I might have read this somewhere on the forum. I have every now and again have popping from the front speakers. Its like someone chapping the window and its quite annoying as i think i have ran over something or someone is chapping the window.

Anyone else? Im getting 1806 later this week , so hopefully gone along with the other small probs  

the same here after geting my car from skoda dealer. after almost a months, they solved my problem with numerous of mib3 problems. but now sound poping up from ... speakers when i start the car , but just once . its anoying, also radio came mute when start ing the car. that started in software 1803. before it was normal. 

If I remember correctly there where quite a few reports already about this popping sound. And it was related to the SOS unit. Did you have any errors related to the SOS unit lately?

The popping sound you are hearing is the CAN bus resetting, which means there is a break in the circuit somewhere. In our models, it's often due to SOS fault. When you hear the sound see if your SOS is going from green to red. You may find you get an error on the dashboard. Skoda UK are aware, your car probably needs an update! Check software information in head unit settings.

yes i have had a problem with sos, meaning global with conectivity to any skoda portal, mobile phone etc... but there is no any warning sign in dashboard . i will take a look to green or red light after sound poping up. well something is very wrong with theirs coders.
