Vauxhall Corsa corsa nav elite premium 2021 indicator gone very quiet

You can increase / decrease the indicator volume as required , usually via the settings . The procedure varies from car to car and year to year . Unfortunately I dont have the info for your car , Usually very simple . Get on to the garage that messed up the setting and ask them to walk you through the method to increase volume setting .

I spoke to Vauxhall and there is no facility to make it louder. Not ideal.

Going by what you said " My Corsa indicator is suddenly very quiet since Vauxhall played around with the settings. " . they are talking rubbish , they changed it .
It is usually configured through the settings menu , vehicle settings , personalisation , comfort , convenience settings or under different name . All I can find on your car is this om page 106 onwards

It can be done and obviously was on your car when they were messing about with the settings .Don't take no for an answer as they introduced the change . On some earlier models there was a secret menu for settings you could enter for adjusting it but doesn't apply to your year and I dont know if and how to access it on your car . It CAN be done and was on your car by them , possibly accidently or unknowingly by them .

If you go to the end of this video , it shows you how it was done on older Corsas . If you get messed about , contact Vauxhall customer services or try another dealership , explaining what happened and how they have not resolved they fault . I used to love it when we got a car in under these circumstances , fixed it and phoned the other dealership to let them know and rub it in .

Thanks for the tip.
Will call another dealer.
The manual link is for an older model.
My car is a newer shape than that.

I seen that it was a different year but thought there may have been similarities in systems / set up , procedures

Sadly not. I did try the older fixes.
I think my neighbours thought I was nuts flashing them and doing the window washers.....

Lol
