The Carly app is nothing like ISTA i'm afraid, it may be convenient, but I wouldn't rely on it at all. ISTA is what BMW use in the workshops, so it makes sense to use the same tool yourself, what you see - they see.
ISTA can also carry out module tests and adjustments and it also has all the fault finding guides and drawings / FUB (functional descriptions) / circuit diagrams etc for the entire vehicle.
The DME tuner detect code was still current in ISTA even after a full reflash to stock and lock, that was the whole issue.
BM3 diagnostics didn't show it, neither did my other OBD fault reader.. So I would have looked a right plonker at BMW if I'd taken the car in with the tuner detect fault showing thinking I must be OK because i've gone back to stock and relocked....
