I’d highly recommend you look at the website for Gendan UK - they are the ‘official’ agent for
MES. They’re very helpful with enquiries too
The reality is you don’t need the full set of coloured cables: most of the time you just plug straight in, but may need the yellow cable now and again.
MES is ‘old’ and happily runs in older, slower laptops (I have it on a cheap 2016 Levono one which I only use for
MES — rest of the time I’m Mac-based. )
The cheap ‘Chinese copy’ ELM connectors that are all over eBay often dont work and need to be adapted by removing (or adding?) a component on the circuit board. So you need the ‘adapted’ version. The units sold by Gendan don’t need that.
I actually use a Bluetooth ‘dongle’ in the car’s OBD socket rather than a wired connection (again bought from Gendan on the advice it would work with an iPhone too — many don't, as I’ve learned having bought a few! The ‘good’ one was about £50 I think?). And if the adapter cables is needed, that goes in the car socket and the Bluetooth unit plugs into the other end of the short adapter.
I have
MES on my iPhone too. Works exactly the same, but it’s an annual subscription rather than the one-off PC payment
The dongle also works perfectly with the very cheap but excellent CarScanner app on my Landy and my wife’s Skoda, and the Panda too. The only thing it can’t do is the very Fiat-specific relearns and oil degradation reset.
