my disco had been sat for about 2 weeks, with a dead battery, i charged the battery, went to lock it, but she kept beeping at me, looked round all the doors, all were shut, i then put the key in the ignition, and got an error on the dash of b with a slash through it, but she started fine, checked the bcm, the next day and it was soaked, so i cleaned it out with solvent, put it back and it was fine again, then another week later, went to use her, but she wouldnt start, checked the bcm again, and again was soaked, cleaned it again, put it back in, but now, im getting a crank, but no start, i connected my hawkeye, was able to communicate with the bcm fine, but when i went to check the engine ecu, i keep getting a communication error..

any help would be great
