Hey there fellow GTI owners. Keep in mind that the MKV has direct fuel injection (same technology used in diesel engines) therefore we have a fuel pump in the engine compartment which makes some noises which you may not have heard in other vehicles which run with unleaded fuel. FYI (The FSI motor runs with fuel preasures well over 1000psi and our injectors a good upto 3000psi) Not bad for a stock fuel system..
