Arrived as non starter,only fault is communication with ABS module this i haven't investigated as yet. Looking at live data the rpm parameter was not reporting rpm under cranking condition so i scoped the crank sensor at ECU and got a very poor signal,found a poor repair in loom on crank sensor wiring. Now after repairs i have what looks like a good signal at ECU but still no rpm on live data. I get the impression that the garage may have fitted a secondhand ECU and if this was the case and it wasn't matched to immobilizer would this stop the rpm being reported in live data?
