Engine noise

Audi A4 2003
When I bought my Audi fsi, I really thought I was buying the best of Audi, but it certainly leaves a lot to be desired. After three months of buying it, I noticed that there was a cadential noise in the engine, and that such cadence increased when accelerating. I was told it was the fuel pump that was failing and, since then, I've already changed 2 fuel pumps, 1 temperature probe, all the injectors and the common rail, but the noise is still there. It has also been checked if it was an electronic failure, but apparently it is not. So the problem is not yet solved and the warranty is about to expire. What else can I do?

It is an ordinary noise the one you are hearing, even more if it is diesel.
