hi all, im new to this, i woke one morning to find my front windows open and battery flat, when i got the gal going, the central locking as going on and off so i disconnected the battery. once i found the ecu it was soaking wet, i dried it off but my central locking isnt working and my rear doors wont unlock, (seems to have a dead lock on)also problems with interer lights, so i take it i will need a new ecu, is this correct. please help (p reg 2.0l auto)
