Can anyone advise me on the potential source of a buzzing/rattle coming from the engine bay? Sounds like something is vibrating against something else.
Buzzing could be the fuel pump, depending on which one you have.
Rattling could be the turbo heat shield, the one just behind your head. Or it could be the exhaust brackets, which on the standard one will most likely snap.
Didn't we manage to figure out that it was towards the end of the exhaust pipes? Mainly coming from the left side, It didn't sound like it was that far in.
