Central locking problems

[Pleassy]

I have a SLK (2002)and the locking has gone mad, started unlocking itself, alarm going off, locking on acceleration unlocking under braking.....
Now it drains the battery
Any ideas????

Thanks for your help, unfortunately it was dry , no sign of water & after disconnecting I've still got a drain!
Any. More ideas are really welcome

Earth fault maybe, life to earth, bared wire? I remember a car I had once that when you braked the fuel sensor went to full and changing gear caused the temp gauge to hit maximum, turned out to be a faulty earth strap from the battery to the body.

PS I ripped the PSE apart ( when I had time) found some water ingress and fixed it! You were right my Merc top tech was wrong!
Take a bow ( he's piss off now)
Thanks
