please help, I've been hearing this buzzing noise in the background for quite some time, I think it's a very bright electronic buzzing from a unit. No mechanical problem. what could be there.
In the middle under the engine I think...
Thank you for all replies...

Fuel pump?

 

Perhaps, it is possible... Thank you

 

I have a Buzzing noise that sounds like it is coming from the center. I found the source and there are several threads on this sound. It is the A/C pressure line the crosses along the firewall near the wiper.

 

Is your Sound the same as mine in the File?
Thank you
Andi

 

Could be, Mine cycles with the A/C compressor

here is the other thread

Hi,

is the Fuel pump in the front of the car below the engine? I think the alternator could also be the culprit.

The F-Type V6 and V8 have three fuel pumps, a low pressure pump in the fuel tank and two high pressure fuel pumps down low on the right hand side of the engine block, one behind the other.
The front one of those two HP fuel pumps is towards the front of the engine and those pumps have been known to become noisy so that could explain your noise.

Edit - attached is a page from the AJ133 (V8) Technical Training pdf showing the front (primary) high pressure fuel pump. The secondary pump is immediately behind it, just not shown in the diagram.

 

thank you so much for this important feedback...

In the spare parts shop in Germany I can only find one high-pressure pump, not a second one...or are the same pumps installed twice here?

I'm not sure but I seem to remember someone commenting around here somewhere that the two pumps are different with different part numbers.
Try searching for "primary high pressure fuel pump" and "secondary high pressure fuel pump".

 

Thank you, I have the info...
It looks like, than both pumps are the same

DESCRIPTION SRO TIME (HOURS) CONDITION CODE CAUSAL PART

1 pump for each side of the V

 

ah ok, but both pump are on one side installed at the engine, i understood...

 

Yes, both driven by the same driveshaft. I think it's so interesting they are chain drive pumps rather than electric.
