Has anyone else had this message on the screen? "Anti-theft alarm system Malfunction". It keeps flashing up and disappearing.

This is on a GLB 200, only 2 months old.

Thanks

Probably means what it says. On a 2 month old car that’s a trip back to the dealer for diagnosis.
I just noticed your front collision warning seems to be off. Unless you turned it off or you are parked close to another car or barrier, the front radar detector may be obstrcted or very dirty.

Hi, Have you sorted this issue out? I have been having a same problem with my GLA only 8 months since I have got...

I got exactly same message flashing on and off. A200 amg line 71plate with 14k miles. Just got it in service and it was a faulty control unit - replaced under warranty.

Now after the fault has been fixed it sorted another issue out as well. For a long time every time I opened the car- with the fob or keyless handle, I was getting the message "vehicle unlocked" in Mercedes Me app on my phone straight away which was a bit annoying as we got two A class regostered and my wife was getting it too on her phone no matter what time day and night. It looks like the super early message was due to the same fault. My other A class doesn't send this message that early- rather after a few minutes.
