Does the GPF on the 1.5 TSI make a noise when it's doing its thing? Like a regenerating DPF does?

 

It's just that I had my car in at Skoda for a replacement fuel pump that was very noisy and now the new one is noisy as well. If the GPF is located from the middle to rear of the car could it maybe be that which is buzzing loudly??

Gpf is in the front section of exhaust where it's hot. . For it to work properly.

 

It won't make any noise, it doesn't have any pumps or anything, it's just a chemical reaction/filtration happening inside it with the exhaust gasses.

 

If the noise is towards the rear and you've just had fuel pump work, I would suspect something Is still wrong.
