So what is the best OBD II reader to buy and how much do they cost? I'm a bit of a novice with codes and electrical stuff so any info, however basic would be a great help.
Feeling more and more that I should have a go at diagnosing things myself after getting pretty vague responses from various garages; time to get clued up to avoid getting ripped off I think
I use Forscan software and a laptop with a modified USB ELM327 from Tunnelrat...https://tunnelrat-electronics.fwscart.com/ Though I might get the WiFi version too so I can monitor things on my phone when driving, if needed (instead of the laptop in the footwell).
USB version used mainly, but i do have an old cheapy wifi one that cost £3 or £4
which works on the Ford but not on a Renault it seems. Use the torque app
for that, looks like that does not get updated these days.
Vague responses because there are thousands of options. Avoid the cheapy 2 button
jobs which may show only one code even if there are more.
Android? Wifi or Bluetooth works, Apple then Wifi seems the better option. Laptop
or windows tablet with USB ports then a USB powered device should not have
connection issues.
So many ebay ones look identical but they are not. I had one and it would not connect
at the higher speed rquired for these cars.
Tunnelrat also sell 2 versions which they now give you the option FTDI = windows auto
installs the driver, CH340 you need to manually install that one from Chinese sites.
