New CL55 AMG owner here. I've been through the manual and can't find anything about this:

When I unlock the car, the blinkers blink once. When I lock it, they blink 3 times. So far so good.

However, every time I lock it, after the expected 3 blinker flashes, the fog lights and rear brake lights start blinking, and never stop until I unlock/relock the car again.

Any idea what that means? I get the impression that the car is trying to tell me something...

This means that your alarm siren component is no longer working. To confirm you can either use a fault code reader or just hold down the panic button on the key fob, you'll notice that the "alarm noise" is not present.

They have a small battery inside and have an expected life of 10 years. Easy to replace DIY, it's in the wheelhouse behind the left front wheel.
