500L, 1.4 70KW, petrol, 2013 year



The engine is idling, it works very quietly, when it accelerates, then the noise, on the rise it is heard louder, when it accelerates. The engine was removed, sent for processing, but during the inspection it was established that the engine is OK, ie that everything is within tolerance, the condition is even very good.
After assembling and restoring the engine, it still makes noise.

the pc belt has been removed from the alternator and the air conditioning, noise is heard again.

Does the 500L have this specific problem? Has anyone had and solved a similar problem?

at the first ignition, some thirty seconds, there is no noise, after that, there is a thump again when adding gas. I tried yesterday by idling, immediately in the cold, no noise, and today I started the car and left immediately, there was no noise, the first thirty seconds, until the engine warmed up

Thanks in advance for the answers.
