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.
