Hi guys, hope you're all well, not been on for a while due to new buisness start up and rr has been behaving , however after stupidly managing to leave my lights on overnight after recharging the battery for 48 hrs on reconnection I find the central locking doesn't work, although the tailgate unlocks with the fob, front wipers and washers don't work although the rear ones do. The alarm doesn't work and niether do the interior lights. I can't seem to find a blown fuse. I assume the bcu controls all these functions but could a flat battery cause it to malfunction ? Or is it protected by a fuse somewhere?
 
Flat batteries cause all sorts of problems. Have you done the lock to lock on the steering? Otherwise disconnect the battery, fully recharge it, reconnect and see what you have after doing the lock to lock reset.
 
Low volts can cause havoc on these things!

It may be time to see if the BCU is setup correctly using diagnostics as the low voltage could have corrupted some settings!
 
Correctamundo Ant, bcu was corrupted , used the manual debug on all comms to reset it. Praise the legend lol
