Do you know why I can’t just clone my old to new one (that’s what I did) - why it cannot work?
I want to check one more time all grounds and etc before will search for new ecu.
Thanks

No problem, since you did say that the dme was fried. It could be that the cloning didn’t work because there was existing faults or missing data- basically maybe the old dme was to far gone that it couldn’t be cloned to the new dme. There could be a lot of issues with cloning them, that’s just the most relevant one in this situation that’s coming to mind.
But with buying a new dme/cas/key set, you would have to have it in the car and connected, and code it to your specific vehicle order, it’s not too hard with ncs, I haven’t done it it a while but there’s definitely threads about this process.
If you don’t have ista,inpa,ncs , or the rest of the programs, I suggest looking into installing them.
And yes, before doing any of this, double check all the grounds, check all of the fuses in the dme box as well, if not done so yet.
The biggest problems can be caused by the smallest and most stupidest things. But unfortunately, if youre 100% sure that all grounds, connections, and harnesses are in good shape, a faulty dme can definitely cause all these rolling codes of ground issues, b+ issues, line disconnected issues. Because look at it this way, all those sensor connectors all run back to the dme and tell the engines computer how it’s running, or vice versa (dme sending signal for something to do it’s job) and if these things aren’t responding, you can point to a problem in the dme.
