In the Audi A1, what is the cause of the sudden loss of power while driving?

I've been experiencing sudden loss of power in my Audi A1 while driving. It happens randomly and lasts for a few seconds, making it difficult to accelerate. What could be causing this issue?

This issue could be caused by a faulty fuel pump. It's a common problem in Audi A1 models and can occur due to wear and tear or low fuel levels. It's best to get it checked and replaced by a certified mechanic.

Another possible reason could be a clogged fuel filter. This can restrict fuel flow and result in loss of power while driving. Regularly changing the fuel filter can prevent this issue.
