Wondering if anyone else has a fuel pump that buzzes loudly on idle? Had mine replaced under warranty last week as the dealer agreed it was faulty. 
 

Now the new pump is doing the same thing. 
 

I’m beginning to wonder if this is down to E10 fuel. 
 

Anyone else experiencing this - it’s a 2020 1.5 TSi. 

I'd get it straight back the garage. And if they start being funny, ask to go out in a similar car and see if that's making the noise.

 

The E10 fuel shouldn't be an issue because the car is rated to run it. If you were running E85, then you'd start to assume that was the culprit.
