Hello, with my K75 the starter is no longer working. Have already implemented all the tips of the specialists. Nevertheless, “glued” the relay during the starter. You can only stop the process if you disconnect the battery. Therefore, I have already installed a battery disconnector. I have already taken the following measures: – new battery worried because the specialists at BMW have said, that happens when the battery is too weak – without success – starter is replaced – it was the theory, the starter pulls too much power – without success – electronic box replaced – According to the circuit diagram the electronic box is controlled during the starter – without success – the plug at the starter relay has at the plus pole 2 cable – one leads to the starter button, the other to a control device. Have now separated these two cables. If I now push the starter button, which is connected only to the one cable to the starter button, the starter is activated – without success – the starter is activated and there is nothing stuck to the electronics operation. Probably because the starter is not activated via the second cable.
