Just lately, I've been getting a double beep when unlocking. Never had it before and it seemed pretty consistent. No error messages anywhere. Opened and shut the doors/bonnet/boot a few times in case it thought something wasn't open or closed with no change.
Then, just to really muck me about, it's started becoming inconsistent. Sometime it will, sometimes it won't.

Anyone else had similar?

Yes. It was the battery backup sounder. The scuttle drains had become blocked with leaves and the sounder was getting wet. It started intermittently, then got to the point where the alarm was going off randomly.

New bbus fixed it, after clearing the drains under the bonnet pyro-lifters. I used a vacuum with a long thin hose to suck the crap out, I couldn’t reach to pull them out.

Thanks guys.

(I had similar with my previous Mercedes. Dead battery in alarm siren causing all sorts of funnies elsewhere. Just disconnected in the end and went without.)
