Random increase of indicator volume

[ApocalypseCow]

There a fair few threads on various volume issues but cant see if this has been reported.

Recently I set off in the car and radio was strangely muted. Once I indicated it nearly blew my eardrums out and persisted for the remainder of my 20 min journey whenever I had to indicate. On restarting after an hour all was back to normal.

Same issue again this morning, however did not reset after a few minutes out of the car. Fine again this evening. Anyone know what this is, and if a common problem? As so random and only occured twice, Im not inclined to speak to the dealer at this point.

Happened once for me a couple of months back - not done it again.

Same here-did post details at the time.
Also did not refer to dealer as self rectifying.

ŠKODA Marshall Croydon gave me the solution (thanks Sue).
Park the car safely.
Hold down the system power off button (the one to the left of the volume touch slider) and keep holding it down until the screen goes off, blank, and then powers up again. This rebooted the system and the blasting volume issue was fixed.
Thank goodness.
