Engine bay rattle noise

[Mohammed Khalaila]

I have a 2015 Seat Leon 1.2 TSI ST, It has 108,000KM on it.
So about a few months back a rattling/whining noise started coming from the engine bay, it sounded like it's from the passenger side, at first i thought it was a normal sound it wasn't too loud and also thought it could be because of the cold weather...

the noise got way louder than it was and here we are in the summer so it can't be because of the cold weather, you could hear the noise from the inside of the car when it's idling, if I push the gas pedal the to get the RPM's above 1k the noise goes away.

No faults/codes are showing on the OBD 11.
I tried locating the sound source I wasn't able too, but I think it could be coming from the timing belt area...
I'm pretty sure that it's from the left side of the engine...


Attached a video ...

Does anyone have an idea about the noise ?

Sounds like the high pressure fuel pump, it seems to be common on this range of engines?

Thank you for the reply

is there a way that I can check if it’s the fuel pump making the noise ??

I searched other posts about the HPFP and some suggestions that it could be the cam follower ...

Could some one please point out the location of the HPFP ??

thanks in advance

Hi Mohammed, if you look on You Tube there are lots of videos on this, it affects a lot of VW/Audi group products!

I tried editing the post for some reason I couldn't find the edit button ...

The correct question that I should ask is :

Does it have a round cam follower or flat ??

and could the pump be failing ??

what could it be ??

I do have an OBDeleven, so is there a good way that I can diagnose the pump before taking it apart for visual inspection ??
