Hi all, great vids. Best help so far, subcribed. I bought a 56 plate Z4 E85 (N52) recently that had been left to stand unattended for 3 years. Guy fitted a new battery and tried to start it. Cranks but no sparks. Flushed the tank and filled with new fuel. Guided by the Vids on you tube I connected INPA and it appears it cant see most of the modules and especially the DME control (ECU) unit. Without the DME relay live the electronics are all dead and hence the no start. Any first step pointers much appreciated. I am guessing that the slow and total battery discahrge taht occured probably created loads of errors. But without being able to establish a link to the DME I am banging my head against a wall. Cheers
