If you get this after modifying the programme, I would revert and see if that fixes the problem.
Then you would have somewhere to look.
And if it still makes the noise you could take it in to a dealer.
Either way sounds like it needs attention.

I brought it to the dealer, he only told me that it is normal to ring the noise when accelerating.
