Hi, could anyone offer some advice to 2 issues.

I have a Polo 2012 and at random times the emergency light/indicators turn on while I am usually driving. All I can do it turn them off at the button.
As my car is still under warranty I have complained to my VW service centre and they seem to not be able to come up with any answers.

Also my 'Bulb Monitoring' symbol on my dash keeps turning on and off at least once a week. As this is usually an indicator that a bulb is out, I have checked and none are out. I had my VW service centre check it and again no answers. When I did have a headlight bulb out this symbol did not turn on.

Has this happened to anyone else.
