Hi Mike
I am afraid I have some not so good news. I received Simon's DiCE promptly and tried his DICE on both my two diesels and unfortunately it didn't work. It could read everything, except for the ECU/ECM module. I tried it with my owned configured VIDA 2012a and Simon's 2014D and had no luck with either.
Simon's DiCE is guaranteed to be a top quality one, with all the chips, so the only other thing that I can think of, is that it may have something to do with the firmware.
As you can see in the images below, both my older DiCE and Simon's brand new one, have the exact same hardware version and everything else is identical, EXCEPT for the firmware. Mine is 5.6.1 and Simon's is 5.6.2.
So I guess I am sending Simon's DiCE back to him.
Only thing I can suggest to you, if you still have any of the other DiCE you have bought, is to try to downgrade the firmware and see if it makes a difference. It is a bit of a gamble and you could possibly brick the dice if not careful, but it may be worth a try.
Hope this helps
Alex
