 1996 850R (Motronic 4.3). The dial has three in-use positions, 1/2/3 o'clock, which can be used to query the ECU, the climate control, and cruise control systems via the OBD-II port. One LED illuminates when you push the button and the other blinks codes back to you.

You can make your own quite easily but this one is in a fancy box and has a nice clicky dial and just plugs straight into your OBD-II port.

Hi James, is this still available? Thanks

Hi George, it's sold sorry. I'll close the ad. They aren't too difficult to make if I recall, you need a multimeter and soldering iron and some JayCar bits. The OBD-II plug I bought from eBay and I believe it was originally an OBD-II extension lead, but I just lopped the end off to get the plug and wiring for my reader.
