I bought a non-working 2008 BMW 328xi. The owner said that it needs only a working ECU as per mechanic’s advice. Since the price is only $1k, I had it towed to my residence and had checked checked the starter since it is no crank, no start. The starter is fine and had tested the fuel fuel pump since it does make a sound upon starting. It did work after putting power into it. There are no P codes on the car so I thought that the CAS or the ECU is at fault. I sent the modules with the key and the ECU Pro. The testing was done expeditiously and showed me the video that the testing car started with the modules. So glad that they work and will need only to look for electrical problem. So happy that I sent the modules to them.
