Hi all i've just bought a 1.2 tfsi 2011 A3.
Have an issue with a loud rattling at 600 - 800 rpm, once i've over 900 rpm the noise is gone. Nothing can be heard from above the engine in the bonnet, it can only be heard in the cabin and underneath towards the engine/car. Car drives perfectly so wondering if it'd a fuel line or something rattling?
I did some research about it potentially being an air con clutch however when i put this on to auto it only makes a slight difference.
Any ideas :)?
