Hi Peter, I can't get your thread to work so I've replied here.
I recently bought an OBD2 reader off e-bay, about 50 bucks. Reads, resets, live data etc. Mine was badged Konnwei KW808 but here's the same one badged Autel Multiscan 509. Was easy to use and did what I needed. Only issue is apparently doesn't operate of the internal battery if you want to view data away from car.
